Hi

I've installed QNX 6.5 on Advantech UNO-2272G-J2AE with Intel Celeron Quad Core J1900 (Graphic Engine: Intel HD Graphic). What graphics driver should I use? I've tried devg-intelhd.so and devg-i830.so but they don't work. Only vesabios and svga are working.

Mike Lorenz — Wed, 12 Jul 2017 10:18:04 GMT

Phindows is a remote desktop tool similar to VNC. It is only useabel with photon environment on the target desktop. On the target you have to run necessarily the photon desktop and photon applications.

post117863: Phindows

V K(deleted) — Tue, 11 Jul 2017 20:41:15 GMT

Hello,

I've couple of questions regarding Phindows, things I cannot understand:

1) Is it just a viewer like Remote Desktop on Windows?

2) Can I get source code for Phindows?

3) By user's guide, "Phindows is a connectivity tool that lets you use Microsoft Windows platforms to

connect to and interact with graphical Photon applications running on a remote

Neutrino computer". Does it mean one can "convert" some not QNX-based graphical application and/or primitives to proper Photon-complying format and again display it via Phindows.

Thank you!

Mike Lorenz — Mon, 10 Jul 2017 13:43:04 GMT

Thanks for the information.

That's why in devc-con it's working ? ;)

The program I use has its own redrawing process for blinking text. And there was a timing issue. So it was partially working. Finally, I found a sollution.

In fact, the escape sequences are not working in pterm. But that's not important for me anymore.

post117859: Re: issues with blink attribute for text in photon terminal

Wojtek Lerch — Mon, 10 Jul 2017 13:17:16 GMT

The Photon terminal does not support blinking. It does recognize the corresponding escape sequences that libqnxterm sends to it, and even stores a "blinking" bit in its internal attributes, but there's no code in there to periodically find all the characters marked as "blinking" and redraw them with different colours.

Mike Lorenz — Mon, 10 Jul 2017 11:18:23 GMT

Update:

I figured out, that libqnxterm is not capable using the blink attribute. It seems there's no direct connection of the framebuffer of the library and the pseudo terminal of photon . The program I use has an process which is responsible for active blinking. So there was a timing issue responsible for the lost of the blinking text .

post117836: issues with blink attribute for text in photon terminal

Mike Lorenz — Thu, 29 Jun 2017 14:49:13 GMT

Hi photon experts,

I have an issue with showing blinking text in a terminal application in Photon environment.

The program was ported from QNX4 to QNX6.50SP1 using the library "libqnxterm.a" .

It was programmed for normal console at first . Since QNX4 it is running in a simple photon-app which uses the photon-widget "PtTty" with QNX4 terminal protocol (TERM=qnxm) .

Changing the background color and foreground color works fine. Setting the blink attribute for term_type-function doesn't cause the text to blink .

By using the debugger I can see that in the global structure term_state the attribute for the text was changed in scrbuf .

Testing with pterm:

1. Changing manually the blink attribute for text by using an escape sequence " echo "\033{" " (termcap for qnxm-environment) even doesn't make the text blink in pterm using devc-pty. The background color is changed to grey instead!

2. A second program with almost the same sources as the first program shows blinking text, but only when the size of the pterm window is set to the same char dimension as the program.

3. A third simple test program writing some text with attributes with term_type doesn't show blinking text in pterm windows. The other attributes like underine , highlight and inverse are working.

Testing with console:

1. Blinking text works for devc-con-hid with escape sequence as well as with the test-program using libqnxterm.

Do you have any ideas ?

Thanks in advance

post115737: Re: create dialog and insert to the callback.

Fedor Zharov(deleted) — Mon, 15 Feb 2016 15:17:33 GMT

Hi Afif,

you can use PtAddCallback and PtCreateWidget or ApCreateModule.

E.g. for a button:

PtAddCallback( ABW_Button, Pt_CB_ACTIVATE, button_cb, NULL );

int button_cb( PtWidget_t *widget, void *data,

           PtCallbackInfo_t *info)

post115699: Re: C++ with Photon GUI

Thomas Haupt — Tue, 09 Feb 2016 11:07:13 GMT

Hi Pawel (sorry, missing the correct key on my keyboard...),

I assume your problems originate in PhAB (the Photon Application Builder tool) not originally knowing that you intend to make a C++ application. As you probably have already noticed, PhAB will create a number of source files for you. It also creates "stubs" functions for callbacks you defined for different widgets. It is important (or at least, easiest) if PhAB can know you want to do C++ _before it generates all the code for the first time_.

The easiest way to do so is by telling PhAB to place the stub functions in files with the suffix ".cc". PhAB will automatically recognize this and generate (almost all) the rest accordingly. It will even generate an "abmain.cc" instead of "abmain.c".

When defining callback (or other) functions in PhAB, you can use different special notations. They are documented under:

    http://www.qnx.com/developers/docs/6.5.0SP1.update/index.html#./com.qnx.doc.photon_prog_guide/code.html#FunctionFileNames

So assume you have a button widget and add an "activate" callback, then...

   - naming the callback "btn_act@cb.cc" will add a C callback stub "btn_act()" to "cb.cc" and create the file if necessary

   - naming the callback "btn::act@cb.cc" will add a stub member function "btn::act()" to "cb.cc" and create the file if necessary

   ...

All of these methods will tell PhAB that you're planning to do C++, and let it act appropriately.

There's one potential problem, though -- PhAB will (by default) also try to auto-generate a file named "proto.h" with prototypes of all non-static functions in your project. The prototype generator is not C++-aware, which will likely cause your class methods to appear in "proto.h" and cause compiler errors in various source files. I usually opt to disable prototype generation and manage the prototyping manually. To disable auto-prototyping, open the "Project" menu in PhAB and select "Properties". In the "Project Properties" dialog, go to the "Generate Options" tab and un-check "Scan Source Files for Prototypes".

Attached is a small example project that uses a class "ball_c" to manage an arbitrary number of balls moving across the window and can be added/deleted on the fly. Hope this helps a bit.

Kind regards,

Thomas

post115697: Re: Aplication terminated when 2 script active at the same time.

Thomas Haupt — Tue, 09 Feb 2016 07:35:06 GMT

Afif,

unfortunately, the code and information you posted doesn't tell the whole story. One thing sticking out, though, is that you seem to use two arrays of widget pointers (my_label[] and my_label2[]) and two indices into these arrays (a and b) which keep being incremented on every timer tick. I don't know the exact sizes of the arrays, but letting the indices increase without bounds seems like a bad idea no matter how large the arrays are - sooner or later, you'll always be using "entries" beyond the array boundaries and will experience all kinds of effects.

Also, since PtUnrealizeWidget() doesn't actually delete the widget object, you currently keep piling up unrealized widgets in the background. That's not what makes the application crash, but it causes a memory leak and will deteriorate the GUI's performance over time.

Personally, I'd suggest using two arrays of six entries each. Create (and if possible, also realize) the widgets only once at startup time. Then, at each timer tick, re-calculate every widget's position and use PtSetResource() to set the Pt_ARG_POS resource of the widgets. That way, you can just move the existing widgets around instead of creating new ones every time.

Regards,

Thomas

Afif Grahaditya(deleted) — Tue, 09 Feb 2016 04:02:17 GMT

Hi everyone.

as you can see in the video that I attached in this email, there are 2 buttons to activate 2 scripts. the "OK" button used for activate timer.c, the timer.c is for create widget and move it horizontal and the other is for activate btn_psr.c, btn_psr.c is for create widget and move it vertical

When I press the button one by one ( click the button, restart the application, and click the other button) it's work fine.

But when I click both button in the same time (without restart the application),the vertical widget is work fine, but after the sixth time horizontal widget is created the application is terminate.

do you know the reason why? is there something in my source code that make it happen?

thank you

Hello Afif,

unfortunately your question is a bit too unspecific to be answered right away.

Two questions:

  - Are you having any troubles with the PtSlider widget, or is the zooming your main concern?

  - What is it you are trying to zoom? If it is just an image, I'd suggest using PtImageArea, which

     can be used to display images and automatically supports zooming and panning.

post115582: Photon and ARMv7

mario sangalli — Thu, 21 Jan 2016 14:15:05 GMT

Hy, I' have seen Photon isn't supported on ARMv7 targets:

anyway in the 6.5 OS version uder ARMv7 /usr/photon binary are present:

this means that it can be used, also whitout any official support?

We plan to port some application from ppc to an iMX6, but iMX6 grahic driver in qnx 6.5 is

missing : only screen driver is available for 6.6 release.

The screen driver can works with Photon?

Photon at this time seems to be dead : to port application from ppc architecture to iMX6

will requires a complete rewrite using QT and such is big effort.

There is a way to port Photon on ARMv7 ?

If Photon is dead, there is a hope that its sources will be released to community?

any other suggestion?

Hi Afif,

You can get a string from your widget and convert it to integer type with PtGetResource().

E.g.

PtGetResource(ABW_my_widget, Pt_ARG_TEXT_STRING, &my_string, 0);

my_int = atoi(my_string);

Also, if you need only integers, you can use PtNumericInteger.

Best regards,

Fedor

good afternoon all.. I have a problem

i want to give variable to 3 multi text widget, so if I type "15","20" and "30" on it, then it will become variable for equation:

x=id1+(im1/60)+(is1/3600);

can you tell me how to do it?

post113915: Re: System hanging with devi-hid on i7 smp - QNX 6.5

Philippe Elskens — Wed, 03 Jun 2015 08:31:47 GMT

Hi Oleg

On our application we are using touch screen and mouse. These devices are connected on usb.

At boot time my system starts :

    io-hid -d ps2ser kbd:kbddev:ps2mouse:mousedev -d usb /dev/io-usb/io-usb

    and if later I start  "devi-hid mouse touch" .... the system hang

But now if I slay the driver io-hid and restart it  (in rc.local for instance)  with the following  command:

io-hid  -d usb /dev/io-usb/io-usb

I can start "devi-hid mouse touch" and it works fine.

I'll also try your suggestion

Thanks

Oleg Bolshakov(deleted) — Wed, 03 Jun 2015 08:11:48 GMT

Hi Philippe,

To boot with SMP kernel you have to build boot image in which io-hid and devc-con-hid both launch on the same CPU core. To do this you should use on -C0, for example:

on -C0 /proc/boot/io-hid -dusb /dev/io-usb/io-usb

waitfor /dev/io-hid/io-hid

on -C0 /proc/boot/devc-con-hid -n5 &

reopen /dev/con1

Let me know how it works on your configuration.

Respectfully,

Oleg

Philippe Elskens — Thu, 28 May 2015 08:52:30 GMT

Hello,

Have you experienced problems with iNTEL i7 / Q77 devi-hid driver in SMP configuration.

If we start ph utility, system hangs at "Waiting for input driver" displaying login windows.

If we start photon manually (actually : io-display, io-graphics, pwm, bkgdmgr , etc) all works fine until we try to start "devi-hid mouse". At this time the system hangs.

If we don't start the SMP kernel, we don't have this kind of problem (ph starts without any problem)

Any idea ?

I can open phab on momentics IDE with the same project several months ago. And I do not execute any special step.

post112310: Graphics driver for Intel Atom E6xx (Tunnel Creek)

Andrey Kovalenko(deleted) — Tue, 11 Nov 2014 10:16:54 GMT

Hi all,

I have Lippert CoreExpress ECO2 based on Intel Atom E6xx series processor.

I am using "Intel Crown Bay BSP" with QNX 6.5.1, and in general it works well. But there are no any devg-* driver.

The "pci" utility shows two graphics controllers on board:

                ...

                Class          = Display (VGA)

                Vendor ID      = 8086h, Intel Corporation

                Device ID      = 4108h,  Tunnel Creek Integrated Graphics Controller

                ...

                Class          = Multimedia (Video)

                Vendor ID      = 8086h, Intel Corporation

                Device ID      = 8182h,  Tunnel Creek Integrated Graphics Controller

                ...



I have succesfully started the general driver "vesabios", but I want to use an accelerated driver instead, if at all possible.

So I have several questions:

                1) What device I should use? 4108 or 0x8182? What are the differencies between them, because I didn't find any?

                2) Where can I find an accelerated driver?

Nothing like that is built into phablang, but there is an API that you could use to write your own utility to convert translation files to a format of your choice and back:

Hi folks, I have a small follow up question to the above topic.

Does phablang support the export of the translation files into different file types, for example an export of all strings to a Microsoft Excel file, or maybe an XML file or something similar? I need some easy for humans to read file type for the management.

Are there maybe some shell commands for that? Unfortunately I can't find any documentation of possible shell commands for phablang.

Hi,

the problem was that you didn’t call PtDamageWidget() on the raw widget you created in PhAB; instead, a local static widget pointer ‘raw’ was used  in data_update.c . You’ll need to call the damage function on ‘ABW_raw’ as shown below, then everything works just fine.

Remember: When you create a widget in PhAB and give it a name, e.g., ‘blah’, then that widget will be addressable as ‘ABW_blah’ in your  code.

Kind regards,

Are you sure it isn't called, or could it be you just got something in the drawing code wrong (e.g., bad translation, missing flush...)?

post111246: A question about PtDamageWidget

Xiang Lu(deleted) — Tue, 29 Jul 2014 07:07:26 GMT

  Hi, i'm new to Photon developing and I have a problem with my app.

  I'm trying to use a PtRaw widget to display some graphic made with Photon functions such as PgDrawPolygon, etc. I want to make the raw widget  damaged (redrawn) every 1000ms with a timer.

  In the timer's callback,I call PtDamageWidget(raw) to damage the PtRaw Widget and invoke the drawfunction.But after running it,I found PtDamageWidget() didn't invoke the drawfuntion.Does anyone know the reason,thanks in advance.

post111243: ApSetTranslation() ignores language regionalization

Martin Hollingsworth(deleted) — Mon, 28 Jul 2014 15:49:27 GMT

Hi folks,

I have a Photon GUI running QNX OS 6.4.1. I use the QNX Translation mechanism for different languages.

During application initialization I use this command to initialize the language of my GUI:

int res = ApSetTranslation("de_DE") // for German language in Germany.

This returns 0 for success and loads the language file from the set path of ABLPATH=/usr/photon/translations which results in the file path of:

ABLPATH=/usr/photon/translations/myapplication.de_DE

This mechanism works fine with several languages, as long as I don't seperate between regional versions of one language. As soon as I try to seperate between "de_DE" and "de_CH" I always get the return value "0" for success, but the language file "de_DE" is always loaded.

Example: I have the language files: "myapplication.de_DE" and "myapplication.de_CH". In this case with ApSetTranslation("de_CH") still the "de_DE" language file is loaded.

But if I delete the "de_DE" file from harddrive, the application loads "de_CH" instead. The same behaviour was verified using "fr_FR" and "fr_CA".

I assume there must be something going wrong with the best match algorithm described here in the documentation, unfortunately I can't find out what.

http://www.qnx.com/developers/docs/6.3.2/photon/prog_guide/languages.html#RunningYourApplication

So if anybody has a great idea how to solve this mystery your help is really appreciated!!

Thanks and Greetings,

Martin H.

Problem solved!!!!

Did the following test:

     kept the binary resource files as is (running version)

     copied the original text oriented resource files into the project

     rebuild the project and got a crash



Turned out that some of the original resource files were in UNIX format (CR) and some in Windows format (CRLF). After converting them all to UNIX format the problems disappeared !!

Thanks for the help

Wim Hellenthal — Mon, 21 Jul 2014 15:13:59 GMT

I think I have found the cause of the problems thanks to the suggestion given by Thomas. After doing a diff on the WGT files I noticed a difference with respect to the the end-of-line delimiter handling in some of the .wgtd files. Some of the files used CRLF while others didn't. I'm almost certain that this is the cause. Tomorrow I will do a test and let you know if the problem is solved converting one of the text related resource files to windows format and vice versa.

Again, thanks for the support!

Wim

Hello, Wim.

I tried to reproduce the problem you described. But I couldn't get your results.

If there is a problem to get an example of sources ore test case, can you describe which widgets PhAB you used and make step-by-step instruction to reproduce the issue.

May be using header files from target system in your Momentics project will help.

Regards, Renat.

post111140: RE: ApCreateModule Segmentation fault

Thomas Haupt — Mon, 21 Jul 2014 10:32:12 GMT

Hi Wim,

as you describe the situation, I agree that it probably isn't worthwhile to try creating a test case.

Could it be that the code was originally built using a significantly older PhAB/Photon/ap version? In that case, it should be sufficient to once slightly modify all PhAB modules, save, and generate.

If we wanted to find out what exactly is happening, you might also (after updating the application as lined out above) perform a "diff" between the new and old versions of the wgt/*- and the src/ab* files. That might give us some indication if e.g. a changed resource format is causing your troubles.

Regards,

Thomas

Dear all,

First of all, thanks for the support.

I think it is not so easy to come up with a reduced test case. The code is proprietary and developed by a third party. It involves quite a lot of code. I could try to create another project for testing but most likely that code will work as expected.

I now wonder if it could have something to do with the fact that the complete source was originally designed and build on a different system. After modifying the resources I can build again and again without any problem running the executable (at least not the problems I've found so-far) . Note that I came across a related issue where no segmentation fault occurred but where one of the dialog s did not show up.

post111138: RE: ApCreateModule Segmentation fault

Thomas Haupt — Mon, 21 Jul 2014 08:04:32 GMT

Hi Wim,

this sounds odd enough. First, saving alone will not generate the files that "Generate UI" will. The former will mostly affect the *.wgt? files in your project's wgt/ directory, whereas the latter creates (or updates) a series of source files in the src/ directory. Most of those will have names beginning with "ab":

  Usemsg

  abLfiles

  abWfiles

  abdefine.h

  abevents.h

  abimport.h

  ablibs.h

  ablinks.h

  abmain.c

  abplatform

  abvars.h

  abwidgets.h

  indLfiles

  proto.h

Additionally, this process may create or update source files which were explicitly specified in your widget's callbacks etc.

You can delete all of the "src/ab*" files to force a re-generation of those upon "Generate UI", but PhAB will never re-generate or update existing code. E.g., a callback routine already existing in one of your source files will never be touched by PhAB. Consequently, you might add a pre-build action to your IDE project that could remove all those fully generated "ab*" files. But again, that will not cover everything.

In theory, the source of your problems could be either the _code_ generated by PhAB, or it could be the widget definitions (in wgt/*) that are bound into your application by 'phabbind'. Hard to tell which one is the actual culprit.

Can you come up with a reduced test case for this issue? If so, it would be good to have the source - and perhaps the binary and a core file as well.

Regards,

Thomas

Subject: ApCreateModule Segmentation fault

Dear all,

I'm having a serious problem with binding the application builder (PhAB) resources. This is what I do

Within the PhAB (as part of the IDE):

        - Generate UI

        - Save

or the other way around. I assume that both action will generate new resource files (including header files) when something has changed. Notice that in the error situation nothing actually has changed.

From the IDE

Compile all the source files (the post build binds all the resources into the executable using phabbind).

Now the following happens for some (not all) of the dialogs that are part of the GUI. Whenever I try to create them I get a segmentation fault. This looks as if there is a mismatch between the generated header files and the position of the resources in the executable. I can only avoid this type of behaviour when modifying the respective dialog by e.g. move the button one pixel and then saving the project again from within PhAB. After recompiling the whole project the dialog will pop-up as expected. But the error will still occur on other dialogs within the project. I can only avoid all the errors by editing all the dialogs and stuff from within phAB. This is however tedious and error prone. I also does not give me any confidence that this will always work.

The question is how this can happen and what to do about it. Is there a way to regenerate all the phAB generated files every time I build the project from within the IDE? More important I don't understand why there is a mismatch in the first place. Is this because the generated phAB files are corrupt or has it something to do with the phabbind program?

Hope someone can help!

By the way I'm using:

     Momentics IDE version 4.7.0

     PhAB version version 2.03

     Target (x86), version 6.5.0

I'm using a windows 7  machine as host

Oleg Bolshakov(deleted) — Sat, 19 Jul 2014 09:29:01 GMT

Hi Robort,

PhCreateImage() call sets clearing flags in p_phimage structure. This clearing proceed after PtSetResource. You can set flags to off state just after PhCreateImage(), e.g.:

     p_phimage->flags &= !Ph_RELEASE_IMAGE_ALL;

As a result the memory won’t be cleared. Don’t forget to clear memory when loaded image will not be needed.

Respectfully,

Oleg

Wojtek Lerch — Thu, 10 Jul 2014 13:36:31 GMT

You mentioned that this process is single-threaded. What is this 3rd party app relation to Photon? How is it called from Photon's event loop? Is it via some sort of callbacks (including workprocs or input procs)? The stack trace shows that ReadServer() is called from something in libc -- is that correct? I assume you're calling PtHold() because this process has widgets; have some widgets already been created at the point where it crashes? Or is there a chance that the 3rd party lib somehow manages to call your PtHold() before you have managed to initialize your Photon UI?

Aram Kim(deleted) — Thu, 10 Jul 2014 04:31:16 GMT

Thanks you again.

I'd search more about PtInit(), PtEnter(), PtLeave(). Thanks you.

Stack trace is like this:

(gdb) bt

#0 0xb8330c25 in PtHold()

from /usr/qnx650/target/qnx6/x86/usr/lib/libph.so.3

#1 0x08053fa3 in receiveGMC()

#2 0xb83fd857 in ReadData() from gmc_client_qnx.so

#3 0xb83fde15 in ReadServer() from gmc_client_qnx.so

#4 0xb0320070 in ?? () from /usr/qnx650/target/qnx6/x86/lib/libc.so.3

(gdb)

receiveGMC(), ReadData(), ReadServer() are 3rd party library functions.

Unfortunately we don't have their debug possible library of GMS client, it is difficult to watch inside of them.

Wojtek Lerch — Thu, 10 Jul 2014 04:18:56 GMT

No, I didn't mean to suggest that the crashes are caused by the fact that your PtHold() calls aren't paired with PtRelease() calls -- apologies if it sounded that way. The only reason I asked about that was because I was curious what those unpaired calls were meant to achieve, and whether there might be a more "proper" way to achieve it. That curiosity was not directly related to the crashes.

PtHold() is a simple function. The only two situations that can cause it to crash (other than general memory corruption) are when you call it without initializing the widget library first (via PtInit() or the PhAB equivalent) or when you call it without holding the library lock (i.e. after calling PtLeave() or without calling PtEnter() where appropriate). That's why I asked about threads and stack traces.

Aram Kim(deleted) — Thu, 10 Jul 2014 00:56:26 GMT

Thank your for your answer.

Unfortunately send/receiver messages are done by 3rd party library and it doesn't use multi-thread.

The library works as like ping service. Just receives message and sends it again.

And actually I used other functions which contains PtHold().

Real source is like this:

PtClearWidget(displayPane_tp);

ApCreateModule(pLink, displayPane_tp, NULL);

PtReRealizeWidget(displayPane_tp);

And according to the stack trace my software died when calling PtHold() or PtRelease().

So I think pairs of PtHold() and PtRelease() call is not a problem.

Thanks again to your help.

Wojtek Lerch — Thu, 10 Jul 2014 00:39:56 GMT

How do you receive the message?  Is your code multithreaded?  Could I see a stack trace from a core file?

What are you trying to achieve by calling PtHold() without (as it seems) calling PtRelease()?  The purpose of PtHold() it to prevent widgets from redrawing themselves multiple times when you're making multiple changes to them, and the intended use is that you call PtHold(), then make your changes to widgets, and then making a matching call to PtRelease().  Yes, PtHold() "just" increments a counter, but it has to find the counter first (and that's probably where it crashes for you) and there are quite a few pieces of code that the counter affects.  The expectation is that you should have a matching PtRelease() (in the same thread) for every PtHold() before you return to the event-processing loop, and that you will either not do anything blocking in between, use one of Photon's "modal" mechanisms to do the blocking, or call PtFlush() before blocking, to ensure that the widgets redraw themselves according to their current state before you block.

post111007: Problem when using PtHold()

Aram Kim(deleted) — Thu, 10 Jul 2014 00:11:20 GMT

I'm developing a graphical user interface software using PhAB.

I made some simple program.

It's function is like this:  button click -> just call PtHold()

on_button_click()

{

   PtHold();

}

It works well.

But I changed it like this: button click -> send event to server -> receive response from server -> call PtHold()

regist_receive(&receive_from_server);

on_button_click()

{

   send_to_server();

}

receive_from_server()

{

   PtHold();

}

In this case program causes memory fault every time. (SIGSEGV)

It is same for PtRelease() too.

As I know PtHold() just increases count. I guest it's implementation would be simple.

So I can not image why it causes memory fault. It is so weird.

Anybody can explain about this phenomenon?

You can launch phablang from within PhAB (appbuilder). Look under Project -> Language Editor. Or you can first start "appbuilder", and then use a command prompt (or Cygwin shell) to type: ph -run phablang.exe

Either way you need a proper PhAB-for-Windows installation at the customer site. PhAB must be running because it starts the required Photon components. There are a lot more files needed than the ones you list.

Just copying phablang.exe, phablang.res, ph.dll, cygwin1.dll and languages.def and then starting it, results in an ACCESS_VIOLATION and a stack dump.

Hello,

I have a 4D Systems LCD Panel (4dcape-43) connected to a beaglebone black running qnx.

I'm using the devg-omaplxx driver contained in the BSP (bsp-nto650-ti-beaglebone-sp1-trunk-201209071340).

A logic analyser connected to the lcd interface shows that every valid frame is followed by an empty one. Therefore the display is flickering.

I suppose Photon is only filling one buffer. The Datasheet for my TI am335 processor shows that the lcd controller reads from two alternating buffers using DMA.

Please reply if you have any idea concerning this error.

Hi,

I would draw some things in direct mode in QNX 6.4.

I use PdCreateDirectContex -> PdSetTargetDevice -> PdDirectStart -> PgFlush -> PdDirectStop -> PhDCSetCurrent( oldOneDC ). It looks ok, draws really fast on screeen but in QNX help files someone wrote that I should take care about PhEvent.type = Ph_OFFSCREEN_INVALID -> subtype Pg_EXITED_DIRECT.

For this subtype in callback function I'am recreating direct context ( previously releasing old one ). Right after I reinitialize context program goes to function thats redraws my PtRaw widget that contains things I draws previously. So it redraws it again and again and again....

Is somewhere a nice simply examle for using these functions and taking care about moving window/redrawing on timer/ redrawing on event?

post105975: single-instance minimal system font rendering

Jeffrey Percival(deleted) — Wed, 16 Oct 2013 16:15:43 GMT

I have an app running in a minimal embedded system (no GUI, window manager, none of that) and need to render small strings (e.g "hello world") into bitmaps. I don't want to do any message passing or font servers, and will be happy with a single simple font for all strings. I'd like everything to be resolved at compile time. I can't quite tease out how to do this from the documentation. This description seems to match my desires:

Finally, you might determine that you need some applications to run private font server instances to improve font rendering speed.

Can anyone point me to the required compile-time requirements for this?

post104572: Problems with devg-lx800 and Photon on qnx 6.3.0

Erol Oezguerbuez(deleted) — Tue, 27 Aug 2013 14:52:31 GMT

Hi,

because of the bug "a lockup produced by running pidin repeatedly in a pterm window" with the devg-lx800 on our

Geode machine running QNX 6.3.0 SP2, i've updated this driver with the one from Patch ID 732 which should solve exactly

this problem.

With the new driver photon will not start again and the screen is freezed.

Following settings are used:

io-graphics -dlx800 vid=0x1022,did=0x2081,index=0,photon,xres=640,yres=480,bitpp=32 -pphoton

Any suggestions ?

Jaroslav Rab — Tue, 18 Jun 2013 10:12:58 GMT

post102071: Re: PtDivider childs does not resize at runtime using PtSetResource()

Jaroslav Rab — Thu, 06 Jun 2013 20:16:31 GMT

I'm really sorry for the long delay.

In the meantime I've found out what causes the problem - PtDivider absolutely ignores the Pt_ARG_MIN_WIDTH flag in its childs. This by the way means that setting this value (either before childs first realization or anytime after) does not trigger a widget resize as it would if it wasn't inside of PtDivider. I need PtDivider obey this flag or another solution to "stop" the user-mouse-dragging at some point defined by me.

There is another caveat with setting the overall PtDivider width - see cb_resize00() in the source code for a hacky, but working solution.

post101782: PtDivider childs does not resize at runtime using PtSetResource()

Jaroslav Rab — Tue, 28 May 2013 19:42:36 GMT

Why does not PtDivider allow to change the size/dimensions of its childs at runtime using PtSetResource()?

I wasn't able to manage resize PtText/PtButton childs in the PtDivider container using PtSetResource(). Neither of Pt_ARG_MIN_WIDTH, Pt_ARG_MAX_WIDTH, Pt_ARG_WIDTH, Pt_ARG_DIM has any effect. According to documentation there is the Pt_CALLBACKS_ACTIVE flag in Pt_ARG_FLAGS to allow calling the drag callback (if set) when any child changes its size. This flag led me to idea that it's possible to change the childs size at runtime. But it seems I was wrong. Or is it really possible?

Glad to hear you got it working and thanks for solving it, I'll try this out and see if it works for me too. I can't remember now why I stuck with the cygwin 1.5 series (maybe trying to be as compatible as possible?).

I ended up going a different route rather than persisting with PhAB under Windows, which was to map a shared drive under the VirtualBox QNX and use ab on it, with the IDE running under Windows. Im sure there are potential pitfalls doing it that way but it works for my needs.

post101457: Re: Custom container widget crashing Windows hosted PhAB

Matthew Jin — Wed, 15 May 2013 16:07:25 GMT

okay I got it working yesterday, basically you need to update your cygwin to the latest version so that it actually works in win7 64bit properly.

Here is the basic steps:

1) I upgraded my cygwin from 1.5.5 to 1.7.18 (latest version as of today) there is no way to go back to older version after you upgrade so I would make necessary backup just in case you need to go back.

2) update your compiler_gnu.h and types.h in your c:\QNX650\host\win32\x86\usr\include\libqnx\sys with the attached file

3) replace the cygwin1.dll in your c:\QNX650\host\win32\x86\usr\photon\bin

4) replace the string.h file in your c:\cygwin\usr\include\ (this is kind of cheating but I had no time to troubleshoot and update all QNX .h file to match the new cygwin gcc version. I know I don't use string.h in my dll so just took the string.h from the old cygwin 1.5.5 version.

5) now you can compile and link your custome widget code with following commands

(compile)

gcc -c -nostdinc -I /lib/gcc/i686-pc-cygwin/3.4.4/include -I/cygdrive/c/QNX632/host/win32/x86/usr/include -I/usr/include -I/cygdrive/c/qnx650/target/qnx6/usr/include custom.c

(link)

Matthew Jin — Tue, 14 May 2013 18:16:00 GMT

I have the exact same problem. I am currently working with QNX support but I don't know if it will be resolved since PhAB is basically going away. But they should still supported it up to 6.5.0 I think. Were you able to even compile with your cygwin 1.5.25? I tried this and I get bunch of compile errors. I know I had to update two .h file (type.h and compiler_gnu.h) supplied by QNX originally to compile under windows XP but this same approach does not work under windows 7 and I think it has to do with cygwin1.dll compatability. I would be curious to know how you compiled in XP and how you are doing it on Win7?

post100519: File names not visible in Photon File Manager

Nikhil Prad — Fri, 12 Apr 2013 13:49:49 GMT

I am new to the QNX 4 system.

In the Photon File Manager(PFM), the actual list of files (and folders) is not visible. The files are still there, I can select them, open them, edit them, etc, I just can't see their files names. I am assuming that this is an issue with the text colour. Unfortunately I cannot find any options for altering the text colour in the PFM Configuration options. The attached image shows what my PFM window looks like. In the image, I have a file selected, but the name of the file is not visible.

Any help would be appreciated.

I planned to add text selection/copying and horizontal scrolling using mupdf 1.2 engine, which must come out soon. It is a matter of one/two weekends to do this :)

If you like to do this yourself, take a look into the phmupdf_draw_content() function, there one variable called offset, it is y-offset of the page, you have to implement x-offset using the same algorithms. And also you have to unlock zoom levels, currently maximum zoom level is calculated using fitting page to the window dimensions.

Yes, I  have pasted the output from the console to my posting. egl-gers returns immedeately, there is no way for me the start pidin while it is running:

# time egl-gears

gf_dev_attach(): No error

    0.03s real     0.01s user     0.00s system

But I get

No, PtOSContainer is used just for non-flickering graphics update. I think problem could be in blitting from offscreen memory to PtOSContainer, since I have not implemented horizontal scrolling, it can be an issue.

Did it actually print:

Run it in the background, egl-gers &, then type:

slay egl-gears

get the output of 'sloginfo':

OK, I missed the point about starting from the command line. If starting from the command line does not work, then there is most likely another problem.

Let us forget Photon for now, and concentrate on GF.

Start io-display.

Then try to just run egl-gears, do you see anything, or get an error?

Hi,

my first attempt to get the GUI running was to enter commands which I mentionend in my original post from the command line of the console. Since it did not work, I tried to put them into the startup script (*.bsh file of the system builder project), but the result was the same.

When I boot without the GUI commands in the startup script, there is no process called io-display shown by pidin. There are no other startup scripts.

Is there a way to check the file system is consistent besides waiting for some seconds before starting the drivers manually and checking that there are no error messages displayed by sloginfo?

BTW, I start several other drivers like network, I2C, audio and USB earlier in the *.bsh script; they work without any issues.

The content of display.conf is

# cat /etc/system/config/display.conf

did=0

modeopts=/etc/system/config/imx35.conf

display {

Are you sure the file system is consistent at the time your are first trying to start io-graphics, or some script is not trying to mistakenly start io-graphics twice?

What do the contents of your display.conf look like?  How are you starting io-display?

Kapil Gadgil(deleted) — Mon, 25 Feb 2013 09:13:42 GMT

Hi Mike,

I tried enabling offscreen memory context and I do see an improvement in memory usage.

However the horizontal scroll functionality which I implemented using PtScrollContainer stopped working.

Only the PtPane gets scrolled instead of the whole drawing area.Following is the code I used to create scroll container.

app->phwindow=PtCreateWidget(PtWindow, Pt_NO_PARENT, winargc, winargs);

/* Create PtOSContainer widget for flicker-free updating */

   PtSetArg(&winargs[winargc++], Pt_ARG_DIM, &app->window.dimension, 0);

    app->phoscontainer=PtCreateWidget(PtOSContainer, app->phwindow, winargc, winargs);



  /*Create ScrollContainer for Horizontal Scroll in This Application*/

    winargc=0;

    PtSetArg(&winargs[winargc++], Pt_ARG_DIM, &app->window.dimension, 0);

    PtSetArg(&winargs[winargc++], Pt_ARG_SCROLLBAR_Y_DISPLAY, Pt_NEVER, 0);//Vertical Scroll bar is not displayed as it is already implemented.



app->scrollarea=PtCreateWidget(PtScrollContainer,  app->phoscontainer, winargc, winargs);





    /* Create PtRaw widget for drawings */

      winargc=0;

PtSetArg(&winargs[winargc++], Pt_ARG_DIM, &app->window.dimension, 0);

    PtSetArg(&winargs[winargc++], Pt_ARG_FILL_COLOR, PgRGB(0x70, 0x70, 0x70), 0);

    PtSetArg(&winargs[winargc++], Pt_ARG_RAW_DRAW_F, phmupdf_draw_content, 0);

    PtSetArg(&winargs[winargc++], Pt_ARG_POINTER, (void*)app, 0);

    raw_cb.event_mask=Ph_EV_BUT_PRESS | Ph_EV_PTR_MOTION_BUTTON |

        Ph_EV_PTR_MOTION_NOBUTTON | Ph_EV_BOUNDARY;

    raw_cb.event_f=phmupdf_content_callback_raw;

    raw_cb.data=(void*)app;

    PtSetArg(&winargs[winargc++], Pt_CB_RAW, &raw_cb, 0);

    /* Create the PtRaw widget */

    app->phcontent=PtCreateWidget(PtRaw, app->scrollarea, winargc, winargs);

Does it have any relation of scroll container created on PtOSContainer and offscreen-memory context enabled at the same time?

The font server loads the old fashioned fonts but doesn't let display the characters in pterm.

And, I'm only able to choose the old font in pterm properties if the flag "f" is changed to "Nf" in the "fontdir" file.

That's why I wanted to convert the old files using the new header data.

Maybe there's another way: creating a bdf file from the raw character data and converting this bdf using "bdftophf2" . The specs are available at Adobe and x.org ...

Yes, there are two types of phf fonts, PHF and PHFv2. There are both supported by the font server.

Is there a problem, or do you want the header definitions for PHFv2?

I did some reverse engineering.

Theres are differences between old photon fonts and new photon fonts in the header.

The data the bitmaped fonts seems to stay the same.

Exchanging the pure data of e.g. a 8x16 point sized font (pcs16.phf) doesn't work while preserving the offset to the data (0x3f) and the file size. "mkfontdir" doesn't accept it. I guess, there's some checksum or CRC in the header.

The header of the old font is fixed sized.

The header of the new fonts is dynamical sized because of the font name. So there are small different sizes between similar font files e.g. between pcs16.phf and pcss16.phf .

post99374: photon font issues porting from QNX 4 to QNX 6

Mike Lorenz — Wed, 20 Feb 2013 13:44:15 GMT

Hello!

I have some issues porting from QNX4 to QNX6.5x

I use selfmade .phf - fonts from QNX4 containing own symbols in it for a

small photon-application window running a terminal in it.

Changing the font using an escape sequence ( echo "\0033\"fphffontname\""

) causes the terminal to change the size of a terminal because of the

character size, but the text is invisible. changing back , eg. to pcterm14

works well (text is visible again).

The same happens to pterm windows.

I have done:

I put the *.phf in the /usr/photon/font_repository and using "mkfontdir -b

-d /usr/photon/font_repository" for creating new entries in fontdir file.

This works.

Watching all installed/registered fonts with a test program using

PfQueryFontsCx(...) shows up my fonts. But, looking to the properties of a

pterm window doesn't show the own fonts in the custom list.

One Difference, I figured out is that the preinstalled fonts

FontDetails.flags uses one more bitstring

our fonts flag is 0x11 (PHFONT_INFO_FIXED|PHFONT_INFO_PLAIN) ;

instead eg. pcterm14 is 0x111

(PHFONT_INFO_SANSERIF|PHFONT_INFO_FIXED|PHFONT_INFO_PLAIN)

Using "fontinfo -f fontfile.phf" also shows up one more attribute for the

preinstalled fonts: ( "[__PHF_P2_ATTR_][__PF_FIX_]" contrary to our fonts

: "[__PF_FIX_]" )

Rendering the fonts using "fontinfo -r ..." shows up all characters.

I guess there are some information missing in the header of the font

files.

Is there any documentation about the header or structure of phf - font

files ? I didn't found any in the forum or www .

Or is there a font editor ?

btw: the font from Mike Gorchak (

http://community.qnx.com/sf/discussion/do/listPosts/projects.graphics/discussion.photon_microgui.topc23114

) works well too.

Thanks in advance

fz_malloc_*() is used everywhere in the fitz library. Each page rendering operation calls numerous fz_malloc_*() functions.

Hi Mike,

After debugging phmupdf on our QNX system , we found that the call PhCreateImage() in phpdf_load_page() was failing and returning NULL.due to which phmupdf crashed.

This was happening during continous zoom operations.

As a solution to this , can I put a check in phpdf_load_page() to check for PhCreateImage() to return NULL and in this case I may revert back to the previous zoom level.What all structures I may have to clear and handle.Attaching the conditional statement :

if(NULL != app->page_image[slotno].page_image_phi)

            {

             printf("pointer not null\n");



         temp_ptr=app->page_image[slotno].page_image_phi->image;

                 w=app->page_image[slotno].page_image_phi->size.w;

                 h=app->page_image[slotno].page_image_phi->size.h;

                 pitch=app->page_image[slotno].page_image_phi->bpl;

            }

            else

            {

             printf("NULL Image!!!!! Cannot allocate memory\n");

                  //Return to previous zoom level

            }

Also in some cases of scrolling and zoom I observed the fitz library function fz_malloc_array() throwing an exception for not enough memory(). Can you pinpoint me the exact scenario when the memory is allocated using this function.

Hi Mike,

I understand that such Applications require large amount of memory, but there should be some upper limit.

As I see in current phmupdf is that on scrolling operations on high zoom level the memory usage keeps on increasing and never stops until my application crashes.

Really, I do not know. As far as I remember upcoming mupdf 1.2 has some improvements regarding memory usage, but I would not have entertained little hope. 30Mb is a very good memory usage for such kind of applications like PDF reader.

Hi Mike,

Thanks for the inputs.

I tried the options as cache size reduced to 8 MB and

PHMUPDF_RENDER_MAX_IMAGES 4 and also reduced anti-aliasing to 4.

However I can still see a total memory usage upto ~30 MB on zooming and scrolling operations.

Can the memory usage of the application be further reduced as our system is supplied with low memory. Can it be restricted to ~20 MB max.

There no memory leaks, as far as I know.

PhMuPDF consumes about 256Mb of RAM for cache, you can change this value in the main() function of phmupdf.c module:

application.settings.cache_size=FZ_STORE_DEFAULT;

FZ_STORE_DEFAULT is equal to 256Mb.

Also you can change PHMUPDF_RENDER_MAX_IMAGES macro in the phmupdf.h module. Default value is 16, so 16 offscreen/memory contexts will be used to hold 16 pages of document, usually adjacent or last viewed pages. Minimum value is 4. Each cached page can consume 4-8Mb depending on size of PhMuPDF window or zoom value.

Kapil Gadgil(deleted) — Tue, 22 Jan 2013 09:55:22 GMT

I am able to use Phmudf with generic source 1.0 dowloaded from http://code.google.com/p/mupdf/downloads/detail?name=mupdf-1.0-source.tar.gz&can=2&q= and the phmupdf source code provided by you.

However phmupdf consumes a lot of heap and shared memory on scroll and zoom operations.It may be a possible memory leak.

Are there any possible fixes for these in generic muPDF1.1 or there may be some other reasons.

post98633: QNX Photon grid/table widget

Jaroslav Rab — Thu, 17 Jan 2013 14:06:21 GMT

I need a grid-like widget containing "inside" widgets (PtButton, PtText, PtToggleButton, PtNumericFloat or PtNumericInteger), with column resizing by dragging with mouse. These inside widgets should have uniform heigh and widgets in the same column should have the same width. Any of these inside widgets can get focus at any time (e.g. by clicking on it with LMB). There shall be possibility to remove and add the "inside" widgets (thus I can simulate row manipulation).

I tried to implement this behavior using different methods provided by Photon API, but without any luck. I've tried to use anchoring, different containers (PtDivider, PtContainer, PtScrollContainer, PtGroup) and layouts. I've figured, layouts are probably working only in PtWindow; resize policies do not work in nested widgets (neither for parents nor for childs) and the only possibility to display nested widgets is to specify a fixed size which is of course unusable for my purposes. I know, PtScrollContainer needs to know from its childs their size, but it does not work either. It is apparent, the "PtDivider in PtTree" solution does not suffice because of the need to use different widgets inside different grid cells (and not only text separated by tabulator characters!).

The following code demonstrates the latest attempt to acomplish a grid-like widget. I'd like to use the grid-like widget in my final application just as is shown in this demo (i.e. nested in a PtContainer which is a direct child of PtWindow). If I try to use e.g. "PtGroup" instead of "PtContainer with Pt_LAYOUT_VERTICAL", the buttons don't get resized (they both don't fill the available width and don't allow the PtDivider to resize the column width). I've tried to accomplish the widge using PtGridLayout instead of PtRowLayout, but the result was the same as with PtRowLayout (i.e. no widgets displayed).

Any help would be much appreciated.

Hi Pablo,

You can find the information I am about to discuss at the following URL:

http://www.qnx.com/developers/docs/6.4.0/photon/widget_ref/ptraw.html

After reviewing, and fixing the test case to compile, there were several drawing issues that needed to be addressed to avoid tearing, and or flickering.

1) Set the repeat value for the PtTimer widget

2) Removed the call to RRender() from the PtTimer tick handler callback.

3) Integrated the RRender() call directly into PtRaw draw_f() callback.

4) Implemented proper canvas calculation and clip rectangle setting in PtRaw draw_f callback.

After these issues were addressed, I changed the code to update the float numerical value in the PtLabel on every draw pass, to simulate draw updates.  I also modified the coordinates of the polygon draw, so that a simple animation would occur.

We tested the new code on a Pentium D processor with the vesabios, and svga driver, and did not witness any tearing or flickering.  The main issue with the original version of the code, was drawing outside the draw scope of the PtRaw draw flow (calling RRender() from tick handler).

Try the modified test case (see attached), and determine if it flickers on your target setup.  If no flicker is witnessed on your target setup with the modified test case, please modify your code to follow the sample coding principals.  If you still encounter flicker after updating your application, change the test case to more truly represent your application.

Regards,

Derek

post97178: Custom container widget crashing Windows hosted PhAB

David McMinn(deleted) — Wed, 14 Nov 2012 13:31:16 GMT

Hi,

I am trying to create a custom container widget (subclassed from PtContainer) and find that it crashes PhAB when hosted under Windows. I'm using QNX 6.5.0 SDP on Windows 7 Pro x64. My target is x86 and for testing I have VirtualBox running with QNX installed from the SDP CD.

I have managed to create a custom widget subclassed from PtBasic in the past and have been able to add it, set resources and see the live widget display and am following pretty much the same procedure. I could only find cygwin 1.5.25 to install, which is different from the one supplied with QNX (1.5.24). It stops me being able to use cygwin's bash at the same time as PhAB but I don't know if there any other conflicts.

Now I am trying to create a custom widget subclassed from PtContainer and am going through the help as I do it, but in order to get some confidence I have done only the minimum (I think) I need to get a custom container going. I've attached the source here but there is basically only 1 new resource, I override the defaults function and no others. After I build, make the DLL available on my path and add the definition to PhAB I try to use it. I select "Add Widget Class..", which then prompts for the class. Enter that, PhAB finds it as it says it is going to add a widget of class <name> to my base window and when I click on continue it crashes.

Are there any hints on how to track down what is causing this crash? The output on PhAB's console window doesn't say anything. Are there any functions I must provide for a custom container widget?

I know this has no bearing on the correctness of my code but I am able to built the custom widget for my target, add it to the self hosted PhAB and use it without crashes. Whether there is some stray error in my widget code that causes Windows PhAB to crash but not QNX PhAB I don't know.

Thanks.

Pablo Cepedal — Tue, 13 Nov 2012 19:13:57 GMT

Derek, first of all, thanks again for all your help.

I'll try to make a self-contained example of what I'm trying to do.

It's a bit complicated because I'm trying to reuse an application we've already made without PhAB.

The critical part of the application updates its state using messaging with some existing modules and updates an image every 200 ms.

This image is the same size of the full screen, 640 x 480 and on top of that we need to have some indicators, such as labels that also update their value every 200ms.

The app needs to run on an embedded AMD Geode LX-800 chipset with a 640 x 480 screen, 256Mb RAM and 1Gb EEPROM.

I'm developing on a PC with ASUS MB, AMD Sempron processor and 512Mb RAM running QNX 6.4.1 with svga drivers.

I think it's because of my bad english that "flickering" may not be the most accurate term for what I see on screen but it's the closest word that I know for that but I don't know the exact meaning of "tearing".

I've attached the .tar file with the basics of the project.

Thanks in advance.

Hi Pablo,

We would like a self-contained test case, that we can compile. It does not need to be your exact code, just something that represents it.

It is quite possible that "tearing" will occur, with an unaccelerated driver, but we would be surprised if there was flickering.

If you can send us the test case that we can compile and run, we will give the best solution we can think of.

Regards,

Derek

Hi. I've tried reparenting the labels into PtOSContainer but I can still see the screen/image sweeping.

The app is something like this:

1) A window created in PhAB that contains:

- PtOSContainer

- PtRaw (PtOSContainer's child)

- PtLabel (PtOSContainer's child)

2) A timer_cb that ticks every 200 ms. This cb does the following:

2.1) Updates the app state (data input).

2.2) Render function (that makes conversions from data input (GPS) and screen)

This function makes some calculations and uses the Photon primitives:

First:

// Fills a rectangle the same size of the screen with a certain color

PgSetFillColor();

PgDrawRect(r, Pg_DRAW_FILL);

Then:

// Draws the polygons and lines needed.

PgDrawPolygon()

PgSetStrokeColor()

PgDrawLine()

...

2.3) Damages the PtRaw widget.

3) The draw_function that runs with every PtDamageWidget() does this:

3.1) Sets the label's text with: PtSetResource(ABW_speed_label, Pt_ARG_TEXT_STRING, speed, strlen(speed));

3.2) PgDrawPhImage(&pos, VidImg1, NULL)... where:

- &pos is a PhPoint_t {0,0}

- VidImg1 is the image that was formerly modified with every 200 ms loop in PmMemoryContext_t and flushed into the PtRaw widget.

The idea of this is to show some GPS map (along with some other data, generated in item 2.2) and to put some controls and labels on top of that graphic.

Please let me know if this is enough or if you need some more details/code.

Thanks for your time.

Hi Pablo,

The buttons would also need to be parented to the PtOSContainer:

PtOSContainer <--- PtRaw

<--- PtButton's

6.5.0 also contains single-pass rendering, which provide better performance.

The problem is, that SVGA and vesabios drivers do not provide offscreen memory, and your NVidia chipset does not have an accelerated driver to take advantage of this.

Please parent the buttons and labels to the PtOSContainer as well. If there is no improvement, please post a simple test case for our review, that demonstrates the problem.

Regards,

Derek

That's the way I did before, but it didn't fix the problem, I gues because I was still using PmMemoryContext_t. I'm trying with PdOffscreenContext_t and it seems to help with the flick in the label widgets but now the PtRaw widget started blinking. I guess it still needs some workaround migrating from PmMemoryContext_t to PdOffscreenContext_t.

Misha, I've tried putting the raw widget inside a PtOSContainer but the widgets still flicks.

I'm using a PmMemoryContext_t to do the offscreen drawing with

PmMemStart() and PmMemStop() and flushing it into a PhImage_t.

The draw function of the raw widget uses PgDrawPhImage to flush the image into the widget and sets the new values of the label widgets with PtSetResource.

I've also tried with PtHold() and PtRelease() but that didn't work either.

Is there any other workaround? Am I missing some PtOSContainer operation?

Thanks again.

Hi, i'm new to Photon developing and I have a problem with my app.

I'm using a PtRaw widget to display some graphic made with Photon functions such as PgDrawPolygon, etc. The raw widget is damaged (and therefore, redrawn) every 200ms with a timer_cb. The raw widget's width and height is the same as the app window.

On top of the raw widget there are some other widgets as labels that update their value every 200ms too.

The problem is that those labels that have rectangular borders are ok but those that have an image background (Pt_ARG_LABEL_IMAGE) or rounded borders (Pt_ARG_HIGHLIGHT_ROUNDNESS) flick when the raw widget beneath them damages.

I've tried to fix that by changing some flags but didn't get anywhere.

I'm trying to work it out using layers but I don't know if that's a possible solution. Is there any other way to avoid this? If it is, how can I know if my HW supports layers?

Thanks in advance.

KB(deleted) — Fri, 02 Nov 2012 22:22:44 GMT

Hi,

I would like to know if there is a flag to set or maybe a function to call in order to display the scale on a trend graph grid?

If not what are my options? (labels, raw widget, ... ?)

My final goal is to display a spectrum of 1024 samples with zoom capability.

Besides, I would like to add vertical and horizontal cursors on the trend too and to display the coordinates of each sample when I put the cursor on the spectrum.

I guess the trend widget does not fit my goal (I blow my mind to try to zoom on the X-scale! ) and that I will have to code my own widget in order to achieve that :|

Or maybe with a raw widget and few functions such as PgDrawTrend], PgDrawPixelArray, PgDrawPolygon and so on ...

What do you think about it ? I'm a little confused here

Any tip, link or snippet of code would be appreciated!

It works for me on 6.4.1 and 6.5. But I think it must be re-complied under 6.4.0 to get it working. GUI of the reader uses alpha blending for icons to show soft shadows under the picture. Looks at the bottom of gear icon, for example. I do not remember if 6.4 supports alpha blending through the PhImage_t settings or not.

If you are still experiencing problems with building, I uploaded 1.1 version to github and you can obtain generic 1.1 version at http://code.google.com/p/mupdf/downloads/detail?name=mupdf-1.1-source.tar.gz&can=2&q= and then we will try to compile it at both sides step by step.

If you have noticed, the archive mupdf-1.0-src.tar.gz as well as mupdf-1.1-src.tar.gz contain 3rdparty directory, which has headers and pre-compiled static libraries of all things, which are required to build phmupdf on QNX:

libz.a

libpng15.a

libopenjpeg.a

libjpeg.a

libjbig2dec.a

libfreetype.a

libbz2.a

Final phmupdf binary only depends on:

1) libph.so.3

2) libm.so.2

3) libc.so.3

4) libfont.so.1

which are all QNX system libraries, available even in runtime only installation.

How phmupdf binary was copied to this machine ? If through the network, like FTP, please make sure that binary transfer mode has been enabled before.

Could you check checksum of both binaries with cksum utility: "cksum phmupdf"?

Hi,

You have to obtain generic sources for mupdf at http://git.ghostscript.com/?p=mupdf.git;a=summary , please use version 1.0, not latest sources. Or just download 1.0 snapshot at http://code.google.com/p/mupdf/downloads/detail?name=mupdf-1.0-source.tar.gz&can=2&q= . Extract my sources to the directory with mupdf sources. Type "make -f Makefile.qnx". Enjoy.

Hey Derek,

I know it's been a while, but I did get my first experiment protocol running using the PtTimer. It's accurate to about 2 ms, which isn't bad at all.

I was wondering, though, if, now, you could please show me just a simple example of using RtTimer (RtTimerCreate and RtTimerSetTimer).

post94564: Data entry verification

Frank Applin — Wed, 01 Aug 2012 15:33:21 GMT

Hi,

I have several text fields on a dialog that I have to ensure are all filled in. I would like to check them all in the Done callback (when they click on a Done button). I will display a message informing them of what needs correcting.

I don't see how you can keep the dialog from closing, though. I see an example of preventing someone from closing via the menu or 'x' button (and if they do want to close - it exits the application - not just the dialog).

So, can someone help with this?

It is the Advance Graphics Framework APIs. It is low level draw API calls, and is more synchronous in nature (no main loop).

OK, if you want it all in one app, then get it up and running with PtTimer, then recode to RtTimer.

The only reason I am suggesting to use the PtTimer first, is because it is easier, and you can work out all the logic first.

Hi Derek,

First, thank you for taking your time to be so helpful. These are going to need to be accurate to within a few milliseconds. The caveat that I don't know if I mentioned in a previous post or not is that before and after the image is displayed I will be sending a short pulse to a parallel port line connected to a PC running EEG software. So, if an image is displayed for 2025 milliseconds - we want to be able to look at the EEG between the parallel port pulses (called events in the EEG world) and hopefully it's damn close to 2025 milliseconds. Does that answer your question?

Derek Leach — Sat, 28 Jul 2012 02:19:15 GMT

How "accurate" do you need? I understand your requirement for the delays, but how close to these delay values is necessary?

PtTimer in most cases is feasible.

I would get it all running with a PtTimer, with a fine repeat, then check in the callback against your delay values, and decide whether to swap the image or not.

It will not be a waste of time, as you could reuse a lot of the code with the RtTimer, if it is really necessary.

I guess this comes down to a design question then.

Should I be displaying the images (I'm assuming using RtTimer because I need accuracy) in a separate thread, in background process, in work procedure, or in some other method that I haven't read up on, yet?

A user will basically be clicking on a Start Button of a simple dialog to open this new dialog that displays the images for the staggered amount of times (read in from the file and stored in some global structure at the start of the application).

You want:

PtSetResource(ABW_PtTimerImage, Pt_ARG_TIMER_INITIAL, 5000, 0);

And if you want a repeat:

PtSetResource(ABW_PtTimerImage, Pt_ARG_TIMER_REPEAT, 5000, 0);

In the lines below you are setting the callback resource to reference the PtCallback_t pointer (void *)Pt_TIMER_INITIAL, which is just a number constant, which causes the crash.

Hi Derek,

I hate to ask such basic questions, but the documentation is seriously lacking in example code.

I created a base dialog with a PtTimer and a button on it.

PtTimerImage has an initial value of 0 and a repeat value of 1. The Activate callback is called DisplayImage (just using printf(), now).

PtButtonStart has an Activate callback named StartTimer.

What I am trying to accomplish in this little test program is that when I click the Start button, the timer's initial value is set to 5000 which should then call the DisplayImage callback (if I'm understanding this correctly). In the DisplayImage callback - I want to display the time of day and re-set the initial value of the timer to 1000.

So, the code for the StartTimer callback looks like:

PtSetResource(ABW_PtTimerImage, Pt_CB_TIMER_ACTIVATE, Pt_TIMER_INITIAL, 5000);

The code for the DisplayImage callback looks like:

printf("here\n");

time_of_day = time(NULL);

printf("It is now: %s\n", ctime(&time_of_day));

PtSetResource(ABW_PtTimerImage, Pt_CB_TIMER_ACTIVATE, Pt_TIMER_INITIAL, 1000);

It builds fine and when I run it from a terminal console - the dialog appears, I click Start, and I get a memory fault.

Can you help starighten me out, please?

Steve Reid(deleted) — Thu, 26 Jul 2012 19:43:33 GMT

I'm a bit rusty on Photon, as it's been a while since I worked on those docs. If you call delay() or something like that in a callback, you're delaying the processing of events by PtMainLoop(), which isn't a good idea, as your entire program--including the processing of mouse buttons, the refreshing of windows, and so on--is delayed. PtTimer and the RtTimer* functions work correctly with the event loop. As I recall, the inaccuracy can happen because the expiry of the timer joins any other events that are already in the event queue.

If you're doing a simple animation where the delays are in seconds, PtTimer is probably good enough. If you need hard realtime, especially with very short delays, you need to use a timer in a separate process that doesn't use the Photon event loop.

You can change the delay by resetting Pt_ARG_TIMER_INITIAL to the next delay, in the timer's Pt_CB_TIMER_ACTIVATE callback.

Some of the people who are monitoring this forum know this stuff a lot better than I do, so I hope they'll correct me if I got something wrong.

Thanks, guys. I am really new to this (just installed Neutrino, yesterday) and this isn't your normal C/C++/C#/Java event handling coding. So, let me look at the PtTimer and try to absorb what you are talking about.

Derek Leach — Thu, 26 Jul 2012 17:58:04 GMT

Ok, the key is that the Photon processing is not immediate in the callback versus what you see on the display, so if you set image1 then image2, you will only ever see image2.

You never want to stall out in the middle of a callback.

What you want to do is of a rather synchronous nature, with non-equal delay time.

With a Photon app the PtMainLoop() is already running.

There are more hacker ways of going about this, but could you try setting the PtTimer to a really fine repeat, then check your delays in there?

If not, I will have to think about this for a bit.

What I am after is to be able to read a simple text file that has bitmap names and timings (usually in ms). This kind of stuff is done in psychology experiments with EEG. You show an image for a period of time and delay. Move to the next picture with a new period of time (just slightly staggered) and delay. And it keeps doing this process all the way through the file.

So, the text file might look like:

beagle.bmp, 2000

blank.bmp, 2000

canary.bmp, 2015

blank.bmp, 2000

beagle.bmp, 2045

I think Derek's suggestion is just right. Set the PtTimer interval to 1ms or so; checking a delay count doesn't generate so much overhead.

Try to pre-load the images and delay counts when starting your application (or when opening the definition file).

And it keeps doing this process all the way through the file.

So, the text file might look like:

beagle.bmp, 2000

blank.bmp, 2000

canary.bmp, 2015

blank.bmp, 2000

beagle.bmp, 2045

blank.bmp, 2000

canary.bmp, 2065

blank.bmp, 2000

beagle.bmp, 2100

blank.bmp, 2000

post94436: Re: RE: How to swap images using a label

Would I be able to change the timer to something that is not a set time?

Derek Leach — Thu, 26 Jul 2012 15:57:56 GMT

Setup a PtTimer that checks a "image index" ... after the callback for the PtTimer fires, check the "image index" for what image to display, and set the Pt_ARG_LABEL_IMAGE with that image, then change the "image index".  The next time the PtTimer fires, your "image index" will be different, so you would set the other image to the label.

Preload the image (PxLoadImage) in an application startup callback, you do not want to keep reloading the images -> slow, and if you do not release, leads to memory leak.

Subject: How to swap images using a label

Hi,

I'm new to QNX and PhAB, but have been programming for 20+ years. I guess I'm most familiar with the Visual Studio paradigm.

I am using Neil Carter's example of showing an image using a label.

int ShowImage( PtWidget_t *widget, ApInfo_t *apinfo, PtCallbackInfo_t *cbinfo ) {



   PhImage_t   *myImg;

   char        myImgFlnm[20] = "PICTURE.BMP";

   /* eliminate 'unreferenced' warnings */

   widget = widget, apinfo = apinfo, cbinfo = cbinfo;



   if ((myImg = PxLoadImage( myImgFlnm, NULL)) == NULL) {

      fprintf( stderr, "Error loading image file %s\n", myImgFlnm);

      PtExit( EXIT_FAILURE );

   }

   PtSetResource(ABW_lblMyImg, Pt_ARG_LABEL_IMAGE, myImg, 0);



   return( Pt_CONTINUE );

}

How can I swap out the current image with another image after a short delay?

I tried the following, but it simple shows the 2nd image:

int ShowImage( PtWidget_t *widget, ApInfo_t *apinfo, PtCallbackInfo_t *cbinfo ) {



   PhImage_t   *myImg, *myImg2;

   char        myImgFlnm[20] = "PICTURE.BMP";

   char        myImgFlnm2[20] = "PICTURE2.BMP";

   /* eliminate 'unreferenced' warnings */

   widget = widget, apinfo = apinfo, cbinfo = cbinfo;



   if ((myImg = PxLoadImage( myImgFlnm, NULL)) == NULL) {

      fprintf( stderr, "Error loading image file %s\n", myImgFlnm);

      PtExit( EXIT_FAILURE );

   }

   PtSetResource(ABW_lblMyImg, Pt_ARG_LABEL_IMAGE, myImg, 0);

   delay(5000); /* delay 5 secs */

   if ((myImg2 = PxLoadImage( myImgFlnm2, NULL)) == NULL) {

      fprintf( stderr, "Error loading image file %s\n", myImgFlnm2);

      PtExit( EXIT_FAILURE );

   }

   PtSetResource(ABW_lblMyImg, Pt_ARG_LABEL_IMAGE, myImg2, 0);



   return( Pt_CONTINUE );

}

Thanks,

Frank

post94380: Sample code to blit to/from PmMemoryContext_t to/from PdOffscreenContext_t

Derek Leach — Mon, 23 Jul 2012 13:40:38 GMT

The documentation if wrong for PgContextBlitArea*(). One cannot blit to/from any other than a PdOffscreenContext_t with that routine.

Attached is code that uses GF to blit to/from PmMemoryContext_t to/from PdOffscreenContext_t.

There are three routines:

blit_init()

blit_deinit()

blit_dc_to_dc()

It does not necessarily perform an accelerated blit, but exposes the capability of the chipset currently in use.

post94345: RE: Transparent Photon background

Derek Leach — Thu, 19 Jul 2012 17:46:05 GMT

I have not done this approach lately, but try these suggestions. You could set the fill colour to Pg_TRANSPARENT, unless you are using a PtOSContainer. If you are using a PtOSContainer, set the fill colour to something not common, then set the chroma on the layer to that value, and no draw.

Subject: Transparent Photon background

Is there any way to have Photon's background either not be drawn, or drawn as "transparent"?

I'm trying to render some graphics on layer 0, and have some Photon objects overlay them, with Photon on layer 1. The problem is, Photon draws a background which totally obscures what's rendered on layer 0.

Thanks!
