gf_layer_attach() failed !!!
Dear All,
Dear All,
I am new to qnx GF, I have read “Advanced Graphics Developers Guide.pdf” and trying to draw a rectangle on GF. I have
x86 target machine connected to QNX Momentics IDE 4.7.
gf_layer_attach() is failed... can some help...
find output and code below.
Output:

Re: RE: gf_layer_attach() failed !!!
Return Value = 0x8
which is GF_ERR_INUSE..
I have installed qnx on i5 intel machine....and i can connect to it and run basic hello world...
i can use web browser too.

What else is running on the machine? Is Photon running? You only have one layer on your machine, so no other graphics
environment or application can be running.

What else is running on the machine?
I have a default installation and basic GUI is running.
…......
Is Photon running?
Yes.
176152 1 /photon/bin/Photon 10r RECEIVE 1
…......
Number of displays: 1
Display 0: 1024X768, refresh = 60Hz
Number of layers: 1
…......
I am very new to QNX, but I am experienced in linux application and kernel development.
Currently I am using intel HD Graphics, PCI device, Vendor ID:8086, Device ID:0152.
….
please suggest what I need to draw a rectangle or circle or line.
Below is list of all the process running. Result of pidin command.

If you want to use Photon, ypu must use Pg photon drawing lines, please see helpviewer in Photon.
If you want to use GF application, then you must exit Photon to text mode, then to make it easy, telnet into the QNX box
, then run the GF application.

Do let me also know how to toggle between GUI and text mode.
