RE: Phindows refresh error
It's been a long time since I worked with Phindows/phrelay and offscreen containers... I know that Phindows keeps its
own copy of all offscreen display memory, and phrelay sends draw commands that act on this memory to each Phindows
session that is currently dittoing the main display. Whenever Phindows connects to an existing Photon session, the
display gets refreshed so that all the draw commands are re-performed to recreate the offscreen contents. Perhaps this
refresh is not working in this case?
For OSContainers to display properly in Phindows, no direct manipulation of the offscreen memory can be performed, i.e.
by getting a pointer to the offscreen memory. All draws must be part of the regular photon draw stream. This doesn't
seem to be the problem here because the undrawn contents look like regular widgets.
I'm assuming your PPC target is big endian. Can you try to reproduce this problem with an x86 target, maybe even using a
virtual Neutrino machine? If this only happens with PPC, then there could be an issue with the endian conversions that
Phindows does. The last offscreen endian problem I have notes on was back in 2008.

Max

Subject: Phindows refresh error
Targhet: Power PC MPC5121, QNX 6.5
Phindows (3.0.44) running on Windows terminal doesn't refresh same widgets on OSContainers that are instead refreshed on
display (800x480). This happen especially when Phindows is activated after the GUI photon application on targhet, and
windows (Dialogs) are moved from off-screen position to on-screen position.
Taghet phrelay activation on inetd.conf file:
"phrelay stream tcp nowait root /usr/bin/phrelay phrelay -x"
We tested many options available on Phindows settings without results.
See attachments.
Any ideas?
Thanks

Re: Phindows refresh error
I haven't worked with Phindows for a very long time. I will be interested to see what the others say.
