Problem: Port Qnx4->6.3 PtRaw functions

I am trying to port working Q4.25/photon 1.14 functions to Qnx6/Photon.
The use of the PtRaw widgets seem to have a different behavior under
6.3. All the draws to the PtRaw widget are done twice, sometimes more,
for what should be a single draw.
Is this a known problem?? The rest of the gui code works pretty well
with just resizing of fonts etc.

Thanks,
A.

Ann,

I may have a solution writing to shared memory
instead of PtRaw direct. I will try it and get back to you.

Somewhere in the docs it talks about the first rect in the damage list will always cover the entire widget followed there after by the actual damages. I remember using an example that tested for a second entry in the list before skipping the first one.

Found it in: Photon microGUI for QNX Neutrino → Programmer’s Guide → Raw Drawing and Animation → PtRaw widget → Using damage tiles

Thanks Evan, I’ll check it out.
