I’m porting a QNX4 1.14 Photon app to QNX 6.2.0.
The app consists of a base windows and 6 PtPanes
overlaid on top of each other, only one visible at
I have a PtTimer calling an update routine twice
per second, and it updates all of the widgets on
The problem is that it appears the widgets in the
lower PtPane’s are appearing to flicker “through”
the top PtPane. They are visible just for an instant
then disappear again.
This behaviour appears to be different compared to
How should I do this in order to avoid the problem?
(apart from marking which widgets are not part
of the top PtPane and then not updating those…)
Thanks in advance
