messagebox with force_front

QNX DEVELOPERS GUI Programming

Hello,

I am trying to make a message box appear over a background map that is redrawn by another process. I am using Photon 1.14.

The messagebox is a PtPane with some PtLabels in it.

I have managed to create a region whith PhRegionChange, setting the Ph_FORCE_FRONT flag and making the region opaque to the Ph_EV_DRAW event. This has the effect that there is not a hole in the background map which is not repainted.

The problem I am having now is to make my messagebox paint itself in this hole. I have tried call the PtSuperClassDraw method on the PtPane, but nothing happens.

Any ideas?

Can you put your MessageBox in its own window? If so there is some way to force this window to be ‘Always on top’. I think this was possible by setting Pt_ARG_WINDOW_STATE to Ph_WM_STATE_ISFRONT, but I’m not sure about this, however there IS definitely a way to achive this with some flag-settings.

Perhaps there is even a way to achive this with a PtAskQuestion sort of message box.
