[Qt-interest] [Qt-nterest] Qt::WA_OpaquePaintEvent on OSX

[Martin Guillon]

I tried 
WA_StaticContents
WA_OpaquePaintEvent
WA_NoSystemBackground

I the 3 cases the all frame is erased under OSX. I really need that to do a really good pen drawing application.

Can someone help?

Thanks

Now I did and It doesn’t work.
With that flag my frame is transparent (something I want to) but the StaticContent doesn’t seem to work under osx (qt-carbon) and I really really need it. 
To give more info I am doing a qt application to draw on the desktop.

Have you tried setting Qt::WA_NoSystemBackground?
