Graphics on different planes
Message 1 in thread
Hi Again,
I have a general Qt graphics question. In X11, you can draw to different planes. In OpenGL you can do the same (hence I assume you can do so in QtOpenGL (please correct me if I am wrong here). Am I correct that if you are *not* using QtOpenGL, that there is no capability to draw on different planes? I've looked through the assistant, etc and haven't found anything that discusses graphics on different planes & QPainter...
Can anyone with Qt graphics experience corroborate or expand on this?
Thanks much in advance,
Susan
