What about Custom OpenGL Controls.


Message 1 in thread

I'm going to create some application with effect-rich controls. Refflections, 
Blends, Item-Zoom, etc. I have never do such things (just one with SDL), what 
about some examples or recomendations? Is OpenGL Controls the right way? Is 
there any examples of OpenGL buttons or something? Thank you, qt maillist!)

ÂDo you mean OpenGL Buttons emmbebed in the OpenGL window? ÂOr normal, let's 
say, QSliders are OK?

If the last option is OK, check:

I mean the way to modify buttons. I would like to get something like opengl 
button with matrix transformation on button itself when button pressed, etc.

Best example is macosx bottom application bar. What is the right way to derive 
QAbstractButton from QGLWiget (if it is the way to get opengl button)?

You might check out the MythTV frontend source code. They appear
render the application's entire Qt GUI (QPushButtons, QSliders,
QSpinBoxes, etc.) using OpenGL. I haven't  had time to evaluate it
fully, but it might at least give you some useful ideas.

I don't think OpenGL is *required*. Of course that's an option, but it should 
be possible to write a style that does not depend on OpenGL (just using 
regular QPainter calls).
