Hi all,
I’m attempting to use the QGLPainter from Qt3D with Qt 5.4’s new QOpenGLWidget
- I was originally making do with QGLWidget from the previous Qt version but I
was running into trouble with putting widgets, buttons, etc. on top of the GL
widget, which is something I need to do. I’m fairly familiar with the Qt3D
library but not so much on the in-depth side, and right now if I call begin()
on a QGLPainter I create in the QOpenGLWidget’s paintGL() function, I get the
following messages output before the program crashes:
Attempt to cast non-window surface
Attempt to activate GL window surface on bad context
I’ve tried various things - calling begin() and passing the widget’s GL context
doesn’t have any effect, and the function won’t accept the context's QSurface
as it’s expecting a QGLSurface. Is there any way to get QGLPainter working with
the new QOpenGLWidget, or will I have to stick with QGLWidget?
Thanks.
