OpenGL视口下的Qt对象

Question

I have just read here that "Qt transparent windows over an OpenGL viewport" :

But if I try to add some widgets (let's say a checkbox) over a frame, and via code, add a QGLWidget to this frame.. it does not render the widget.

How to achieve this effect? possibly keeping on using Qt Designer.

EDIT: due to the comment I have to specify that the problem I am experiencing is that every kind of widgdet OVER a QGLWidget seems not to be rendered anymore (because of some opengl context black magic?)

Answer 1

There's a good piece in the Qt Quarterly about how to do it: QQ: Accelerate Your Widgets With OpenGL . It does entail some large changes to move away from QGLWidget , but it seems reasonably straightforward to implement.
