OpenGL draws widgets in Qt

Question

I am developing a Qt application that uses Cocoa on Mac and uses the PowerVR SDK to enable OpenGL ES 2.0 on Mac Desktop.

I managed to make it work, everything works fine, the problem is that when I create a widget in this window, OpenGL displays it, for example, I create a QLabel and it displays it, making the label invisible.

I tried calling the QLabel repaint () method after rendering a single OpenGL frame, but that didn't help.

Has anyone come across this or similar problem and have any suggestions?

Thanks!

If you want widgets to interact with OpenGL content, you should use QOpenGLWidget . It accesses the off-screen buffer, which is then compiled with widgets.

As an alternative, you yourself must visualize the label in the texture and apply the texture to the square.
