Hello,
While using Qt3D I'm trying to separate as much as possible the scene,
rendering, and render window/widget. I'm not using Qt3DWindow, I'm using
my own widget/surface.
The thing is, when I'm deleting my widget, I'm not deleting everything
like in Qt3DWindow (scene, rendering, aspect, etc.).
But even if I'm setting a null surface to the rendering before
physically deleting my widget/surface, the surface is still in use in
the rendering thread : it crashes (on swapBuffers).
Is there a way to synchronize/wait for next frame with the render thread
so I can be sure that my widget/surface is not used anymore so I can
delete it freely?
I'm using Qt 5.9.3, c++, no QML, and I set an OnDemand render policy.
regards,
david
