explicitly paint to see effect of shader change #343

Closed pkarasev3 closed 7 years ago

pkarasev3 commented 7 years ago

At least for me on windows 10 with either OpenGL 3.x or 4.x, the window did not get updated until dragging off-screen or minimizing. Explicitly calling paint() remedies this; the window changes shaders instantaneously on F5.

I think there is actually an error. However, your code immediately requested a redraw. I implemented a version that uses the updateGL member function of the superclass that post a repaint event on the event queue. I'm not sure which of both is the preferred behavior, but can you test if my fix also works for you?

Looks good, I'll merge it. Thanks for contributing.
