[Qt-interest] qtopengl postredisplay?

[shuda Li]

Dear All,

I am currently trying to build an application using opengl in qt for which
accurate bufferswaps (one for every opportunity) is critically important.
Using glut, I can simply set wglSwapInterval(1); and use glutPostRedisplay
after calling glutSwapBuffers to call my drawing function again.
I have found the swapinterval setting in QT, but I am unable to have my
PaintGL called automatically, I have to use a timer which jeopardizes swap
accuracy (my framerate is not constant, i miss swaps sometimes).

Is it possible to have PaintGL called automatically, without a timer?

Best and thanks!
Shuda
