[Qgis-developer] How to get renderComplete painter reference

[Mathieu Pellerin]

Anita, just saw you commited a fix. Thanks!

May I suggest a small improvement? You should calculate the time it took,
in ms, to render canvas and deduce that ms value from the
animationFrameLength ms value in your singleShot call:

QTimer.singleShot(self.animationFrameLength,self.playAnimation)

Currently if you have a 1000ms frame length and canvas rendering takes
500ms, each frame will last 1500ms. Deducing the 500ms canvas rendering
time from frame length will fix this.  If rendering ms > frame length ms,
that'd allow you to skip singleShot and render next frame immediately.

Cheers and thanks again.
