Re: [Qgis-developer] How to get renderComplete painter reference

I thought of it, but haven't implemented it yet since I would have to keep track of the rendering time. Please file a feature request so this idea does not get lost. I'm still looking for a solution to the main topic of this thread (painter refrence) because I think it could help solve the latest issue concerning the timestamp label.

Martin, Both those signals are the same and work the same. The newer .connect method is the better way. - Nathan On Mon, Apr 7, 2014 at 7:31 PM, Martin Dobias wonder...@gmail.com wrote: Hi Anita On Sun, Apr 6, 2014 at 6:08 PM, Anita Graser anitagra...@gmx.at wrote: I need the painter from the renderComplete signal?

This is what I did in python console: from PyQt4.QtCore import * class A(QObject): def __init__(self): QObject.__init__(self) def f(self, painter): import sys; sys.__stdout__.write(hello\n) a = A() iface.mapCanvas().renderComplete.connect(a.f) when moving the map, it will output hello to the system console from where I started QGIS... so problem is probably somewhere else, not with connection itself. Apropos does either connect actually return True? I have learned not to trust the return value of connect() at all, for example: QObject.connect(iface.mapCanvas(), SIGNAL(abracadabra()), a.f) True I'm pretty sure map canvas cannot do this kind of magic!

From what I could figure out so far, I only get the painter into playAnimation() if I do the following trick with lambda: QTimer.singleShot(self.animationFrameLength, lambda: self.playAnimation(painter)) But even then, the exported images are without label ...

Re: [Qgis-developer] How to get renderComplete painter reference
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. Math On 6 Apr 2014 23:08, Anita Graser anitagra...@gmx.at wrote: Hi, I need the painter from the renderComplete signal? Could you help me with the correct syntax?
