How to scrub svg animation?

DDR0

Hello. Using PyQt, I have created a little rotating triangle svg, the source for which was stolen from MDN. I create it like so:

self.animWidget = QSvgWidget('assets/images/rotating-triangle.svg', self)
self.animWidget.move(200,300)
self.anim = self.animWidget.children()[0]
self.animTimer = self.anim.children()[0]
		
self.uiAnimateTriangle.clicked.connect(self.animateTriangle)

How do I scrub through it, ie, set animation speed to 0 and change the time in animation? Running the following gives very weird results:

print('cf', self.anim.currentFrame()) #Prints "cf 95280", OK…
self.anim.setCurrentFrame(10)
print('nf', self.anim.currentFrame()) #Prints "nf 180600", wtf.

In addition, setting self.anim.setFramesPerSecond(0) does seem to take, but it does not pause the animation. Calling self.animTimer.stop() seems to work, but I think it only is stopping the repaintNeeded signals from being emitted. When I emit them myself, the triangle is still animated.

I'd like to have a little animated focus ring around some of my widgets, but I'm not sure how to do this if I can't control the animations.

Thanks!

QSvgRenderer does not give you the ability to start/stop the animation. You can only control the frame rate.

BTW. what is the self.anim object? I don't see anything relating to it in documentation. I think you may be using some private APIs here.
