Hi!

Thanks for your response.
I am not quite sure if I understand you correctly but here is what I tried:


- Calling the whole code (starting the NSAnimation and the ProgressIndicator animation) using a performSelectorOnMainThread does not fix it.
- Calling the whole code using performSelector delayed does not fix it.
- Calling the NSProgressIndicator startanimation alone on the main thread does not fix it either.


However your response triggered an idea and this works:

[myViewNSAnimation startAnimation];
[myindicator performSelector:@selector(startAnimation:) withObject:nil afterDelay:1.1];


Does the trick, but only if the delay is greater than the duration of the NSAnimation.
In short, if I call the selector (even on the main thread) during the NSAnimation is running, it does not work.
That would make some sense - but why the same thing works without those tricks in awakefromnib does not make sense to me...
Because I would think that running it in awakefromnib and running it using performSelectorOnMainThread should be somewhat identical?


While it is great that I have a workaround ... I would appreciate any explaination on why it behaves that way.
Technically this does not make sense to me.


Cheers
Thomas

Further to my below question I found out that the problem is related to what is triggering the code that starts the animation:
If the code that starts the NSAnimation and the NSProgressIndicator animation is called in an IBAction called by a button on a different window,
the NSProgressIndicator animation does not start.

Try scheduling a delayed perform in a normal runloop mode. The button is probably implementing its own runloop (one of the two ways controls perform mouse tracking). You need to break out of this runloop mode, and peformSelector:onMainThread: will do it.
