Thanks for the info, I found the piece of code you were referring to,
but somehow I can't get it to work... here's my code:
- (IBAction)sliderMoved:(id)sender {
SEL trackingEndedSelector = @selector(sliderEnded:);
[NSObject cancelPreviousPerformRequestsWithTarget:self
selector:trackingEndedSelector object:sender];
[self performSelector:trackingEndedSelector withObject:sender
afterDelay:0.0];
// do whatever you want to do during tracking here
[self willChangeValueForKey:@"imageContrast"];
imageContrast = [sender doubleValue];
[self didChangeValueForKey:@"imageContrast"];
}
- (void)sliderEnded:(id)sender {
// do whatever you want to do when tracking ends here
NSLog(@"Done tracking");
}
My label is bound to imageContrast so that it is updated live....
right now I'm only trying to log a message when the tracking is
done... my slider is connected to the sliderMoved action... did I do
anything wrong? Right now when I move the slider I get a ton of "Done
tracking" messages in the console, and my label is never updated..
which is... well, almost the opposite of what should happen....

I was wondering if its possible to have an NSSlider send an action
after the user finished dragging, while still providing continuous
updates?
Look in the archives for the October thread named "notification of
NSSlider end of tracking".
