hello.

I have a window with a custom view and 3 sliders. the view is assigned to a custom class which is a subclass of NSView. when I change the size of the window, drawRect: is called, the view displays its stuff, no problem there. but: I want the view to update when any one of the sliders is moved. how do I do that? I've tried [self setNeedsDisplay], but that didn't work. I tried [self display], but that didn't work either. so I tried both, but the view still refuses to update when i move a slider. What am I doing wrong?

Who is getting the action event from the slider? Is it actually getting it? You check using the debugger?

My custom class has 3 action methods, one for each slider. yes, they get called, and the variables are set. after that, [self setNeedsDisplay:YES] and [self display] are executed, but they don't have any effect.
