I put several controls (button,textfield,...) in a NSBox. is it possible to disable NSBox that user can't access controls (means can't click on button or write in textfield)?
how about nsview ?
Or, if you have a custom NSBox, you can override NSView's -hitTest: (conditionally)
- (NSView *)hitTest:(NSPoint)aPoint {
if (!enabled) return nil;
else return [super hitTest:aPoint];
}
To stop the window from sending events to all your subviews.
To provide visual feedback, conditionally drawing some sort of overlay in the custom NSBox's -drawRect method would work.
