Question

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 ?

Answer 1

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.
