Click through NSView

Question

I have an NSView containing multiple subviews. One of those subviews is transparent and layered on top.

I need to be able to click through this view dow

Answer 1

Here's another approach. It doesn't require creating a new window object and is simpler (and probably a bit more efficient) than the findNextSiblingBelowEventLocation: method above.

- (NSView *)hitTest:(NSPoint)aPoint
{
    // pass-through events that don't hit one of the visible subviews
    for (NSView *subView in [self subviews]) {
        if (![subView isHidden] && [subView hitTest:aPoint])
            return subView;
    }

    return nil;
}
