NSImageView subclass that responds to mouse up and sends click event

BPImageView.h

@interface BPImageView : NSImageView
@property SEL clickAction;
@end

BPImageView.m

@implementation BPImageView

- (void)mouseDown:(NSEvent *)theEvent
{
    // see
    // http://www.cocoabuilder.com/archive/cocoa/115981-nsimageview-subclass-and-mouseup.html
    if (theEvent.type != NSLeftMouseDown) {
        [super mouseDown:theEvent];
    }
}

- (void)mouseUp:(NSEvent *)theEvent
{
    if (theEvent.type == NSLeftMouseUp) {
        NSPoint pt = [self convertPoint:[theEvent locationInWindow] fromView:nil];
        if (NSPointInRect(pt, self.bounds)) {
            [NSApp sendAction:self.clickAction to:self.target from:self];
        }
    } else {
        // this should never be called, but...
        [super mouseUp:theEvent];
    }
}

@end

Thanks for this!

I added this to make sure mouse events weren't firing on an image that wasn't visible:

if (NSPointInRect(pt, self.bounds) && self.alphaValue > 0.0) {
}

Pardon a dumb question, but where/how does one capture the sent click event? Should I be creating a clickAction method somewhere?
