I'd like to act on -mouseDown when it occurs within the bounds of an
NSImageView, which is a subview of a transparent overlay child window. Some of
you may be wondering why I'm trying to do this so I'll try to explain that up
front. There are bugs in Snow Leopard regarding the use of Core Animation with
layer-backed views and NSOutlineView. In order to avoid these bugs, which I'm
told Apple will not be fixing for 10.6, I'm using a transparent overlay to do
the required animation and implement something like QuickLook or a preview
function.
I tried the following code but it resulted in really bad latency and coordinate
issues (I think) in the parent window's event handling.
#pragma mark - NSEvent Handling Methods
- (void)mouseDown:(NSEvent *)event
{
[self.parentWindow sendEvent:event];
#if 0
[super mouseDown:event];
[self.parentWindow removeChildWindow:self];
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
[self close];
}];
#endif
}
- (void)mouseDragged:(NSEvent *)event
{
[self.parentWindow sendEvent:event];
}
- (void)mouseEntered:(NSEvent *)event
{
[self.parentWindow sendEvent:event];
}
- (void)mouseExited:(NSEvent *)event
{
[self.parentWindow sendEvent:event];
}
- (void)mouseMoved:(NSEvent *)event
{
[self.parentWindow sendEvent:event];
}
- (void)mouseUp:(NSEvent *)event
{
[self.parentWindow sendEvent:event];
}
I'm thinking that the way I'm forwarding events to the parent is wrong. So I'm
looking for advice on implementing a proper mouse filter that can forward
events and generate the same result as if the event was originally sent to the
parent window.
