Header buttons and custom headers

Question

I created a custom title bar for the blackened NSWindow (style 0), so that I can make it disappear like in Quicktime X. The only problem is that the buttons do not respond to the mouse and mouse movements in the title bar can be combined with button clicks.

The full source code is here: https://github.com/iaefai/OrganicUI in the /ORTitleBar.m and ORWindow.m classes.

Buttons are standard for this method:

self.closeButton = [NSWindow standardWindowButton: NSWindowCloseButton 
                           forStyleMask:NSTexturedBackgroundWindowMask];

Then it is positioned:

[self.closeButton setFrame: __frame];

Then added to the header:

[self addSubview: self.closeButton];
