You could try substituting the windows content view with your own (the
content view is responsible for the window background pattern) and then
override- [NSView drawRect:(NSRect)aRect] method and use
NSRectFill(const NSRect aRect) to paint in you color containing an alpha
channel. You will probable have to call - [NSWindow
setOpaque:(BOOL)isOpaque] too. You can try using - [NSWindow
setBackgroundColor:(NSColor *)aColor] but my brief experiments with it
have not produced any results.
