I want my window's background to be yellow (NSWindow->Hacks)
Why you'd want to do that, I don't know, but someone asked me how to turn the window background yellow. Since the window has a contentView NSView in it, this adds a category on it that draws the background with a transparent yellow. You also get the pinstripe effects. Just put this code anywhere.
@implementation NSView (BWYellowView)
- (void) drawRect: (NSRect) rect
{
NSColor *transparentYellow;
rect = [self bounds];
transparentYellow = [NSColor colorWithCalibratedRed: 1.0
green: 1.0
blue: 0.0
alpha: 0.333];
[transparentYellow set];
[NSBezierPath fillRect: rect];
} // rect
@end // BWYellowView
I have no idea how you colorize the titlebar.
