The Installer.app program has a cool looking transparency effect where
it has a slightly transparent white box, then the background image, then
finally the striped background of the window. How do I do this in
cocoa?
I started by sub-classing an NSBox and rewriting the drawRect function:
- (void) drawRect:(NSRect) frame
{
NSRect rect=[self frame];
[super drawRect:frame];
rect.origin=NSMakePoint(1,1);
rect.size.width-=2;
rect.size.height-=2;
[[NSColor colorWithCalibratedWhite:1.0 alpha:0.9] set ];
NSRectFill(rect);
}
However, the box does not end up being transparent. Instead it is just
off-white. Can someone point me in the right direction?
