Hi,
I'm building a transparent interface, and I'm stuck at NSButtonCell.
An NSGradient with transparency is drawn in the cell. It overrides -
isOpaque to return NO. The gradient is drawn nicely from
drawWithFrame:, but if it's called from -highlight:withFrame:inView:,
the gradient is drawn on top of everything that's already been drawn,
resulting in an increasingly dark result when the button is pressed.
I feel I'm missing something fundamental here. I also hope that makes
sense to everyone.

- (void)highlight:(BOOL)flag withFrame:(NSRect)cellFrame inView:
(NSView *)controlView
{
if (flag) {
[self realDrawWithFrame:cellFrame inView:controlView
gradient:pressedGradient];
} else {
[self realDrawWithFrame:cellFrame inView:controlView
gradient:buttonGradient];
}
}
- (void)drawWithFrame:(NSRect)cellFrame inView:(NSView *)controlView
{
if (![self path]) {
NSRect roundRect = NSInsetRect(cellFrame, 6, 6);
roundRect.origin.y = roundRect.origin.y - 1;
[self setPath:[NSBezierPath bezierPathWithRoundedRect:roundRect
xRadius:roundRect.size.height / 2
yRadius:roundRect.size.height / 2]];
}
if ([self isHighlighted]) { // Handle keyboard equivalent
[self highlight:YES withFrame:cellFrame inView:controlView];
return;
}
[self realDrawWithFrame:cellFrame inView:controlView
gradient:buttonGradient];
}
