I did both!
I used a superview for the background image.
And I had to create subclasses of NSButton and NSPopUpButton for the
thin lines between the buttons (to separate them).
I'm not completely satisfied with the result yet. It seems that the
border-less NSPopUpButton draws the arrows right next to the far right
of its frame, causing the separator line to be drawn in contact with
the arrows. It needs some tweeking.
That is quickly done, just make the NSRect in which the cell is drawn
smaller:
- (void)drawRect:(NSRect)cellFrame {
// Draw the line
[[ NSColor blackColor] set];
NSRect frame = [self bounds];
NSFrameRect( NSMakeRect(frame.size.width-1, 0, 1, frame.size.height) );
// Draw the button
NSRect innerFrame = cellFrame;
innerFrame.size.width -= 5;
[[ self cell] drawWithFrame:innerFrameFrame inView:self];
}
The biggest problem now is highlighting, if I click a button, the
button background becomes white, not aqua blue.
Okay, I am not sure how to go about this. You could subclass
NSButtonCell and play around with the -highlight:withFrame:inView:
method. But I think it will not be very trivial to implement the
typical aqua semi-transparent blue glow. Maybe you can work with
exchanging the background image by a highlighted one?
Cheers,
Michael
