Question

Currently I’m drawing an NSImage in a custom NSCell like so:

- (void)drawInteriorWithFrame:(NSRect)theCellFrame inView:(NSView *)theControlView {
    // roundedCornerImage creates a new NSImage with rounded corners, rather than clipping.
    [[anIcon roundedCornerImage:5] drawInRect:anIconBox fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1.0];
}

Very simply I’m wondering how to draw an image underneath it. On the iPhone, I would do this by using: CGContextSetShadow (currentContext, CGSizeMake(1, -1), 2); just before drawing the UIImage, but I’m unfamiliar with how to do it on the Mac.

Any pointers would be great.

Look into the NSShadow class. CGContextSetShadow also exists on the Mac, but it’s slightly more difficult to get your hands on the context itself.
