Make it a borderless window, set its window level to
kCGDesktopWindowLevel and make it clickthrough.

   NSWindow* window = [super initWithContentRect:contentRect
styleMask:NSBorderlessWindowMask backing:NSBackingStoreBuffered
defer:NO];

   [window setBackgroundColor: [NSColor clearColor]]; // transparent
window

   [window setAlphaValue:1.0];    // we want our drawings to be opaque

   [window setOpaque:NO];

   [window setLevel: kCGDesktopWindowLevel];

   /* carbon */
   void *ref = [window windowRef];
   ChangeWindowAttributes(ref, kWindowIgnoreClicksAttribute,
kWindowNoAttributes);
   // to reset: ChangeWindowAttributes(ref, kWindowNoAttributes,
kWindowIgnoreClicksAttribute);
   /* cocoa */
   [window setIgnoresMouseEvents:YES];


bye.  Andreas.
