You don't need to subclass anything just to draw into an NSImage. You can call an NSImage's -lockFocus method to direct all the usual drawing functions and methods to draw into that image, instead of into an onscreen view. Don't forget to call -unlockFocus when you're done! So, what you want to do is, get the default image, -copy it and -autorelease the copy, send the copy a -lockFocus, draw whatever content you want to add to the icon, using all the usual functions & methods you'd have used in a subclass' -drawRect: method, send the copy a -unlockFocus, send the copy to -setApplicationIconImage:. sherm-- -- Cocoa programming in Perl: http://camelbones.sourceforge.net _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
