What I want to do is modify the dock icon while the application
running. The only interface I can find to do this is
NSApp.setApplicationIconImage: , which requires an NSImage. I have no
way to get at the actual view being used to draw the dock icon, in
order to subclass it; I have to create a new NSImage somehow, and pass
that to setApplicationIconImage.
There has been some confusion in the discussion so far, most of it my
fault for using the wrong terminology by mistake. What I want to
modify is the dock ICON, not the dock TILE. The doc tile is the tiny
image of the application main window that appears in the dock when you
minimize the application. The dock icon is (usually) the regular
application icon, that appears in the dock when the application is
launched, and which you may have sitting there permanently for ease of
access to a commonly used application. There is an interface for
making run-time changes to the view used for drawing the dock tile;
namely NSDockTile.setContentView: , but I do not find such an
interface for the dock icon.
This discussion is in some jeopardy of ratholing into off-list topics
like proper use of the dock and what constitutes consistent user
interface behavior for application icons. Maybe we should stick to a
basic technical question, which is possibly of broader interest:
What is the Cocoa way to alter an NSImage
dynamically (or perhaps alter a copy of
an original image), at run-time, while
preserving as transparent any transparent
areas it may have to begin with?
The best I have got at the moment is outrageous hackery at the pixel
level in the bit map; there ought to be something better ...

Well, mea culpa, I have not been speaking clearly; what I want to
badge is not the dock tile but the dock icon,
Not sure I understand what you're talking about. Do you mean to modify
the application's icon even when it isn't running? There is no API to
achieve this at this time.
