Well, I tried setMiniwindowImage and it apparently does nothing - and the documentation says it works for "collapsed miniwindows", whatever those are :-), but not for dock tiles.

You need to set a default, which you can do in the context of your app by registering it at startup. From the AppKit release notes:

There is a user default, AppleDockIconEnabled, to enable setting the image in a minimized window tile with -[NSWindow setMiniwindowImage:]. The image will be scaled as necessary to fit the tile. This behavior is off by default, so you must set AppleDockIconEnabled to YES if you want to enable this behavior.

Ali, thanks and my apologies... I found your previous response (last month) to this same question only today.

However.

Drawing the window's image into a bitmap and then calling -[NSWindow setMiniwindowImage:] seems such a roundabout way to do this. After all, I just want to update my window's dock icon every couple of seconds when (for instance) a progress bar changes - not some arbitrary image, just the real window's contents!

OK, so I set AppleDockIconEnabled to YES. Then... someone suggested calling UpdateCollapsedWindowDockTile. So I went ahead and, into my NSWindow subclass, put:
if ([self isMiniaturized]) {
[self display];
UpdateCollapsedWindowDockTile([self windowRef]);
}
and... no effect at all. [self update] and [self flushWindow] also don't work.

It seems that Cocoa disables updating minimized windows somehow...
