Dynamically updating application icon in OSX

Question

When I used Chrome to download something to Lion, an icon with downloadable progress is displayed on my dock, which is dynamically updated.

How can this be achieved?

Answer 1

I think you are looking for this piece of code:

[[[NSApplication sharedApplication] dockTile] setBadgeLabel:@"My String"]; 

Here you can find all the necessary information (this is an NSDockTile Class Link ).
