My question is quite simple :

To use a custom menu for the apps icon on the dock, - (NSMenu*) applicationDockMenu: (id) sender; of the NSApplicationDelegate has to return the menu that the dock will display.

Using setImage on a NSMenuItem, you can normaly add icons to the menu. They show up on the normal menu, but not on in contextual menu of the app's dock icon.

Then how did Apple manage QuickTime, XCode, Preview to show icons in the list of recent opened files accessible in their dock contextual menu ?

Thx.
