You can register to observe the accessibility notifications AXApplicationActivated and AXApplicationDeactivated. These require you to register to observe a specific target application. Therefore, in order to catch every application switch, use the NSWorkspace -activeApplication method to get the name of the current active application, register to observe when it deactivates, then when it does deactivate get the new -activeApplication and register to observe when it deactivates, and so on. See Apple's iChatStatusFromApplication sample code for Leopard to see exactly how to implement this. -- Bill Cheeseman - [EMAIL PROTECTED] Quechee Software, Quechee, Vermont, USA www.quecheesoftware.com PreFab Software - www.prefabsoftware.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
