I have a question about enabling/disabling the standard 'cut/copy/paste/clear' menu items under the 'Edit' menu. If I have an application that has multiple windows, where one window supports 'cut/paste' and another doesn't, and I need to support desk-accessories that need the 'Edit' menu, what do I do? I don't want menu entries that are non-functional to be enabled. I have discovered how to determine that a desk-accessory window had been activated or de-activated, and enabled/disabled the menu items appropriately, but then I discovered that I had missed the case of the desk-accesssory being closed, while its window was active. I've probably gone down a blind alley, but could someone tell me the right way?

In MacApp we check for an active desk accessory after each event. You do this by looking at the window kind field of the FrontWindow. DA Windows have a negative window kind (it is the DA refnum). If FrontWindow returns NIL, then there are no windows open. -- Larry Rosenstein Object Specialist Apple Computer AppleLink: Rosenstein1 UUCP: {sun, voder, nsc, mtxinu, dual}!apple!lsr CSNET: lsr@Apple.com

The way I solved it, and I don't guarantee that this is the best way, is to keep an eye on the value returned by FrontWindow(). If it points to one of my windows that needs the Edit items or a desk accessory, I make sure that the Edit items are enabled. Otherwise, I disable the Edit items. Additionally, (insurance you know) I make a practice of enabling the Edit items before launching a desk accessory and checking FrintWindow() (oops, FrontWindow()) when Close is selected from the menubar. -- -- Dale M.
