Actually, I meant to suggest it was a *bad* idea to put the panel in the document’s windowControllers. That was on the assumption that the panel is app-global, but if you’re creating one panel per document, then I don’t see a problem. Since you’ve added the panel to windowControllers, it’s going to behave (in lifetime terms) just like a kind of document window. So, even though it doesn’t close the document, closing the panel will cause the panel to be removed from windowControllers and discarded. When the user redisplays the inspector, you’d have to create a new panel and panel window controller, and manually add it to windowControllers. (That’s not even a hacky thing to do. You just have to remember to do it.) Alternatively, you could have the document keep a separate reference to the panel window controller. Then you wouldn’t need to re-create the inspector later, but you could just add its window controller back into windowControllers and show the panel window again. Alternatively, you could arrange things so that “closing" the panel doesn’t actually close it, but rather just does an orderOut: on the window. Later, you can just show it again. A couple of things to pay attention to: — Watch the aesthetics of the timing of things when the document closes. If you mess around with the panel lifetime, it may stay visible for longer than you want. — Watch the Window menu’s window list. You probably want a customized menu item for the panel, and you want to make sure that the panel’s item appears then when and only when it looks right. (Specifically, you might want the panel item there when its document is frontmost, regardless of whether the panel is visible, but you wouldn’t want items for other document’s panels then. This is going to depend on what other menu items you have for hiding or showing panels. You may not want the inspector in the Window menu window list at all.) _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
