Oh, I just got it. You've been saying "precedence" and I just realized you meant "precedents". (I thought you meant something like behavior inheritance.) Before you use Photoshop or OmniGraphSketcher or anything else that has a similar palette system as a precedent, you need to be sure that you're trying to solve the same problem that those systems were designed to solve. That's what I was trying to direct your attention towards. > Right now I have 4 inspectors, it may go to 5 but thats about it.

The reason I ... er ... accused you of using a shortcut is that your proposed solution isn't really repurposing the minimize button (and, it could be strongly argued, shouldn't repurpose it). The shortcut comes from not paying to attention to the *accidental* geographic similarity between the minimize button and the control you had in mind. If you chose to implement this with custom code, then you'd have to deal with only the following: 1. Suppressing the NSPanel title bar (possibly not hard). 2. Handling dragging of a window with no title bar (not hard). 3. Drawing an alternate gradient to look like a title bar (not hard). 4. Providing an alternate close control implementation (not hard, and quite possibly shouldn't be the traffic-light-style red button anyway) 5. Providing your disclosure control (not hard). 6. Resizing the window when the disclosure control action is triggered (not hard). Well, that's all I can think of. If you really wanted to have this behavior, it doesn't seem hard to implement in a way that is only a few lines of code and doesn't abuse the frameworks. In fact, I'd start by looking into using NSOutlineView to get the collapsing appearance and behavior for almost free. But, really, be sure you know what problem you're trying to solve before putting a lot of effort into solving it. :) _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
