So, basically you're trying to write a GUI editor, like Interface Builder? In that case, I think what you'd really want to do is build your view hierarchy slightly differently. It's been a while since I tried writing a GUI editor in Cocoa, and I did half a dozen in Classic/ Carbon, so I may be mixing up things here, but there are several approaches, all of which might work depending on what you want to do: 1) Use NSImage and NSBitmapImageRep's -initWithFocusedViewRect: method to create a snapshot of each view. Then you can create a custom view for each view that draws such a snapshot, accepts clicks, draws a selected look, etc. 2) Wrap each view in a container view. I think there was some way to make a view get clicks before its subviews get them. That way, you can intercept the clicks and do something special with them when needed, and also draw a highlight to indicate a selection. Views are objects just like any other, so you can easily create a new one using alloc/initWithFrame:, then use addSubview to insert it in another view etc., and thus dynamically change the view hierarchy or even build a completely new one, without a NIB. Same applies to NSWindows.

Under graphically I mean for example zooming of some parts of the window or change colors and so on and also to preserve the funcionality of the original window. For example, if the Proxy Window displays a part of the original Window (on which there is a button) on the Proxy Window we still can use the "zoomed" button as it were the original one.

Of course, the further step would be to also pass events from the proxied window to the source one. Is this even possible? What are you trying to do? Usually, "content" translates to "model", "display" generally translates to "view", so according to the Model-View-Controller paradigm, you could create another instance of your controller that has its own copy of the views, but points at the same model, instead of forwarding events. That's one of the advantages of Cocoa's MVC design: If you separate the view and the model code, you can easily have several windows showing the same data. It's also more flexible than just duplicating a window and forwarding its contents, because it can be scrolled to a different location, can have a different toolbar collapse state, can be a different size etc. Cheers, -- Uli Kusterer "The Witnesses of TeachText are everywhere..." http://www.zathras.de ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
