Re: Adding design-time 'live' functionality to IB palette items

Thanks for the first bit of info - can you tell me if I'm headed down the
right path here?

- I now have an object implementing the IBEditors protocol (a NSControl
subclass).

- When I double click my custom object on a NSWindow template, I can tell
the IBEditor is activating (as a test it's drawing a simple rectangle around
the control). Strangely enough, it calls -(void)closeEditor when this
happens.

Using mouseDown: I can move the IBEditor (as well as the edited object), and
(I'm assuming) pass any clicks through to the object to modify the
attributes I want, and have the object reflect these changes.

- However, when I deselect the object, the IBEditor doesn't seem to remove
itself from the view - the rectangle remains.

Any more tips would be appreciated.

Thanks again,

Chris
