Hmm, perhaps I should have phrased this more as a question. But, I've
searched the net for several days and haven't found a single post with
anybody talking about this particular concern with Swing.
The importance of this feature becomes obvious with certain scenerios.
Assume you have a basic GUI with a toolbar, JTree and JTable. The
toolbar has a delete button. The delete button can be used against a
node in the tree, or a row in the table, depending upon which
component has focus. You are really going to mess with the user's
head if you can't show a visual cue to indicate which component (the
treel or table) has focus.
Any feedback on how to accomplish this in an elegant fashion would be
appreciated.
