I give you an example that I would like to have in emacs.

I wish to be able define a tab that does so:


1. at initialization it starts a grep and looks for something in background
2. The 'show event should commute to the buffer *grep*
3. when grep finds something, and the tab is hidden , the tab widget to
change the color
4. The 'close event should kill the *grep* buffer, and the process , if it
had not finished yet


 Could you do this using buttons in toolbar or menubar, as you insist ?
