Drag and drop widget

[AlannY <m alanny ru>]

Hi there.

I need an explanation about how to drag and drop widget. I saw a 
tutorial where one man shows how to transfer a text/plain data between a 
 CList (deprecated)... but I don't imagine how to transfer a whole GTK+ 
widget.

Should I destroy source widget and create exactly new in new place (like 
emulation "drag and drop") or you already have a "beauty" way?

P.S. tutorials wanted ;-)
