Re: [gtkmm] Change cursor in Widget

[Sergio Pascual <spr astrax fis ucm es>]

I have put the code inside on_realize, but it still segfaults. I have 
attached the code, it is a little bit more elaborated.

I have also searched "cursor" in the FAQ 
(http://gtkmm.sourceforge.net/gtkmm2/docs/FAQ/html/index.html) but it's 
not there
