Gtk# Mouse fuera de un widget.

[Phillip Neumann <phillip sofsis cl>]

Hola!...

Jugando con gtk#, me obsesione un poco, y quise hacer un tipico
"OnMouseOver" ala html/javascript.

No se me ocurre como implementar que la ventana popup se esconda cuando
el mouse no esta en el widget en cuestion.

En este ejemplo el widget es un TreeView.

Desde donde se podria esconder la ventana?


saludos!
