Method GTK2.Widget()->set_sensitive()

Method set_sensitive

GTK2.Widget set_sensitive(int sensitive)

Description

Sets the sensitivity. A widget is sensitive is the user can interact with it. Insensitive widgets are "grayed out" and the user can't interact with them. Insensitive widgets are known as "inactive", "disabled", or "ghosted" in some other toolkits.
