GtkMenuItem::deselect

deselect() makes the calling GtkMenuItem emit the "deselect" signal inherited from GtkItem.

In the GtkMenuItem widget, the emission of the "deselect" signal causes the widget to display its normal GtkStateType and pops down its submenu, if it has one.

Note that the "deselect" signal is also emitted whenever the cursor leaves the screen area of a menu item.
