GtkWidget::unmap

void
unmap (
  GtkWidget* self,
  gpointer user_data
)

Emitted when widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

Default handler:

The default handler is called before the handlers added via g_signal_connect().
