map (
  GtkWidget* self,
  gpointer user_data

Description [src]

The ::map signal is emitted when widget is going to be mapped, that is when the widget is visible (which is controlled with gtk_widget_set_visible()) and all its parents up to the toplevel widget are also visible. Once the map has occurred, GtkWidget::map-event will be emitted.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of GtkWidget::unmap.

Default handler:

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