GtkWidget::map

This method maps a widget to the screen area it will take. It is mostly used internally, being one of the methods that is called as part of the show() routine. It causes the "map" signal to be emitted by the widget, which in turn switches a flag causing the widget to be mapped.

At the point of a widget's becoming mapped, the GdkEvent GDK_MAP is triggered, causing the "map-event" signal to also be emitted by that widget. Use this signal to trigger functions that rely on the map event having occurred.
