[ HasEmitter ]
public virtual signal void map ()

Emitted when widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with [property@Gtk.Widget:visible]) and all its parents up to the toplevel widget are also visible.

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 [signal@Gtk.Widget:GtkWidget:unmap].
