[ 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 [[email protected]: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 [[email protected]:GtkWidget:unmap
].
