Overview
Emitted when @widget is going to be mapped.
A widget is mapped when the widget is visible (which is controlled with
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 Gtk::Widget::#unmap
.
