If the label has been set so that it has a mnemonic key (using
i.e. [method@Gtk.Label.set_markup_with_mnemonic],
[method@Gtk.Label.set_text_with_mnemonic],
[ctor@Gtk.Label.new_with_mnemonic]
or the [property@Gtk.Label:use_underline] property) the label can be
associated with a widget that is the target of the mnemonic. When the
label is inside a widget (like a [class@Gtk.Button] or a
[class@Gtk.Notebook] tab) it is automatically associated with the correct
widget, but sometimes (i.e. when the target is a [class@Gtk.Entry] next to
the label) you need to set it explicitly using this function.
The target widget will be accelerated by emitting the
[signal@GtkWidget::mnemonic-activate] signal on it. The default handler for
this signal will activate the widget if there are no mnemonic collisions
and toggle focus between the colliding widgets otherwise.
Associate the label with its mnemonic target.
