A #GtkCheckButton places a discrete #GtkToggleButton next to a widget,
(usually a #GtkLabel). See the section on #GtkToggleButton widgets for
more information about toggle/check buttons.
The important signal ( #GtkToggleButton::toggled ) is also inherited from
#GtkToggleButton.
A GtkCheckButton without indicator changes the name of its main node
to button and adds a .check style class to it. The subnode is invisible
in this case.
