/**
* SECTION:gtkcheckbutton
* @Short_description: Create widgets with a discrete toggle button
* @Title: GtkCheckButton
* @See_also: #GtkCheckMenuItem, #GtkButton, #GtkToggleButton, #GtkRadioButton
*
* 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.
*
* # CSS nodes
*
* |[<!-- language="plain" -->
* checkbutton
* check
* <child>
* ]|
*
* A GtkCheckButton with indicator (see gtk_check_button_set_draw_indicator()) has a
* main CSS node with name checkbutton and a subnode with name check.
*
* |[<!-- language="plain" -->
* button.check
* check
* <child>
* ]|
*
* 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.
