/**
* 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_toggle_button_set_mode()) 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.

Patch from Bill Haneman (with many modifications) to make the focus color Mon Dec 3 16:39:17 2001 Owen Taylor <otaylor@redhat.com> Patch from Bill Haneman (with many modifications) to make the focus color work on dark themes and to make the focus line width configurable. (#61079, #63074) * gtk/gtkwidget.c: Add style properties, ::focus-widget, ::focus-line-width, and ::focus-padding. * gtk/gtkstyle.[ch]: Make gtk_paint_focus() take a state argument as well so we can use fg[STATE] to draw instead of always drawing with black. Cange paint_focus() to respect GtkWidget::focus-width and GtkWidget::focus-line-pattern. Fix continuity problem where the default 1-1 stipple had a blob in one corner and a gap in the other. Change the interpretation of x/y/width/height to be the bounding box of the focus rect instead of the rectangle passed to gdk_draw_rectangle. * gtk/gtkcheckbutton.c gtk/gtklistitem.c gtk/gtknotebook.c gtk/gtkoptionmenu.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktextview.c gtk/gtktreeview.c: Handle ::focus-width and ::focus-line-padding. * gtk/gtkentry.c: Handle :;focus-width property; cleanup and remove duplicated code; fix drawing of focus rectangle when interior-focus = FALSE. (#63072, #63073) * gtk/gtkrange.c gtk/gtktext.c gtk/gtktreeitem.c gtk/gtktreeviewcolumn.c: Basic fixups to make compile; Range and TreeViewColumn will need more extensive fixing. * gtk/gtkcolorsel.c: Honor focus line attributes when drawing the focus on the color swatches. (#63071) * gtk/gtkhsv.c: Honor focus line attributes when drawing the focus for the ring and triangle. * docs/widget_geometry.txt: Start at documenting how various widgets are drawn. * gtk/gtkbutton.c (_gtk_button_paint): Export _gtk_button_paint() librarywide, so we don't have duplicate a bunch of code in gtktogglebutton.c. * gtk/gtktogglebutton.c: Use _gtk_button_paint().
