47 * SECTION:ctkstyle
48 * @Short_description: Object that holds style information
49 * for widgets
50 * @Title: CtkStyle
51 *
52 * A #CtkStyle object encapsulates the information that provides the look and
53 * feel for a widget.
54 *
55 * Each #CtkWidget has an associated #CtkStyle object that is used when
56 * rendering that widget. Also, a #CtkStyle holds information for the five
57 * possible widget states though not every widget supports all five
58 * states; see #CtkStateType.
59 *
60 * Usually the #CtkStyle for a widget is the same as the default style that
61 * is set by CTK+ and modified the theme engine.
62 *
63 * Usually applications should not need to use or modify the #CtkStyle of
64 * their widgets.
