"Child class" is an invented term anyway, and it conceptually defines identifiable regions in widgets.

|
|
* @Short_description: An object that hold style information for widgets
|
|
* @Title: GtkStyle
|
|
*
|
|
* A #GtkStyle object encapsulates the information that provides the look and
|
|
* feel for a widget. Each #GtkWidget has an associated #GTkStyle object that
|
|
* is used when rendering that widget. Also, a #GtkStyle holds information for
|
|
* the five possible widget states though not every widget supports all five
|
|
* states; see #GtkStateType.
|
|
*
|
|
* Usually the #GtkStyle for a widget is the same as the default style that is
|
|
* set by GTK+ and modified the theme engine.
|
|
*
|
|
* Usually applications should not need to use or modify the #GtkStyle of their
|
|
* widgets.
