+ * @Short_description: A widget for choosing colors
+ * @Title: GtkColorChooserWidget
+ * @See_also: #GtkColorChooserDialog
+ *
+ * The #GtkColorChooserWidget widget lets the user select a
+ * color. By default, the chooser presents a prefined palette
+ * of colors, plus a small number of settable custom colors.
+ * It is also possible to select a different color with the
+ * single-color editor. To enter the single-color editing mode,
+ * use the context menu of any color of the palette, or use the
+ * '+' button to add a new custom color.
+ *
+ * The chooser automatically remembers the last selection, as well
+ * as custom colors.
+ *
+ * To change the initially selected color, use gtk_color_chooser_set_rgba().
+ * To get the selected font use gtk_color_chooser_get_rgba().
+ *
+ * The #GtkColorChooserWidget is used in the #GtkColorChooserDialog
+ * to provide a dialog for selecting colors.
+ *
+ * Since: 3.4
