/**
* SECTION:gtkcolorchooserwidget
* @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 predefined 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 color use gtk_color_chooser_get_rgba().
*
* The #GtkColorChooserWidget is used in the #GtkColorChooserDialog
* to provide a dialog for selecting colors.
*
* # CSS names
*
* GtkColorChooserWidget has a single CSS node with name colorchooser.
