/**
 * SECTION:gtkcolorseldlg
 * @Short_description: Deprecated dialog box for selecting a color
 * @Title: GtkColorSelectionDialog
 *
 * The #GtkColorSelectionDialog provides a standard dialog which
 * allows the user to select a color much like the #GtkFileChooserDialog
 * provides a standard dialog for file selection.
 *
 * Use gtk_color_selection_dialog_get_color_selection() to get the
 * #GtkColorSelection widget contained within the dialog. Use this widget
 * and its gtk_color_selection_get_current_color()
 * function to gain access to the selected color.  Connect a handler
 * for this widget’s #GtkColorSelection::color-changed signal to be notified
 * when the color changes.
 *
 * # GtkColorSelectionDialog as GtkBuildable # {#GtkColorSelectionDialog-BUILDER-UI}
 *
 * The GtkColorSelectionDialog implementation of the GtkBuildable interface
 * exposes the embedded #GtkColorSelection as internal child with the
 * name “color_selection”. It also exposes the buttons with the names
 * “ok_button”, “cancel_button” and “help_button”.
