  43  * @Short_description: Deprecated dialog box for selecting a color
  44  * @Title: GtkColorSelectionDialog
  45  *
  46  * The #GtkColorSelectionDialog provides a standard dialog which
  47  * allows the user to select a color much like the #GtkFileSelection
  48  * provides a standard dialog for file selection.
  49  *
  50  * Use gtk_color_selection_dialog_get_color_selection() to get the
  51  * #GtkColorSelection widget contained within the dialog. Use this widget
  52  * and its gtk_color_selection_get_current_color()
  53  * function to gain access to the selected color.  Connect a handler
  54  * for this widget's #GtkColorSelection::color-changed signal to be notified
  55  * when the color changes.
  56  *
  57  * <refsect2 id="GtkColorSelectionDialog-BUILDER-UI">
  58  * <title>GtkColorSelectionDialog as GtkBuildable</title>
  59  * The GtkColorSelectionDialog implementation of the GtkBuildable interface
  60  * exposes the embedded #GtkColorSelection as internal child with the
  61  * name "color_selection". It also exposes the buttons with the names
  62  * "ok_button", "cancel_button" and "help_button".
