40 * @Short_description: Deprecated dialog box for selecting a color
41 * @Title: GtkColorSelectionDialog
42 *
43 * The #GtkColorSelectionDialog provides a standard dialog which
44 * allows the user to select a color much like the #GtkFileChooserDialog
45 * provides a standard dialog for file selection.
46 *
47 * Use gtk_color_selection_dialog_get_color_selection() to get the
48 * #GtkColorSelection widget contained within the dialog. Use this widget
49 * and its gtk_color_selection_get_current_color()
50 * function to gain access to the selected color. Connect a handler
51 * for this widget’s #GtkColorSelection::color-changed signal to be notified
52 * when the color changes.
53 *
54 * # GtkColorSelectionDialog as GtkBuildable # {#GtkColorSelectionDialog-BUILDER-UI}
55 *
56 * The GtkColorSelectionDialog implementation of the GtkBuildable interface
57 * exposes the embedded #GtkColorSelection as internal child with the
58 * name “color_selection”. It also exposes the buttons with the names
59 * “ok_button”, “cancel_button” and “help_button”.
