* @Short_description: A standard 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 #GtkFileSelection
* 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.
*
* <refsect2 id="GtkColorSelectionDialog-BUILDER-UI">
* <title>GtkColorSelectionDialog as GtkBuildable</title>
* 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".
* </refsect2>
