46 * Implementation of widget for shapes selection. This widget provides selection of several shapes.
47 * It can be defined in XML file as following:
49 * <multi_selector id="group_list"
50 * tooltip="Select a set of objects"
51 * type_choice="Vertices Edges Faces Solids" />
53 * It uses following parameters:
54 * - id - is a name of corresponded attribute
55 * - tooltip - a tooltip for the widget
56 * - type_choice - list of expected shape types.
