54 * Implementation of widget for shapes selection. This widget provides selection of several shapes.
55 * It can be defined in XML file as following:
57 * <multi_selector id="group_list"
58 * tooltip="Select a set of objects"
59 * type_choice="Vertices Edges Faces Solids" />
61 * It uses following parameters:
62 * - id - is a name of corresponded attribute
63 * - tooltip - a tooltip for the widget
64 * - type_choice - list of expected shape types.
