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