The SplitterWidth determines the width of the splitter bar in a tab group. All MdiTabGroup objects in the TabGroups collection have a splitter bar except the last one. The splitter bar is used by the end user to modify the Extent of a tab group.
When the user presses the logical left mouse button on the splitter bar, the SplitterDragging event is invoked to determine whether to allow the splitter bar to be repositioned. If the event is not cancelled, the user may move the splitter bar. Once the splitter bar is released, the Extent is updated (as well as that of the adjacent tab group) and the SplitterDragged event is invoked.
