示例1: StartDraggingTab

{
	Tabs.Remove(TabToStartDragging);
	// We just removed the foreground tab.
	ForegroundTabIndex = INDEX_NONE;
	ParentTabStackPtr.Pin()->OnTabRemoved(TabToStartDragging->GetLayoutIdentifier());

	// Tha tab well keeps track of which tab we are dragging; we treat is specially during rendering and layout.
	TabBeingDraggedPtr = TabToStartDragging;
		
	TabGrabOffsetFraction = InTabGrabOffsetFraction;

	// We are about to start dragging a tab, so make sure its offset is correct
	this->ChildBeingDraggedOffset = ComputeDraggedTabOffset( MouseEvent.FindGeometry(SharedThis(this)), MouseEvent, InTabGrabOffsetFraction );

	// Start dragging.
