| Unselect | Overloaded. Unselects the given node, if it is currently selected, and posts a SELECTION_CHANGED_NOTIFICATION if the current selection has changed. |
| UnselectAll | Unselects all the nodes that are currently selected, and posts a SELECTION_CHANGED_NOTIFICATION if the current selection has changed. |
Protected Instance Methods
 ComputeMarqueeSelection | Select the selectable nodes whose bounds intersect the marquee, unselecting previously selected nodes. |
| ComputeOptionMarqueeSelection | Select the selectable nodes whose bounds intersect the marquee, without unselecting previously selected nodes. |
| CreateNodeFilter | Creates a new PSelectionEventHandler.BoundsFilter with the given bounds. |
| DragStandardSelection | Drags the nodes in a standard selection. |
| EndMarqueeSelection | Ends a marquee selection sequence. |
| EndStandardSelection | Ends a standard selection sequence. |
| Finalize (inherited from Object) | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. |
| Init | Called by the constructors to perform some common initialization tasks. |
| InitializeMarquee | Sets some initial values for the marquee including it's brush and pen. |
| InitializeSelection | Sets the initial press point and press node for the selection. |
| InternalSelect | Selects the given node, if it is not already selected. |
| InternalUnselect | Unselects the given node, if it is currently selected. |
| IsSelectable | Determines if the specified node is selectable (i.e., if it is a child of a node in the list of selectable parents). |
| MemberwiseClone (inherited from Object) | Creates a shallow copy of the current Object. |
| OnDrag | Overridden. See PDragSequenceEventHandler.OnDrag. |
| OnDragActivityFinalStep (inherited from PDragSequenceEventHandler) | Override this method to get notified when the drag activity stops stepping. |
| OnDragActivityFirstStep (inherited from PDragSequenceEventHandler) | Override this method to get notified when the drag activity is stepping. |
| OnDragActivityStep | Overridden. This gets called continuously during the drag, and is used to animate the marquee. |
| OnEndDrag | Overridden. See PDragSequenceEventHandler.OnEndDrag. |
| OnStartDrag | Overridden. See PDragSequenceEventHandler.OnStartDrag. |
| PBasicInputEventHandlerAcceptsEvent (inherited from PBasicInputEventHandler) | The filter for a PBasicInputEventHandler. This method only rejects an event if it has already been marked as handled. |
| Select | Overloaded. Selects each node used as a key in the dictionary, if the node is not already selected. |
| SetSafeMarqueePen | When the width and the height are too small to render the path using the current pen, this method sets the marquee to a pen that can render the path safely. |
| ShouldStartDragInteraction (inherited from PDragSequenceEventHandler) | Returns true if a drag sequence should be initiated. |
| StartDragActivity (inherited from PDragSequenceEventHandler) | Schedules the drag activity to run. |
| StartMarqueeSelection | Starts a marquee selection sequence. |
| StartOptionMarqueeSelection | Starts an option marquee selection sequence (i.e. a marquee selection sequence where the Shift key was pressed). |
