C# 클래스 UMD.HCIL.Piccolo.Event.PDragSequenceEventHandler

PDragSequenceEventHandler is designed to support mouse pressed, dragged, and released interaction sequences. Support is also provided for running a continuous activity during the drag sequence.

PDragSequenceEventHandler should be subclassed by a concrete event handler that implements a particular interaction. See PPanEventHandler, PZoomEventHandler, and PDragEventHandler for examples

메소드	설명
OnDrag ( object sender, PInputEventArgs e ) : void	Subclasses should override this method to get notified of the drag events in a drag sequence. This method is called in the middle of a drag sequence, between the OnStartDrag and the OnEndDrag methods. Unlike the OnMouseDrag method, this method will not get called until after the MinDragStartDistance has been reached. Notes to Inheritors: Overriding methods must still call `base.OnDrag()` for correct behavior.
OnDragActivityFinalStep ( object sender, PInputEventArgs e ) : void	Override this method to get notified when the drag activity stops stepping.
OnDragActivityFirstStep ( object sender, PInputEventArgs e ) : void	Override this method to get notified when the drag activity is stepping. During a drag sequence an activity is scheduled that runs continuously while the drag sequence is active. This can be used to support some additional behavior that is not driven directly by mouse events. For example PZoomEventHandler uses it for zooming and PPanEventHandler uses it for auto panning.
OnDragActivityStep ( object sender, PInputEventArgs e ) : void	Override this method to get notified when the drag activity starts stepping.
OnEndDrag ( object sender, PInputEventArgs e ) : void	Subclasses should override this method to get notified of the end event in a drag sequence. This method is called at the end of a drag sequence. Unlike the OnMouseDrag method, this method will not get called until after the MinDragStartDistance has been reached. Notes to Inheritors: Overriding methods must still call `base.OnEndDrag()` for correct behavior.
OnStartDrag ( object sender, PInputEventArgs e ) : void	Subclasses should override this method to get notified of the start of a new drag sequence. This method is called at the beginning of a drag sequence. Unlike the OnMouseDrag method, this method will not get called until after the MinDragStartDistance has been reached. Notes to Inheritors: Overriding methods must still call `base.OnStartDrag()` for correct behavior.
ShouldStartDragInteraction ( PInputEventArgs e ) : bool	Returns true if a drag sequence should be initiated.
StartDragActivity ( PInputEventArgs e ) : void	Schedules the drag activity to run.
