All Implemented Interfaces:

ILcdAWTEventListener, ILspController

public class TLspZoomToController
extends ALspController

Performs a "zoom to" animation when the user double-clicks in the view. The animation pans the view so that it is centered on the click location, and simultaneously zooms in on the same point.
A double-click using the left mouse button will trigger a "zoom in" animation while a double click using the right mouse button will trigger a "zoom out" animation.

The zoom-to controller only accepts double click events as a trigger for starting the animation. Events that make a double click impossible like a mouse dragged event, will cause this controller to automatically delegate the received pressed event, all consecutive drag events and the released event. You can add a MouseButton filter to further limit the events this controller will use (only left mouse button for instance). The fact that it only accepts double click events also means that any other events, such as single clicks, are delegated.
