Node events

Lienzo Nodes support event handling for Mouse Events, Touch Events and Drag Events (both with the mouse and touch interfaces.)

Each event has a corresponding Event Handler and a Node method to register the Event Handler:

Event Package Javadoc

Node Events	Node Event Handlers	Event related methods in the Node class

TODO Add here a note describing when we finish the functionality how to detect if we used LEFT, RIGHT or CENTER Click Button.

Drag related events

Only IPrimitive nodes (i.e. Groups and Shapes) can be dragged.

See Dragging for more information Mouse Event demo

Viewport events

Viewport Transform Changed events

To listen for changes in the Viewport Transform attribute, create a ViewportTransformChangedHandler and add it with Viewport.addViewportTransformChangedHandler().

See ViewportTransformChangedHandler.
