NodePressAndDraggingEventListener (gephi 0.9.3 API)

All Superinterfaces:

ToolEventListener
```
public interface NodePressAndDraggingEventListener
extends ToolEventListener
```
Tool mouse press and dragging listener. Listen to a single node press on the visualization window and trigger selected nodes, then triggers continuously the recorded drag displacement.
The drag displacement is the difference between the start position and the current position in a 2D bottom-left coordinate system.
A tool which declares this listener is notified at a certain rate, up to multiple times per second, the selected nodes.
