- java.awt.event.MouseAdapter
- - gov.nih.mipav.model.algorithms.ContourPlot.CoordSysPanning

All Implemented Interfaces:

ContourPlot.InteractionConstants, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.event.MouseWheelListener, java.util.EventListener

Enclosing class:

ContourPlot
```
public class ContourPlot.CoordSysPanning
extends java.awt.event.MouseAdapter
implements ContourPlot.InteractionConstants
```
The CoordSysPanning class implements a MouseListener and MouseMotionListener that realize panning functionality for the coordinate view of the ContourPlot.CoordSysRenderer. When registering this with an ContourPlot.JPlotterCanvas and CoordSysRenderer dragging with the left mouse button over the Canvas while holding down CTRL will set the coordinate view accordingly.
Intended use: CoordSysPanning pan = new CoordSysPanning(canvas, coordsys).register();
Per default the extended modifier mask for a dragging mouse event to trigger panning is InputEvent.CTRL_DOWN_MASK. If this is undesired the extModifierMask has to be overridden.
For example to not need to press any key:
```
new CoordSysPanning(canvas){{extModifierMask=0;}}.register();
```
