MathMouseMotionListener (J/Link 5.3 API Documentation)

java.lang.Object
- com.wolfram.jlink.MathListener
- - com.wolfram.jlink.MathMouseMotionListener

All Implemented Interfaces:

java.awt.event.MouseMotionListener, java.util.EventListener
```
public class MathMouseMotionListener
extends MathListener
implements java.awt.event.MouseMotionListener
```
This class lets you trigger a call into Mathematica on the occurrence of a particular event. Like all the MathXXXListener classes, it is intended to be used primarily from Mathematica, although it can be used from Java code as well.
In response to a MouseEvent, objects of this class send to Mathematica:
```
     userCode[theMouseEvent, theMouseEvent.getX(), theMouseEvent.getY(), theMouseEvent.getClickCount()]
```
userFunc is specified as a string, either a function name or an expression (like a pure function "foo[##]&"), via the setHandler() method.

Constructor Summary

Constructors
Constructor	Description
`MathMouseMotionListener()`	The constructor that is called from Mathematica.
`MathMouseMotionListener(KernelLink ml)`	You must use this constructor when using this class in a Java program, because you need to specify the KernelLink that will be used.
`MathMouseMotionListener(java.lang.String[][] handlers)`	This form of the constructor lets you skip having to make a series of setHandler() calls.

```
public MathMouseMotionListener()
```
    The constructor that is called from Mathematica.
  - MathMouseMotionListener
```
public MathMouseMotionListener(KernelLink ml)
```
    You must use this constructor when using this class in a Java program, because you need to specify the KernelLink that will be used.
    
    Parameters:
    
    ml - The link to which computations will be sent when MouseEvents arrive.
  - MathMouseMotionListener
```
public MathMouseMotionListener(java.lang.String[][] handlers)
```
    This form of the constructor lets you skip having to make a series of setHandler() calls. Use this constructor from Mathematica code only.
    
    Parameters:
    
    handlers - An array of {meth, func} pairs associating methods in the MouseMotionListener interface with Mathematica functions.
