mouse
In Java you deal with the mouse by fielding events. You get a MouseMotion event at your MouseMotionListener each time the mouse moves or a MouseEvent at your MouseListener each time user clicks a button.

You don’t see mouse events that happen outside your component. Further, you won’t mouse events on Components like JButton that process MouseEvents and turn them into ActionEvents.

If you want to know what the mouse is doing outside your component, or even outside your application you need to use Java version 1.5 and use the MouseInfo class. To do this in earlier versions, you need to use C++ and JNI (Java Native Interface), using the Windows

GetCursorPos ( tagPOINT );
I have created a JNI Mouse class that does this for versions prior to JDK (Java Development Kit) 1.5.
