Get Mouse Position

If you're using Swing as your UI layer, you can use a Mouse-Motion Listener for this.

MouseInfo.getPointerInfo().getLocation() might be helpful. It returns a Point object corresponding to current mouse position.

Try looking at the java.awt.Robot class. It allows you to move the mouse programatically.

If you're using SWT, you might want to look at adding a MouseMoveListener as explained here.

PointerInfo a = MouseInfo.getPointerInfo();
Point b = a.getLocation();
int x = (int) b.getX();
int y = (int) b.getY();
System.out.print(y + "jjjjjjjjj");
System.out.print(x);
Robot r = new Robot();
r.mouseMove(x, y - 50);

In SWT you need not be in a listener to get at the mouse location. The Display object has the method getCursorLocation().

In vanilla SWT/JFace, call Display.getCurrent().getCursorLocation().

In an RCP application, call PlatformUI.getWorkbench().getDisplay().getCursorLocation().

For SWT applications, it is preferable to use getCursorLocation() over the MouseInfo.getPointerInfo() that others have mentioned, as the latter is implemented in the AWT toolkit that SWT was designed to replace.

In my scenario, I was supposed to open a dialog box in the mouse position based on a GUI operation done with the mouse. The following code worked for me:

    public Object open() {
//create the contents of the dialog
createContents();
//setting the shell location based on the curent position
//of the mouse
PointerInfo a = MouseInfo.getPointerInfo();
Point pt = a.getLocation();
shellEO.setLocation (pt.x, pt.y);


//once the contents are created and location is set-
//open the dialog
shellEO.open();
shellEO.layout();
Display display = getParent().getDisplay();
while (!shellEO.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
return result;
}

import java.awt.MouseInfo;
import java.awt.GridLayout;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.event.MouseListener;
import java.awt.event.MouseEvent;


import javax.swing.*;


public class MyClass {
public static void main(String[] args) throws InterruptedException{
while(true){
//Thread.sleep(100);
System.out.println("(" + MouseInfo.getPointerInfo().getLocation().x +
", " +
MouseInfo.getPointerInfo().getLocation().y + ")");
}
}
}

import java.awt.MouseInfo;
import java.util.concurrent.TimeUnit;


public class Cords {


public static void main(String[] args) throws InterruptedException {


//get cords of mouse code, outputs to console every 1/2 second
//make sure to import and include the "throws in the main method"


while(true == true)
{
TimeUnit.SECONDS.sleep(1/2);
double mouseX = MouseInfo.getPointerInfo().getLocation().getX();
double mouseY = MouseInfo.getPointerInfo().getLocation().getY();
System.out.println("X:" + mouseX);
System.out.println("Y:" + mouseY);
//make sure to import
}


}


}

I am doing something like this to get mouse coordinates using Robot, I use these coordinates further in few of the games I am developing:

public class ForMouseOnly {
public static void main(String[] args) throws InterruptedException {
int x = MouseInfo.getPointerInfo().getLocation().x;
int y = MouseInfo.getPointerInfo().getLocation().y;
while (true) {


if (x != MouseInfo.getPointerInfo().getLocation().x || y != MouseInfo.getPointerInfo().getLocation().y) {
System.out.println("(" + MouseInfo.getPointerInfo().getLocation().x + ", "
+ MouseInfo.getPointerInfo().getLocation().y + ")");
x = MouseInfo.getPointerInfo().getLocation().x;
y = MouseInfo.getPointerInfo().getLocation().y;
}
}
}
}
