Get Mouse Position

Question

I would like to simulate a natural mouse movement in Java (going from here to there pixel by pixel). To do that I need to know the starting coordinates.

I've found the method event.getX() and event.getY() but I need an event...

How can I know the positions without doing anything (or something not visible)?

Thank you

Answer 1

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

Answer 2

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.

Answer 3

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);

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

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;
}

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;
            }
        }
    }
}
