JFrame not appearing on mouse click Location (SSCCE included)

I am trying to make a JFrame appear on mousePressed Location but I keep failing and it get's annoying :( Any ideas what isn't working?

import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class SSCCE
{

    @SuppressWarnings("static-access")
    public static void getInputData()
    {
        final JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(frame.DISPOSE_ON_CLOSE);
        JLabel emptyLabel = new JLabel("Test");
        frame.getContentPane().add(emptyLabel, BorderLayout.CENTER);
        frame.setSize(new Dimension(375, 100));

        MouseAdapter ml = new MouseAdapter()
        {

            @Override
            public void mousePressed(MouseEvent me)
            {

          开发者_JAVA百科      frame.setLocation(me.getX(), me.getY());
            }

            @Override
            public void mouseDragged(MouseEvent me)
            {
                frame.setLocation(me.getX(), me.getY());
            }
        };
        frame.getContentPane().addMouseListener(ml);
        frame.getContentPane().addMouseMotionListener(ml);

        frame.setVisible(true);

    }

    public static void main(String args[])
    {
        JFrame test = new JFrame();
        JButton but = new JButton("Click me");
        but.addActionListener(
                new ActionListener()
                {

                    public void actionPerformed(ActionEvent e)
                    {
                        getInputData();
                    }
                });
        test.getContentPane().add(but, BorderLayout.CENTER);
        test.setSize(500, 500);
        test.setVisible(true);


    }
}

Use the SwingUtilities methods convertPointToScreen() and convertPointFromScreen() to transform the MouseEvent coordinates.

Addendum: Alternatively, calculate the offset from getLocationOnScreen(), which is "the component's top-left corner in the screen's coordinate space."

Addendum: To position the new frame relative to the original mouse click, add a mouse listener to the parent frame instead of a button; use the coordinates to position the new frame, as shown below.

        frame.getContentPane().add(emptyLabel, BorderLayout.CENTER);
        frame.setPreferredSize(new Dimension(375, 100));

        MouseAdapter ma = new MouseAdapter() {

            Point local, global;
            Point delta = new Point();

            @Override
