How to get the current X and Y position of a window?

Mark Sizzler · May 15, 2009

I can get the current height and width of a window by commands like:

this.getWidth()
and
this.getHeight()

But how do I get current X and Y position of this window?

If you said about java.awt.Window, then you can use:
Window.getGraphicsConfiguration().getBounds();

Well, if by window you mean Window, see..
Component.getLocationOnScreen().

Try SwingUtilities#convertPointToScreen():

package news;

import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.GridLayout;
import java.awt.Point;
import java.awt.event.ComponentAdapter;
import java.awt.event.ComponentEvent;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

/** @author John B. Matthews */
public class GridTest {

private static final int ROWS = 5;
private static final int COLS = 4;

public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
//@ Override
public void run() {
new GridTest().create();
}
});
}

void create() {
JPanel panel = new JPanel();
panel.setLayout(new GridLayout(ROWS, COLS));
for (int i = 0; i < ROWS * COLS; i++) {
panel.add(new LabelPanel());
}
JFrame f = new JFrame("GridTest");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.add(panel);
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
}
}

/**
* A LabelPanel has a label showing its current size & location.
*/
class LabelPanel extends JPanel {

private static final String FORE =
"<html><body align=center>";
private static final String AFT =
" ubi in mundum</body></html>";
private final JLabel sizeLabel = new JLabel();
private final Point p = new Point();

public LabelPanel() {
this.setPreferredSize(new Dimension(150, 75));
this.add(sizeLabel);
this.addComponentListener(new ComponentAdapter() {
@Override
public void componentResized(ComponentEvent e) {
int w = e.getComponent().getWidth();
int h = e.getComponent().getHeight();
p.setLocation(0, 0);
SwingUtilities.convertPointToScreen(p, sizeLabel);
sizeLabel.setText(FORE

+ "Loc: " + p.x + "," + p.y
+ AFT);
}
});
}
}

If your window descends from java.awt.Component
you could:

int x = this.getLocation().x;
int y = this.getLocation().y;

See Component.getBounds().

Look up getLocation()

It would be helpful if you would be more specific about what you mean by
"window". If you mean java.awt.Component or any of its subclasses (e.g.
java.awt.Window, java.awt.Frame, javax.swing.JFrame, javax.swing.JWindow)
then the answer is

public Point getLocationOnScreen()

See the javadocs for Component for details.

Side note:
this.getWidth() and this.getHeight() can usually (always?) be simplified to
getWidth() and getheight().

See

and
