How Can I Ensure My Java JFileChooser Always Appears in Front?

Bringing JFileChooser to the Forefront of All Windows

While using Java's JFileChooser to select files, you may encounter a scenario where the file chooser appears behind other windows, requiring you to minimize them to access it. This can be a frustrating hindrance, especially during testing.

The reason for this behavior lies in the API for showOpenDialog(), which refers to a "look-and-feel-dependent position," causing the dialog to be placed in the center of the screen when the parent parameter is null. To remedy this, we can explicitly control the positioning of the file chooser.

Here's an example that demonstrates this approach:

import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.Graphics;
import java.awt.Toolkit;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;

public class FileChooserOnTop extends JPanel {

    private JFileChooser chooser = new JFileChooser();

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

    public void create() {
        JFrame f = new JFrame();
