Dialog focus problem on java 7 and mac osx

21 views

Hi there,

I'm currently validating a swing application that runs on a browser (on an applets).
I came across with a problem for the java JRE 7 released by Oracle - this was not happening on Applet JRE 6 (1.6.0_33)

Every time I open a dialog within my application, that dialog comes to the front of the browser window but it does not request the focus as expected. THIS HAPPENS ONLY WHEN THE APPLET RUNS ON THE BROWSER.
Here is a small program to show the problem:

package com.macosx.tests;

import java.awt.Color;
import java.awt.Dimension;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JApplet;
import javax.swing.JButton;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;

public class AppletDialogExample extends JApplet{

private JPanel panel;
	private JButton openDialogBtn;
	
	private void doStart()
	{
		panel = new JPanel();
		panel.setPreferredSize(new Dimension(500,500));
		panel.setBackground(Color.GRAY);
		
		openDialogBtn = new JButton("open dialog");
		openDialogBtn.addActionListener(new ActionListener(){

@Override
			public void actionPerformed(ActionEvent arg0) {
				Runnable run = new Runnable()
				{
					public void run()
					{
						JPanel dialogPanel = new JPanel(new GridLayout(1,1));
						JTextField textField = new JTextField();
						dialogPanel.add(textField);
						
						JOptionPane.showConfirmDialog(null, dialogPanel);
					}
				};
				SwingUtilities.invokeLater(run);
			}
		});
		panel.add(openDialogBtn);
        setContentPane(panel);
	}
	
	@Override
	public void start() {
		try {
			SwingUtilities.invokeAndWait(new Runnable() {
				public void run() {
					doStart();
				}
			});
		} catch (Exception e) {
			throw new RuntimeException(e);
		}
	}
}</div>
