JDialog Focus issues in JRE 1.6

Thanks for the prompt reply. Unfortunately that didn't work, tho I cannot see why as the code is definitely being called.

I've stripped all the date stuff out the panel to leave just 2 buttons in the dialog. Here is the class...

package test;

import java.awt.Component;

import java.awt.Dialog;

import java.awt.Frame;

import java.awt.SystemColor;

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import java.awt.event.FocusEvent;

import java.awt.event.FocusListener;

import java.awt.event.KeyEvent;

import java.awt.event.KeyListener;

import java.awt.event.MouseEvent;

import java.awt.event.MouseListener;

import java.util.Date;

import javax.swing.BorderFactory;

import javax.swing.JButton;

import javax.swing.JDialog;

import javax.swing.JPanel;

import javax.swing.SwingUtilities;

public class DateChooser extends JDialog

implements MouseListener, FocusListener,

KeyListener, ActionListener

{

private static final long serialVersionUID = -6725186298620856660;

private JButton ok;// "Ok" button.

private JButton cancel;// "Cancel" button.

public boolean focusLost = false; // focus change caused close

public boolean okClicked = false;

private void construct()

{

// Turn off window border

setUndecorated(true);

addFocusListener(this);

// Create content pane

JPanel content = new JPanel();

content.setBorder(BorderFactory.createLineBorder(WindowsBorderColour.m_borderCol,1));

content.addFocusListener(this);

// Create the OK button

//

ok = new JButton("OK");

ok.addActionListener(this);

ok.setFocusable(true);

ok.addKeyListener(this);

ok.addFocusListener(this);

ok.setOpaque(false);

// Create the cancel button

//

cancel = new JButton("Cancel");

cancel.addActionListener(this);

cancel.setFocusable(true);

cancel.addKeyListener(this);

cancel.addFocusListener(this);

cancel.setOpaque(false);

// Create a buttons panel

//

JPanel buttons = new JPanel();

buttons.add(ok);

buttons.add(cancel);

buttons.setBackground(SystemColor.inactiveCaption);

buttons.addFocusListener(this);

// Add all the controls to the content panel

//

content.setLayout(getContentPane().getLayout());

content.add("South", buttons);

content.doLayout();

// Update the dialog

//

setContentPane(content);

pack();

setResizable(false);

buttons.requestFocus();

}

/**

* Called when the "Ok" button is pressed. Just sets a flag and hides the

* dialog box.

*/

public void actionPerformed(ActionEvent e)

{

if (e.getSource() == ok) okClicked = true;

setVisible(false);

}

public void focusGained(FocusEvent e)

{

System.out.println("****** Date got focus " + e.getSource());

}

public void focusLost(FocusEvent e)

{

System.out.println("****** Date lost focus" + e.getSource());

}

public void keyPressed(KeyEvent e)

{

System.out.println("Key pressed " + e);

// Deal with panel specific keys

//

switch (e.getKeyCode())

{

case KeyEvent.VK_ESCAPE:

setVisible(false);

break;

case KeyEvent.VK_TAB:

Component comp = getFocusOwner();

if (e.isShiftDown())

comp.transferFocusBackward();

else

comp.transferFocus();

break;

case KeyEvent.VK_ENTER:

if (e.getSource() != cancel) okClicked = true;

setVisible(false);

break;

}

}

public void mouseClicked(MouseEvent e)

{

System.out.println("Mouse clicked" + e);

}

public void keyReleased(KeyEvent e)

{

}

public void keyTyped(KeyEvent e)

{

}

public void mouseEntered(MouseEvent e)

{

}

public void mouseExited(MouseEvent e)

{

}

public void mousePressed(MouseEvent e)

{

}

public void mouseReleased(MouseEvent e)

{

}

public DateChooser(Dialog owner, String title)

{

super(owner, title, true);

construct();

}

public DateChooser(Dialog owner)

{

super(owner, true);

construct();

}

public DateChooser(Frame owner, String title)

{

super(owner, title, true);

construct();

}

public DateChooser(Frame owner)

{

super(owner, true);

construct();

}

public Date select(Date date)

{

System.out.println("Select >>>");

this.addWindowListener(new java.awt.event.WindowAdapter()

{

public void windowOpened(java.awt.event.WindowEvent e)

{

System.out.println("Window opened");

SwingUtilities.invokeLater(new Runnable()

{

public void run()

{

System.out.println("requestFocusInWindow");

ok.requestFocusInWindow();

}

});

}

});

okClicked = false;

System.out.println("Before set visible");

setVisible(true);

System.out.println("After set visible");

if (!okClicked) return null;

System.out.println("Select <<<");

return new Date();

}

public Date select()

{

return select(new Date());

}

}

Which is called from the applet using...

Frame frame = new Frame();

DateChooser dc = new DateChooser(frame);

dc.setSize(200,200);

Date newDate = dc.select();

The trace I get out is...

Select >>>

Before set visible

Window opened

requestFocusInWindow

If I press a key nothing happens but as soon as I press the mouse down on a button I get the trace...

****** Date got focus javax.swing.JButton[,49,5,47x23, ...

and then when I press a key, I get the events as expected...

Key pressed java.awt.event.KeyEvent[KEY_PRESSED,keyCode=27,keyText=Escape,...

The mouse down must do something to set the focus so I think I may try and decompile that to see what it does. If you have any further thoughts I'd appreciate them!

I get the same result as before with that code moved into the construct method. As it will only be fired on window open I guess it doesn't matter where it is added as long as it is done so before the setVisible(true).

Either way, the method is clearly being called but the requestFocusInWindow() is being ignored by the runtime. I believe that there are conditions when that is true as it is a "request" rather than a "demand" (shame!).

One important point I forgot is that this is Internet Explorer 7 too, which could be an issue.
