JTextField in a FullScreen JWindow jdk1.4

I have a problem that must have a simple solution I hope.
I have a JWindow wich I run in fullscreen mode, the contentPane of the JWindow contains a JPanel wich contains JButtons, JLabels and JTextFields I have no problem with the JButtons and JLabels, but the JTextFields get no cursor when clicked and it is therefore impossible to enter text into them.
I tried using the same JPanel in an ordinary JFrame (not fullscreen) and it worked just as it should.
What am I missing?
The JPanel (shortened)
import java.awt.*;
import java.awt.image.*;
import java.awt.event.*;
import javax.swing.*;
class TheMainMenuPanel extends JPanel
     private BufferedImage background;
     private Graphics2D g2;
     private JButton exitButton=new JButton("Exit Game");
     private JTextField portField=new JTextField(5);
     private JLabel portLabel=new JLabel("Port of game");
     public TheMainMenuPanel()
          Image tmp=new ImageIcon("Graphics\\MainMenuBack.gif").getImage();
          background=ImageUtilities.makeBufferedImage(tmp);
          exitButton.addActionListener(new ActionListener()
               public void actionPerformed(ActionEvent e)
                    System.exit(0);
add(portLabel);
     add(portField);
add(exitButton);
     public void paintComponent(Graphics g)
          g2=(Graphics2D)g;
          g2.drawImage(background,0,0,null);
I'd be happy for any answer

I got the same problem with a JTextArea and a JWindow in fullscreen mode.
How did you got in fullscreen with a JFrame?
did you found an other solution?
thanks for your help

Child JWindow containing JTextField takes focus from JFrame

I have a bit of a unique problem.
I have a JFrame as the main application window. I then create a JWindow with a JTextField that I would like to use as a Popup Palette. The problem is that when I click in the text box, the title bar of the JFrame changes it's appearance because the focus is now on the text box in the JWindow.
If I use setFocusableWindowState(false) on the JWindow then the title bar of the JFrame does not change(which is the behaviour I want), but I cannot type in the JTextField.
I understand why this is happening. The JTextField needs to have focus in order to recieve input and because it is in the JWindow, the JWindow takes the focus away from the JFrame.
Does anyone know how I can make it so the JFrame Title Bar does not change appearance when the JTextField in the JWindow gets focus?
The only thing that I can think of, is to somehow change the JFrame Look & Feel so that the title does not change appearance when the JFrame looses focus. I have no idea how to do that though.
If you are wondering why I need this, it is because I need a JTextField to display on top of a Heavyweight component. I want it to appear as if it is part of the same window. Having the title bar of the JFrame change when you click in the textbox kind of destroys the illusion that it is part of the heavyweight component.
Also, if you know of any other ways to get the JTextField to display and work on top of a Heavyweight component then I would appreciate that as well.
Here is an example that you can run to see the behaviour. You can try it with the setFocusableWindowState line both uncommented and commented out.

import java.awt.Dimension;

public class TestFocus implements Runnable {
    private JFrame frame;
    private JWindow popup;
    public void run() {
        //Create a new Frame
         frame = new JFrame("Frame Test");
         JButton but = new JButton("Does Nothing");
        frame.getContentPane().add(but);
        frame.setPreferredSize(new Dimension( 500, 500 ));
        frame.pack();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
        //Create a JWindow with a JTextField
        popup = new JWindow( frame );
        JPanel p = new JPanel(new BorderLayout());
        JTextField txt = new JTextField();
        p.add( txt, BorderLayout.NORTH );
        JButton but2 = new JButton("Also does nothing");
        p.add(but2, BorderLayout.SOUTH);
        popup.getContentPane().add(p);
        popup.setLocation( frame.getLocation().x + 50, frame.getLocation().y + 50 );
        popup.pack();
        //Proper title behaviour if I have this statement
        //but then I can't type in the text box.
        //popup.setFocusableWindowState(false);
        popup.setVisible(true);
    public static void main(String[] args) {
        try {
            System.setProperty("sun.java2d.noddraw", "true");
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        catch (Exception e) {
        SwingUtilities.invokeLater(new TestFocus());
}Thanks,
Jeff

The code works fine on XP using JDK1.4.2, maybe its a version/platform issue check the bug database.
-> if you know of any other ways to get the JTextField to display and work on top of a Heavyweight component
You could try using
JPopupMenu.setDefaultLightWeightPopupEnabled(false)and then add the JTextField to a jPopupMenu instead of a JWindow (although behind the scenes I think it will use a JWindow as the popup, so it may not solve the problem either if it is a version/platform issue).

Removing Border from a JtextField

Hi all
how do i remove the border surrounding the JTExtfield in my applet (using jdk1.3)
Thank You

A brief browsing of the Java documentation (which I always keep close at hand) indicates that JComponent has the setBorder() method. A website mentioned in the setBorder part gives this example (I haven't tested it):
nameOfTextField.setBorder(BorderFactory.createEmptyBorder());Here is the site I extracted it from:
http://java.sun.com/docs/books/tutorial/uiswing/misc/border.html

Setting size.... goes terrible wrong

Dear mr. java,
I have some troubles of setting the size of my JPanels... I thought I just could with setsize(), but that doesn't work... If I run my code now, I have a very wide window. with very big buttons.
Also In my left panel I added GridBagLayout (I thought that would solve the problem) but It doesn't stay fixed, the buttons doesnt do wath Im telling them.
In short it doesnt do anything I tell him about placement and sizing :-s!
Some poeple have any idea?

}

can u explain what u want???
I observed something like u add twice this line analyse.add(progress) u delete the second time add(progress).
Set the size to the JFrame,
and use GridBagLayout, instead of GridLayout,
GridLayout will divide the space equally, that's why u'r getting Analyse
and Parameter Buttons in the Bigger and equal in size.

Managing Popup Visibility

Hi all, my question is this:
How can I make a popup that behaves like a JPopupMenu or JComboMenu, specifically it's criteria for Hiding.
To clarify, When the popup is visible if the moused is pressed anywhere on the screen other than over the popup it should hide.
I've spent 2 weeks on this one thing and I am no closer to an answer, it seems there's not really any resources on this available.

excuse me,JWindow does't handle DeActiveEvent ;
There's my code , I'll make it like jdesktop's auto complet component or code assistant but ...

My question is I dosen't know the theory , how swing manage popup item hiden;
I want a JTextField ,when I input word,it can drop down a popup assistant help me auto complete.
First I use PopupFactory to implement the function,but finally I notice that I can't hide the popup in an evnent.
Then I think maybe use somethin like menu can implement the function.So I use JPopupMenu ,but when it popup,the JTextField's focuse lose,I can't input still.then when JPopupMenu shown I set jTextField to requestFocuse().That's all .My problem resolved.But I still dose't know how the JPopupMenu hiden ,when click any where but the menu.And I tried use JWindow ,but it dosen't catch the deActive window event.
I hope can understand how swing manager popup show or hiden,maybe intro some article or indicate some code block can help me .I like java for he tell me what he do when a program running,

This component still a lot to be desired in terms of functionality. One immediately missing feature is the ability scroll up and down the List with the keyboard.
I seen most of the functionality previously implemented, (I believe keybinds were added to the document in order for it to be able to forward the scroll commands to the List).
I'm sure you can work it out. All the best

When location of component changed on screen?

Hi,
I have Code that brings up a message in a JDialog under a JTextComponent. I calculate the bottom - left point of the TextComponent and set my Dialog to show up there. However I have a problem keeping it there when the window moves, the TextComponent moves or One of it's parents moves.
I need something that will tell me when the location on screen of the TextComponent changes.
Thanks,
Shaul

How to gain focus to a JTextField in a Jwindow

Hi Friends
I am trying to create a Login screen which covers the entire desktop using a Jwindow.
I have one JTextfield and JPassword field in the Jwindow but i am not able to gain focus to those text fields and not able to type anything in those fields...
I am using java 1.4.2
This is my program...
public class Login implements ActionListener
        JWindow fs;
        JTextField tx1;
        JPasswordField tx2;
         public Login ()
             fs= new JWindow(new JFrame());
             tx1= new JTextField(12);
             tx2= new JPasswordField(12);
             JButton jb = new JButton();
             fs.getContentPane().setLayout(new FlowLayout());
             fs.getContentPane().add(tx1);
             fs.getContentPane().add(tx2);
             fs.getContentPane().add(jb);
             fs.setSize(300,300);
             fs.setVisible(true);
             fs.show();
             fs.toFront();
public void actionPerformed (ActionEvent e)
     System.out.println("User id "+tx1.getText()+" and Password is : "+tx2.getText()):
public static void main(String[] args)
    new Login();
     Can some one help me in solving this issue with JWINDOW... Plz dont suggest JFrame , since i am not willing to use that header....

Two very STRANGE problems with JWindow and JTextField

I am having some trouble in the program that I am making. It is a Swing based GUI.
I have a JWindow with a JPanel in it that holds JTextFields and JLabels.
problem1----I can't see a caret in any of the textfields but I can still enter text.
problem2----If I control + tab to another window, and control + tab to get back to the JWindow then I can see a caret, but the caret will not change if I click on another textfield and also I can't move to another textfield to enter text. If i do another control tab, then the textfield that i tried to switch to will have focus, but there is now two carets...the first one is where I was but that field does not have focus. I can do this control-tab for as many textfields as I need to fill, but it obviously is not practical.
I am using a call to super(Frame frame) when calling my JWindow but that didn't seem to fix it.
Any help would be great!!!!! thanks john

try checking out this thread :
http://forum.java.sun.com/thread.jsp?forum=57&thread=153344
sounds like your problem, kinda. it looks more like a repaint issue, since u get two carets at the same time - as if the screen isn't refreshing enough (u could give it some Spearmint POLO :)

Jwindow behaves differently in jdk1.5

Hi,
I created a splash screen using jwindow. In the earlier versions of jdk the splash screen (Jwindow component) can be moved back and i was able to switch to other applications. But when i used jdk 1.5 the Jwindow stays on top and even if i switch to other applications it remains on top. how can i resolve this ??? Is there any change in the behavior of the JWindow in jdk 1.5. This is urgent can any one help???
Regards,
Jonny

if having the app show up in the task bar is not a problem, you could use a
JFrame, then setUndecorated(true); so it will look like a JWindow.
Otherwise, this is just a stab in the dark, but worth a try
(uses a JFrame parent, but doesn't show in the task bar)
import javax.swing.*;
class Testing
public static void main(String[] args)
    JWindow window = new JWindow(new JFrame(){
      public boolean isShowing(){return true;}});
    window.getContentPane().add(new javax.swing.JLabel("Hello World"));
    window.setLocation(400,300);
    window.setSize(200,200);
    window.setVisible(true);
}

JTextField not responding when app jar'd

I have a few JTextFields on a JWindow which was working when I was designing the app. I was using VAJ3.5. Once I jar'd with jdk1.3.1 the first textfield would respond when I "java -jar My.jar" and the 2nd would only gain focus when i would click to another program and I would come back to the jar. And if I double clicked then both texts would not respond. I then changed to a JDialog, and everything works fine now.
I would rather use JWindow but im at a loss to explain why this would happen. Can anyone shed some light?
Thank you for your time

Try this basic troubleshooting fix:
1 - delete the IDVD preference file, com.apple.iDVD.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete IDVD'S cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iDVD folder.
3 - launch IDVD and try again.
NOTE: In Lion, Mountain Lion and Mavericks the Home/Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and press the Return key - 10.7: Un-hide the User Library folder.
If you're running Mavericks, 10.9, go to your Home folder and use the View ➙ Show View Options menu to bring the this window:
It the above doesn't help Boot into Safe Mode, Mac OS X: Starting up in Safe Mode, and try iDVD there. Then reboot normally and try again.

Can not focus or edit on JTextField on SuSe Linux 9.1

Hi,
I am trying to debug a strange problem with JTextField on SuSe Linux 9.1.
The problem is that the mouse click can not gain focus to the JTextField
in a very high frequency. Once problem occurs, the keyboard tab also
does not work. The problem does not happen all the time.
I wrote a simple event listener that dump out events that confirm that
the TextField got the mouse click event.
We are using JDK1.4.2_05.
The same piece of code works fine with Windows XP and RedHat.
I would greately appreciated if you have any suggestion to debug this
issue.
Thanks,

The first thing to do is identify which of the two rows with the same key value are correctly referenced by rows in other tables. If all referencing rows relate to only one of the errant pair then you can insert the non-key values from the other
one into a new row, and then delete the original 'bad' row. If you find that there are rows in referencing tables which relate to each of the errant pair, then, after copying the non-key values from one into a new row and deleting the 'bad' original,
you'll need to change the foreign key values in those rows in any referencing tables which related to the 'bad' original to the value of the primary key in its replacement row. You'll need to delete the relationship before doing any of this of
course.
Once you've done the above I'd then be inclined to copy the table to a new one under a different name, delete the original table, rename the copy to the original name, and then re-create the enforced relationship. Finally, compact and repair the database.
