Help in jwindow

hi there
i want to build an application with jwindow but i have a problem , the jwindow doesn't have a taskbar button how can i create one

I am not sure if there is no way (I am not an expert) but I would think that it might be easier to change JFrame to behave the way you need (like a JWindow). But since I don't know what you are trying to do or if it is possible to get the taskbar or how hard it would be, I am just guessing / suggesting. :-)

JFrames Parent-Child Relationship

Hi Experts,
I m facing a problem. I have one JFrame in which one JButton is added. On click of this JButton one other JFrame open up or we can say pop up.
Now I want that user can not click on parent JFrame ( which open new JFrame ) until he close this new JFrame.
Like, for example, while viewing html page when we get Alert, we have to click on it to go back to page, without clicking on it we are not allowed to go back to page.
Same functionality I want in Swing.
Anyone can help me ? ? ?

Thanx for your reply.
But problem is I want to add so many components in my new opening window like textfield,buttons,check box ..etc.
And as i know this is not possible with JDialog , so is there any option remaining ?
I am trying to do it with the help of JWindow by using it's method getOwner() and constructor JWindow(Frame owner) or JWindow(JWindow owner) ..i am trying ...i m not sure.
Could anyone focus on this issue ???

Urgent Help jdk 1.4.2 JWindow and Text Field

Go thgh this code pls
import java.awt.*;
import javax.swing.*;
class Test1 extends JWindow
     TextField tf;
     public Test1()
          Container contentPane = getContentPane();
          contentPane.setLayout(new FlowLayout());
          tf = new TextField(10);
          contentPane.add(tf);
public class Test extends Test1
     public static void main(String[] args)
          Test1 t = new Test1();
          t.setSize(300,200);
          t.show();
when the above application is compiled and run using jdk1.4 0r above the text field gets disabled. ie nothing gets entered in the text field.
However if i extend JFrame instead of JWindow then everything is fine.
Also note that the same code compiles and runs perfectly on 1.3.1 ie even if i extend JWindow i am able to enter text in text field.
Pls help asap

this works because theres an owner frame behind the window:import java.awt.*;
import javax.swing.*;
class Test extends JWindow
     static TextField tf;
     public Test(JFrame owner)
          super(owner);

          JFrame frame = new FrameForWindow();
          Test t = new Test(frame);
          t.setSize(300, 200);

JWindow JTextArea Issue... Help

Hello guys and gals,
I'm sure this issue I'm having is very common here to us programmers and people have asked this question several times.
I'm using JWindow right now and I have a JTextArea that's not editable at all even though I've set it to be editable.. All I can do is setText to be there... It must be a bug or something..
I will not convert to JFrame though it's easier to do so. JWindow is needed. Is it possible to my JTextArea editable so I can continue to program or am I just wasting time? Can anyone explain to me in simple terms to fix this issue? Maybe my code is incorrect.. Here's my entire code:

JWindow closing with ALT F4 leaving child components help please.....

Hi all

Hi!
How did you created your frames / dialogs?
You must give the reference of the JWindow instance as owner for your child frames...
I hope this helps you,

Help: How to use JWindow as Popup

Hi there,
I am developing a program & I wanted to design it with a screen like the Mac OS (tiger?) desktop. That is menu (button bar) at the bottom of the screen (the program's screen - Not the OS).
I thought I should use a JWindow to do it.
HOW I WOULD LIKE THE POPUP TO BEHAVE:
- Only appears when a user moves the mouse towards the bottom of the screen.
- To disappear (hide) when the user clicks somewhere else on the screen [when focus is lost(?)]
- To change its position relative to the program. That is, if the program is resized etc...
I NEED YOUR HELP ON
The design issues I should take into consideration. I mean interfaces I should implement etc...
Thanks in advance.
Yours,
Me

Okay, sorry for the late reply, I dont go on the net much.
With the focus issues, it could be very tricky to know when exactly the Window has lost focus cause a component within the window could still have the focus, hence the window would be in focus.
One way, could be to add a common FocusListener to all the components within the window by using a recursion method, and allow this FocusListener to determine when all the elements within the window have lost focus, so as to call the window hiding function
public void addFocusListener(Component c, FocusListener fl) {
c.addFocusListener(fl);
if(c instanceof Container) {
 Container cn = (Container)c;
 for(int i = 0; i < cn.getComponents().length; i++) {
 addFocusListener(cn.getComponent(i), fl);
// also the focus listener could be like this
class FocusChecker implements FocusListener {
 public void focusLost(FocusEvent e) {
 Component source = (Component)e.getSource();
 if(popupWindow.isAncestorOf(source)) {
 if(!popupWindow.isFocussed()) { // check if the window has a focussed component
 moveWindowIntoHiding(); // call the method to hide to window
}This is just a general guideline. Think around this to hide the window when it looses focus

How can I make a default border for a JWindow?

I have a JWindow object that is created when a button is pressed in a JFrame. I want the JWindow to have the same type of border as the JFrame from which it's created. However, the JWindow is not created automatically with a border as the JFrame is, so I don't know how to set the border abstractly so that whatever border is used for the JFrame, per he default L&F, will also be used for the JWindow.
I tried grabbing the border object from the JFame instance itself, but there is no such field in JFrame or any of its ancestor classes. I looked at UIDefaults, but I have no idea how this class can be used to get what I want. For example, if I use UIDefaults.getBorder(Object obj), what do I specify for the argument?
I'd be happy with an abstract or a concrete solution. That is, either using the default Border for top level containers in the current L&F, or by grabbing an actual Border instance from a JFrame object.

Also, I'm curious why you said that JFrame is not a swing component.A Swing component extends JComponent. Basically this means that all the painting of the component is done in Java. You can add Borders to any Swing component. It is called a light weight component. A light weight component cannot exist by itself on the window desktop.
JFrame, JDialog and JWindow are top level components. They can exist on their own on the windows desktop because essentially they are Windows native components. They have been fancied up to make it easy for you to access and add other Swing components to it which is why they are found in the swing package.
A Windows border is not the same thing as a Swing Border and there is no way to access the native windows border and use it in a Swing application (that I know of anyway). Swing Borders are not used in a normal JFrame, the Windows border is used. You can however, turn off the use of Windows decorations and use Swing painted decorations. Read the tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/frame.html#setDefaultLookAndFeelDecorated]Specifying Windows Decorations. However, this doesn't really help you with your Border problem. If you look at the source code for the FrameBorder, you will find that the "blue" color of the Border is only painted for "active" windows and a JWindow can never be the active window, only the parent JFrame or JDialog is considered active.
Here is a simple program for you to play around with:
import java.awt.*;
import javax.swing.*;
import javax.swing.border.*;
public class FrameDecorated
     public static void main(String[] args)
          JFrame.setDefaultLookAndFeelDecorated(true);
          JFrame frame = new JFrame();
          frame.setDefaultCloseOperation( JFrame.DISPOSE_ON_CLOSE );
          frame.setSize(300, 300);
          frame.setVisible(true);
          Border border = frame.getRootPane().getBorder();
//          Border border = UIManager.getBorder( "RootPane.frameBorder" );
          System.out.println( border );
          JWindow window = new JWindow(frame);
          JPanel contentPane = (JPanel)window.getContentPane();
          contentPane.add(new JTextField(), BorderLayout.NORTH);
          contentPane.setBorder( border );
          window.setSize(300, 300);
          window.setLocationRelativeTo( null );
          window.setVisible( true );
          System.out.println("Window:" + window);
          Window ancestor = SwingUtilities.getWindowAncestor(contentPane);
          System.out.println("Ancestor:" + ancestor);
          System.out.println(ancestor.isActive());
          System.out.println(frame.isActive());
}

Help needed, Createing Dynamic User input

Hello,
I am attempting to create some dynamic user input by "predicting" what the user requires in a text box.
For example if the user enters "Smi" I have a select list pop up which gives the user all options that begin with "Smi".
I am able to achieve the popups but the interface is quite jerky and not terribly responsive I am trying to solve this by using a thread which starts and stops when new input is received but it is still not quite right.
The program uses a Sorted TreeSet to hold the data (I thought this would give me a quick search time) and a simple interface at this stage.
Any help would be fantastic
Thanks in advance :P

Help needed, Providing Dynamic User input

Hello,
I am attempting to create some dynamic user input by "predicting" what the user requires in a text box.
For example if the user enters "Smi" I have a select list pop up which gives the user all options that begin with "Smi".
I am able to achieve the popups but the interface is quite jerky and not terribly responsive I am trying to solve this by using a thread which starts and stops when new input is received but it is still not quite right.
The program uses a Sorted TreeSet to hold the data (I thought this would give me a quick search time) and a simple interface at this stage.
Any help would be fantastic
Thanks in advance :P

Problem with JWindow

Hi all,
I have a very important question....
I created a small application and when i launch it, i'd like to have a JWindow displayed on my screen only during 5 seconds.... So i run my application, my JWindow is displayed during 5 seconds and then the application "really" begins.
But how do i have to proceed to have my JWindow displayed only during 5 seconds and then close automatically???
Thanx very much for helping....

Jpopupmenu visibility problem with JWindows

Hello,
BACKGROUND:
I am attempting to implement a feature similar to one found in the netbeans IDE for a programming editor I am helping to write. The feature is an autocomplete/function suggestion based on the current word being typed, and an api popup for the selected function.
Currently a JPopupMenu is used to provide a list of suggested functions based on the current word being typed. EG, when a user types 'array_s' a JPopupMenu pops up with array_search, array_shift, array_slice, etc.
When the user selects one of these options (using the up/down arrow keys) a JWindow (with a jscrollpane embedded in it) is made visible which displays the api page for that particular function.
PROBLEM:
The problem is that when a user scrolls down the JWindow the JPopupmenu disappears so he user cannot select another function.
I have added a ComponentListener to the JPopupMenu so that when componentHidden is called I can do checks to see if it should be visible and make visible if necessary. However, componentHidden is never called.
I have added a focuslistener to the JPopupMenu so that when it loses focus I can do the same checks/make visible if necessary. This function is never called.
I have added a popupMenuListener but this tells me when it is going to make something invisible, not actually when it's done it, so I can't call popup.setVisible(true) from popupMenuWillBecomeInvisible because at that point the menu is still visible.
Does anyone have any suggestions about how I can scroll through a scrollpane in a JWindow whilst still keeping the focus on a separate JPopupMenu in a separate frame?
Cheers

The usual way to do popup windows (such as autocomplete as you're doing) is not to create a JPopupMenu, but rather an undecorated (J)Window. Stick a JList in the popup window for the user to select their choice from. The problem with using a JPopupMenu is just what you're experiencing - they're designed to disappear when they lose focus. Using an undecorated JWindow, you can control when it appears/disappears.
See this thread for information on how to do this:
http://forum.java.sun.com/thread.jspa?threadID=5261850&messageID=10090206#10090206
It refers you to another thread describing how to create the "popup's" JWindow so that it doesn't steal input focus from the underlying text component. Then, further down, it describes how you can forward keyboard actions from the underlying text component to the JWindow's contents. This is needed, for example, so the user can keep typing when the autocomplete window is displayed, or press the up/down arrow keys to select different items in the autocomplete window.
It sounds complicated, but it really isn't. :)

HELP !! XP look and feel ...

how can i make my frame have an XP look and feel ??????
please help me in details , cause i haven't done this look and feel thing before ??? thanks in advance ..

You need to change to the windows LnF which is not the default. The
following code will do it for you. Note that it will only work if your
using Windows XP.
* LookAndFeel.java
public class LookAndFeel {
    public static final String MAC_CLASS = "com.sun.java.swing.plaf.mac.MacLookAndFeel";
    public static final String METAL_CLASS = "javax.swing.plaf.metal.MetalLookAndFeel";
    public static final String MOTIF_CLASS = "com.sun.java.swing.plaf.motif.MotifLookAndFeel";
    public static final String WINDOWS_CLASS = "com.sun.java.swing.plaf.windows.WindowsLookAndFeel";
    public static final String GTK_CLASS = "com.sun.java.swing.plaf.gtk.GTKLookAndFeel";
    public static final String KUNSTSTOFF_CLASS = "com.incors.plaf.kunststoff.KunststoffLookAndFeel";
    public static boolean updateLookAndFeel(String currentLookAndFeel, java.awt.Component parent) {
     try {
         javax.swing.UIManager.setLookAndFeel(currentLookAndFeel);
            if(parent != null) {
                javax.swing.SwingUtilities.updateComponentTreeUI(parent);
     } catch(Exception ex) {
         System.out.println(ex);
            return false;
        return true;
}To get it to work do the following:
    LookAndFeel.updateLookAndFeel(LookAndFeel.WINDOWS_CLASS, this);where this represents your JWindow or JFrame.
Hope it helps.
James.

Minimize/Maximize a JWindow

Hi everyone,
I created an application that derives JWindow instead of the usual JFrame as the parent class of the application. This works fine but I have a following problems listed below that I have not solved yet.
1. Is it possible to implement Maximize/Minimize to a JWindow-derived application?
2. Is it possible to add a Taskbar button that will be displayed in the taskbar area of Windows OS once the application is run?
Thank you in advance.
Regards,
Ferdie

2. Is it possible to add a Taskbar button that will be

I had a problem similar to this before, and what I did was to have a small JFrame that was always behind the JWindow. This causes a button to show up in the taskbar of Windows. also when you have a button on the JWindow for say minimizing it, what you actually do is minimize the JFrame behind it and set the JWindow so its not visible. Then when you want to restore the JWindow from the taskbar, the JWindow is set visible again and the JFrame is placed behind it on the screen. You'll also have to track the user moving the JWindow and move the JFrame behind it accordingly so it is always behind it...
hope that helps you....

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
Thomas.
