Moving Icon in Internal Frame?
Is it possible to add an icon into an Internal Frame, then move this
icon ("help" or question mark) onto certain topic, where a popup (and
text in it) appears? Are there any classes or methods that I should use?

Image icon on internal frame disappearing and re-appearing
I have just upgraded to jdk 1.4.1-b21 from 1.4.0_01-b03 and have noticed that after adding an Internal Frame to a desktop and moving the mouse over the image icon in the left hand corner the image disappears. The image re-appears again, once I presume, when the desktop and its frames are repainted.
Is this a bug or has something changed between the two jdk's.
Thanks.
Steve.Hi,
I attempted the Disk Utility Repair but it did not work.
So I disabled the application 'StickyWindows' and this resolved the problem.
Hope this helps. -
Hello,
I have written some custom internal frames, along with their UI's, title panes, and desktop icons. Everything seems to work fine when I'm in JBuilder and I use the "run" command, but when I compile the program and run it as a batch file, my internal frames appear as gray boxes that can't be moved or resized.

}Any ideas? I don't see how everything could work fine within the JBuilder environment and then screw up when I compile the code.
Thanks for any help.And this is how I call up the UI from my main function:

How to keep a image lways on top of internal frames?
Hello.
I have a main frame with sevral internal frames. I need to put a image on this
window that can move this image remotely.
How to keep this image always on top of these internal frames?
Is there any panel that can put on top of these internal frame?
Many thanks.Thanks for you reply and sorry for my break English.
I mean I need a image that moving on a frame which has internal Frames.
When the image meet a internal frame while it's moving, this image will go under of the internal frame , so that we can not see the image any more.
What i want to do is that let the image always keep on top of the window,
even if it meet a internal frame.
Just imagine the windows cursor. A cursor is always visible no matter where is it. -

MohanTo give focus to an internal frame, do the following (where iFrame is your internal frame):try {
iFrame.setIcon( false ); // In case it is minimized
iFrame.moveToFront(); // Make sure it is in front
iFrame.requestFocus(); // Ask for focus
iFrame.setSelected( true ); // Select it
} catch( java.beans.PropertyVetoException pve ) {

Desktop Management for Internal Frames Survey (please take a moment)
Internal frames under all look and feels currently exhibit state management that does not match generally accepted behavior.
Example: maximizing -> minimizing -> restoring an internal frame does not restore the frame back to the maximized bounds, but restores it to its normal bounds. (Expected behavior can be seen by using a MDI application under Windows.)
My question is, how many people out there are currently depending on the current implementation? If so, is this because you are currently subclassing the desktop manager or plaf code? If other reasons, please specify... Do you want this issue fixed? Any other pet peeves I'm missing? For more information you can search the bug database for bug 4424247.

Hi,
I am writing a piece of code where I want to able to choose from a menu a screen that displays multiple graphs (using Internal frames.) I am using cardlayout to bring up the various options I choose from the menu. I have simplified my program as much as possible but I still seem to be getting the same error
Exception in thread "main" java.lang.IllegalArgumentException: adding a window to a container .......
I know I shouldn't be adding a window to a container but I can't see how I can change my code so it has the functionality I desire.
Here is the code I am using
import java.awt.*;
import javax.swing.*;
public class Test extends JFrame
public Test()
JPanel card1 = new JPanel();
card1.add(new InternalFrameDemo());
getContentPane().add(card1);
public static void main(String[] args)

frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
frame.setSize(200, 200);
frame.setLocationRelativeTo( null );
frame.setVisible(true);
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
public class InternalFrameDemo extends JFrame
JDesktopPane desktop;
static final int xOffset = 30, yOffset = 30;
private JLabel graph1;
private String Graph1;
public InternalFrameDemo() {
super("InternalFrameDemo");
//Make the big window be indented 50 pixels from each edge
//of the screen.
int inset = 50;
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
setBounds(inset, inset,
screenSize.width - inset*2,
screenSize.height - inset*2);
//Set up the GUI.
desktop = new JDesktopPane(); //a specialized layered pane
createFrame(); //create first "window"
setContentPane(desktop);
//Make dragging a little faster but perhaps uglier.
desktop.setDragMode(JDesktopPane.OUTLINE_DRAG_MODE);
//Create a new internal frame.
protected void createFrame() {
MyInternalFrame frame = new MyInternalFrame();
frame.setVisible(true);
desktop.add(frame);
try {
frame.setSelected(true);
} catch (java.beans.PropertyVetoException e) {}
//Quit the application.
protected void quit() {
System.exit(0);
public void MyInternalFrame() {
System.out.println("graph1");
graph1 = new JLabel("",
new ImageIcon("../images/Graph1.jpg"),
JLabel.CENTER);
getContentPane().add(graph1);
//...Then set the window size or call pack...
setSize(500,550);
}If anyone could point me in the right direction it would be great. Thanks in advance!But I actually do not understand what that card layout thing is all about. If you want to hide/show internal frames you can simply use setVisible() and setSelected() like examplified below (I did put all code in the same file for my convenince). I have put a text in the label so that you can see that it is replaced. Using aJLabel to show an image is however a little bit weird.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
class MyInternalFrame extends JInternalFrame
private JLabel graph1;
public MyInternalFrame(String text)
graph1 = new JLabel(text,

public class InternalFrameDemo extends JFrame
private JDesktopPane desktop;

super("InternalFrameDemo");
frames = new MyInternalFrame[3];
//Make the big window be indented 50 pixels from each edge of the screen.
int inset = 50;
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
setBounds(inset, inset,
screenSize.width - inset*2,
screenSize.height - inset*2);
//Set up the GUI.
desktop = new JDesktopPane(); //a specialized layered pane
setContentPane(desktop);
frames[0] = createFrame("Hello world!");
frames[1] = createFrame("Hello again, world!");
frames[2] = createFrame("Goodbye cruel world!");
desktop.setDragMode(JDesktopPane.OUTLINE_DRAG_MODE);
setSize(500, 500);
Thread animThread = new Thread()
public void run()
for (int i = 0; i < frames.length; ++i)
final int frameId = i;
SwingUtilities.invokeLater(new Runnable()
public void run()
// Hide frame that is showing.
if (frameId != 0)
frames[frameId - 1].setVisible(false);
System.out.println("Replacing image: " + frameId);
frames[frameId].setVisible(true);
try
frames[frameId].setSelected(true);
catch (java.beans.PropertyVetoException exc)
exc.printStackTrace();
try
Thread.sleep(3000);
catch (InterruptedException exc)
exc.printStackTrace();
animThread.start();
//Create a new internal frame.
protected MyInternalFrame createFrame(String text)
MyInternalFrame frame = new MyInternalFrame(text);
desktop.add(frame);
return frame;
public static void main(String[] args)
JFrame frame = new InternalFrameDemo();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}Using lazy initialization where you postpone the creation of an internal frame until it is actually shown would be an improvement.
The setVisible/Selected() call can of course be triggered by something else in your application.
Note that changes of swing components shall be made in the EDT. -
Internal frame dragging perfermance problem in JDK1.4.1
Hi there,
When using internal frame with outline(not faster or LIVE_DRAG_MODE) property with JDK 1.4.1_01 (windows), the speed of internal frame dragging is terrible(very very slow).
The same code runs fine with JDK1.3.X, and it's performance(dragging speed) is acceptable(not very good, so so) when using JDK 1.4.0_X.
I've tried both motheds to set the property as follow, and got the same result:
desktop.setDragMode(JDesktopPane.OUTLINE_DRAG_MODE);
desktop.putClientProperty("JDesktopPane.dragMode", "outline");
But, after I commented the line: g.setXORMode(Color.white); //line Num: 279
in the class javax.swing.DefaultDesktopManager.java, the speed of dragging is very well(as same as when running with JDK1.3.X).
My qestions are:
- How can I improve the internal frame dragging performance in JDK 1.4.1_01(windows)?
- Does my testing mean to a bug in the implementation of the abstract method Graphics.setXORMode() in the JDK 1.4.1_01 windows version ?
TIA
In terms of the test case, we may just use the follows:
http://java.sun.com/docs/books/tutorial/uiswing/components/example-swing/InternalFrameDemo.java
http://java.sun.com/docs/books/tutorial/uiswing/components/example-swing/MyInternalFrame.javaAnyone know if this is registered as a bug? I couldn't find it.

Openinig internal frames by clicking menuitems
Hi,
I have been trying to open internal frames by clicking menu items but
have not been able to do so because menuitems support only action listeners and not all mouse event listeners.
Actually I wanted the event to return the frame n which the event has occured
e.g., event,getframe(), so that I could create an internal frame in the same frame.
But such kind of function is unavailable.
Kindly suggest something...the code is given below (it works perfectly)..it need a text file from which the menuitems are read. This is also given below:

AboutThe problem is that you are adding the JInternalFrame to the JFrame's contentPane when it should be added to the JDesktopPane. See your code ...
public JInternalFrame CreateInternalFrame( JFrame f )
Container cp = f.getContentPane();
JInternalFrame jif = new JInternalFrame("internal frame",true,true,true,true);
cp.add( jif ); -
Passing data from a Table in a Dialog to a Listbox in a Internal Frame
Hi All,
Currently I have 2 .java classes.
In the first class, DisplayListBox.java, it would have listboxes in it and a textbox with a button, Find.
Upon clicking on the "Find" button, it would create a dialog window and call the second class, TableSelection.java.
Therefore now, the dialog window would contain a table with all the datas.
Just in case you guys would like to know, the dialog window was created in the DisplayListBox.java class and the internal frame was being created in another cls upon clicking the menu btn.
Upon selecting a cell in the table, i'd like to pass the value to the listbox in the internal frame, how can i go about doing it?
I've got the coding for getting the value of a selected cells. However, i'm unsure of how i can pass the value retrieved to the listbox in the internal frame.
Any help and advices are gladly appreciated! (:Thanks for your reply.
However, I am quite new to java so is it possible for you to explain in details of how i should go about going it?
To start off, could you tell me:
1. Where do I create the ListSelectionListener? In the DisplayListBox.java or TableSelection.java?
Sorry for the trouble but i just picked up java so I am pretty much unsure of all these stuff.
Thanks for your help! (: -

How to get Internal frames as well as a background image in a JFrame?
Hi All,
Here's my problem. I have a JFrame with a background image that I got by overridding the paintComponent() method of a JPanel and setting as the contentPane of a JFrame. Works great.
Now what I want is to use internal frames with this Frame a la JInternalFrame classes. But you need to create a JDesktopPane object and set this as the contentPane of the JFrame to get internal frames to work, right? Is there a way for me to have my cake and eat it so I get both internal frames and a background image? Thanks!Hmmm,
so simple, why didn't I think of that? Damn Mondays!
thanks very much! -
Modal Internal Frames and JCombos
Hi,
I'm trying to create a modal internal frame as suggested in Sun's TechTip:
http://developer.java.sun.com/developer/JDCTechTips/2001/tt1220.html
All I need is to block the input for the rest of the GUI, I don't care about real modality (the setVisible() call returns immediately).
I need to have a JComboBox in my internal frame. It turns out that under JDK1.4.0/1.4.1 the list for the combo is visible only with the Windows Look And Feel, while in every other JDK version it's not visible, except for the portion falling out of the internal frame.
The code to verify this follows. Does anybody know how to fix this? I've opened a bug for it, but I was wondering if someone can help in the forum...
Run the application passing "Windows" or "CDE/Motif", click on "open" and play with the combo to observe the result.

// Associate dummy mouse listeners
// Otherwise mouse events pass through
MouseInputAdapter adapter =
new MouseInputAdapter(){};
glass.addMouseListener(adapter);
glass.addMouseMotionListener(adapter);

InternalFrameEvent e) {
glass.setVisible(false);

} catch (Exception e) {
System.err.println("Couldn't get specified look and feel ("
+ lookAndFeel
+ "), for some reason.");
System.err.println("Using the default look and feel.");
e.printStackTrace();Hi,
Had exactly the same problem. Seems there are plenty of similar problems all related to the glass pane, so have solved the problem here by putting the event-blocking panel onto the MODAL_LAYER of the layered pane, rather than replacing the glass pane. Otherwise pretty much the same technique - you may need a property change listener to track changes in the size of the layered pane
something like ...
layer = frame.getLayeredPane();
glass.setSize (layer.getSize()); // will need to track size
glass.add (modal);
layer.add(glass, JLayeredPane.MODAL_LAYER, 0);
I've modified the original examples so the frames can be re-used so you may have to play around with the example a bit
Hope it helps
cheers. -
How to set my own icon for java frame ??
I create a java class it extends JFrame. I want to change default icon on the left_top corner and using my own icon. It is a --.gif file. How to do it. When I try to modify it using setIconImage( Image image), I met problem. I cann't new Image("--.gif"). I don't know how to create a Image object using a string(file name). I try to use ImageIcon , but it is not image obj. Thanks. Gary
According to the documentation setIconImage does the following: Sets the image to be displayed in the minimized icon for this frame. Not all platforms support the concept of minimizing a window.
So,
1) It does not change the icon in the top-left corner
2) It does not work on all platforms. -
