Access to an JInternalFrame
Hi,
I have a JFrame with aJDesktoPane. I want to access the current selected JInternalFrame from an "Edit" button within my JMenuBar in my JFrame.
Does anyone know, how to get the currently active JInternalFrame?
actionPerformed(ActionEvent e)
JInternalFrame[] allFrames = desktop.getAllFrames()
for(int i = 0, size = allFrames.length; i < size ; i++)
if(allFrames.isSelected())
System.out.println("the current selected frame is "+allFrames[i])
break;

Please, URGENT! Access objects in JInternalFrame
I need to access a specific object in a JInternal frame, e.g. a JTextField. I have different istance of the same JInternalFrame that contain a JTabbedPane with different pane. I use the getSelectedFrame() method to get the JInternalFrame handle of the focused JInternalFrame, but I don't know how to reference the JTextField contained in one of the pane contained in the JTabbedPane contained in the JInternalFrame.
please help me soonwell if the JInternal frame is in its own class file then in that same file make a method like
public JTextArea getTextArea(){
return this.<JTextArea>;
that way you can access it like
getSelectedFrame().getTextArea().setText("wadadadadadadadadada");
or summin like that -
Access and set title of JInternalFrame from contentPanel
I know the answer is probably very easy but how do I dynamiically access and set the title of the JInternalFrame from a JPanel in the contentPane? The problem is the JPanel does not have a direct reference stored to the JInternalFrame

JInternalFrame drawing problem.
Hi gurus
Please could you help with a java problem that I cant find an answer to over the net:
I have a JDesktop which contains multiple JInternalFrames. On one JInternalFrame i have attached a JPanel on which to draw on. I have multiple threads (simple ball shapes) that need to be drawn onto the JPanel and have left it up to the indivual threads to draw themselves (as opposed to using paintComponent in the JPanel class). The drawing on the JInternalFrame works perfectly fine.
The problem arises when the other JInternalFrames are placed on top of each other - the balls are drawn over the top most JInternalFrame. What am i doing wrong? I have attached snippets of the code:
public class Desktop extends JFrame implements ActionListener
public Desktop()
setTitle("Agent's world");
setSize(w,h);
setDefaultCloseOperation(EXIT_ON_CLOSE);
JDesktopPane desktop = new JDesktopPane();
setContentPane(desktop);
/************* Agent *************/
JInternalFrame agents = new JInternalFrame("Agents War", true, false, true, false);
agents.reshape(0,0,(int)((w/3)*2),h);
Container contentPane = agents.getContentPane();
canvas = new AgentPanel(agents);
contentPane.add(canvas);
/************* Button *************/
JPanel buttonPanel = new JPanel();
ButtonGroup buttonGroup = new ButtonGroup();
JButton start = new JButton("START");
start.addActionListener(this);
buttonPanel.add(start);
contentPane.add(buttonPanel, "North");
agents.setVisible(true);
desktop.add(agents);
//sets focus to other frames within the desktop
try
agents.setSelected(true);
catch(PropertyVetoException e)
//attempt to refocus was vetoed by a frame
/** Method to listen for event actions, i.e. button clicks **/
public void actionPerformed(ActionEvent event)
//passes through 'this' to allow access to the getList method
Agents agent = new Agents(canvas, this);
agent.start();
public class Agents extends Thread
public Agents(AgentPanel panel, Desktop desktop)
panel =_panel;
desktop = _desktop;
setDaemon(true);
/** Moves the agent from a spefic position to a new position **/
public void move()
Graphics g = panel.getGraphics();
Graphics2D g2 = (Graphics2D)g;
try
//set XOR mode
g.setXORMode(panel.getBackground());
//draw over old
Ellipse2D.Double ballOld = new Ellipse2D.Double(i , j, length, length);
g2.fill(ballOld);
i++;
j++;
if(flag == true)
//draw new
Ellipse2D.Double ballNew = new Ellipse2D.Double(i , j, length, length);
g2.fill(ballNew);
g2.setPaintMode();
finally
g.dispose();
/** Activates the Thread **/
public void run()
int i = 0;
while(!interrupted() && i<100)
try
for(i = 0 ; i <100 ; i++)
//draw ball in old position move();
sleep(100);
catch(InterruptedException e)
public class AgentPanel extends JPanel
/** local copy of internal frame */
private JInternalFrame frame;
public AgentPanel(JInternalFrame _frame)
frame = _frame;
setSize(frame.getWidth(), frame.getHeight());
setBackground(Color.white);
public void paintComponent(Graphics g)
super.paintComponent(g);
Thank you in advance.

Undecorated JInternalFrame becomes decorated by itself.
Hi,
I’m facing a problem with JInternalFrame implementation. I have made the JInternalFrame undecorated, so that the title bar and border of the JInternalFrame gets removed. The problem occurs in the following scenario.
*1) Execute the program in a Windows 7 machine.*
*• At this point the JInternalFrame remains undecorated.*
*2) Access the Windows 7 machine using remote desktop sharing from another machine.*
*• Now the title bar and border of the internal frame becomes visible.*
This issue occurs only in Windows 7 machine, and not in Windows XP. You can access the Windows 7 machine using remote desktop sharing from another Windows 7 machine or Windows XP machine.
Also if you access the machine using remote desktop sharing first, and then execute the program, the JInternalFrame remains undecorated.
Steps to reproduce
Step 1: Execute the application in a Windows 7 machine.
Step 2: Access the Windows 7 machine using remote desktop sharing from another Windows 7 or Windows XP machine.
Step 3: Check the GUI of the application
Result :- The title bar and border of the undecorated JInternalFrame becomes visible.
If anyone has faced this issue or if anyone has a solution for this issue, kindly share your thoughts.

}Thanks a lot for that lead Walter.
Actually when I tried to override updateUI(), I got a NullPoinerException. Instead of that, I tried overriding the paintComponent() method, did the undecoration part in that method and, and called super.paintComponent(g) inside the method. Then the issue was resolved.
Once again, thanks for the quick reply. -
A question on JInternalFrame of Swing. Let see the code
Hello everybody,
I am setting up a Frame that contains 2 JInternalFrames in its desktopPane. The first JInternalFrame is to show the map. The second one have some check box. What I wanna do is, when I check the CheckBox in the second JInternalFrame, after getting the result from Database, it show the result on Map. The result will be some red ellipses on the first JInternalFrame.
The code work well with Database. But I really need your help to do with the event on InternalFrame

Communicate between two JInternalFrames
Hello all.
I have a swing application where I have a JFrame that encompasses two JInternalFrame's.
We'll call them AppFrame, IFrame and StatusFrame
I am attempting to create a running log of messages (Strings) that will be shown in StatusFrame.
The IFrame will be generating these messages that need to show up on StatusFrame.
Both are invoked by AppFrame.
My question is: How do I pass the message from IFrame to StatusFrame? I imagine it will involve some object sharing, but my brain is fried.
If anyone could point me in the right direction, I would appreciate it.
Thanks!Thanks for bringing me up to speed!
Just a couple of questions...please forgive me, I am very new to homegrowing listeners.
1) When you said "which should save off the listener in some collection", how would you go about taking StatusListener listener and storing it, and, how do I access it to send a status? Do I access it by using:
listener.statusChanged("message")?
2) When you say "use the addStatusListener method of the iframe to add itself", just for clarification, I assume you mean something to the effect of:
iframe.addStatusListener(statusFrame) , right?
Again, thank you for helping me understand. I'm not quite there, but I am a lot further than I was yesterday.

/code]You don't want your Main class to have accessor methods or public variables... that's the worst dependency you can have.
Anyways, think in terms of objects. When one object has a reference to another object, it can access all of its public data and methods.
I'd recommend reading up on the basics:

Hello.
I have been working a little with BC4J in Form (JFrame) and it works , now I want to use JInternalFrame ina JDesktopPane.
I created a JFrame from JClient wizard and instead extends JFrame I modified the code to extends from JInternalFrame, also comment the constructor because don have listener, but when I want to put some Data Control from de palette , I dont have option to do it.
Could anybody help me please? thanks a lot!Hello, thanks for the help, I do exactly what you say. Well now the situation is when I want to close the internalFrame in the case that JFrame there is no problem because it close with System.exit(0) but when I try to close an internalframe I get a problem. I use an JFrame that implements InternalFrameListener and invoke an Internalframe called MyInternalFrameUsuarios now, when I close the internalFrame I put in the listener of closing :
public void internalFrameClosing(InternalFrameEvent e) {
System.out.println("Internal frame closing");
MyInternalFrameUsuarios finalFrame = (MyInternalFrameUsuarios)e.getInternalFrame();
int action = finalFrame._popupTransactionDialog();
if (action != JOptionPane.CLOSED_OPTION)
finalFrame.panelBinding.releaseDataControl();
//System.exit(0);
I comment the System.exit because just want to close the internalFrame but the problem is that the window dont close, the content gone but the window still remain in the frame and if I try to close again the window I receive this exception :
oracle.jbo.common.ampool.ApplicationPoolException: JBO-30006: The cookie for session AppModuleDataControl:1089132867566:1 and application AppModuleDataControl is not a valid handle for application pool, mypackage1.AppModuleLocal. The cookie may not be used to access this pool instance.

Also if I open new internalFrame window and try to close the new one, this exception is generated :

Adding a button to a JInternalFrame titlebar
hi ,
i was looking for a way to add an additional button to the titlbar of my JInternalFrame , i found some very useful codes here but i still got a little problem , after i added the new button the title of my JInternalFrame becomes "..."
i would like to hear any suggestion you guys have ,
here is my code :
import javax.swing.*;
import javax.swing.plaf.basic.BasicInternalFrameUI;
import javax.swing.plaf.metal.MetalInternalFrameTitlePane;
import java.awt.*;
public class InternalFrameTest extends JFrame{
public InternalFrameTest() {
super();
JInternalFrame jInternalFrame = new JInternalFrame("InternalFrameTest",true,true,true,true);
myTitleBar(jInternalFrame);
jInternalFrame.setSize(400,400);
jInternalFrame.setVisible(true);
JDesktopPane desktop = new JDesktopPane();
desktop.add(jInternalFrame);
getContentPane().add(desktop);
setSize(500, 500);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLocationRelativeTo(null);
setVisible(true);
private void myTitleBar(JInternalFrame internalFrame){
BasicInternalFrameUI basicInternalFrameUI = (BasicInternalFrameUI)internalFrame.getUI();
MetalInternalFrameTitlePane northPane = (MetalInternalFrameTitlePane)basicInternalFrameUI.getNorthPane();
JButton iconifyButton = null;
JButton maximizeButton = null;
JButton closeButton = null;
Component[] components = northPane.getComponents();
for( int i=0; i < components.length; i++ ){
if( components[i] instanceof JButton ){
if( i == 0 ){
iconifyButton= (JButton)components;
}else if( i == 1 ){
maximizeButton= (JButton)components[i];
}else{
closeButton= (JButton)components[i];
northPane.remove( components[i] );
//create the additional button
JButton additionalButton = new JButton("+");
additionalButton.setFont(new Font("Arial",Font.BOLD,9));
additionalButton.setPreferredSize(new Dimension(14,14));
additionalButton.setMargin(new Insets(0, 0, 0, 0));
//create a new buttons panel
JPanel buttonsPanel = new JPanel();
buttonsPanel.setOpaque(false);
buttonsPanel.setMaximumSize(new Dimension(-1, 14));
//adding the buttons to the buttons panel
buttonsPanel.add(additionalButton);
buttonsPanel.add(iconifyButton);
buttonsPanel.add(maximizeButton);
buttonsPanel.add(closeButton);
//adding the panel to the north pane of the internal frame
northPane.setLayout(new BorderLayout());
northPane.add(buttonsPanel,BorderLayout.EAST);
public static void main(String[] args) {
new InternalFrameTest();
thanks in advance ,
ozIn general, it is very bad practice to access internal structures of UI delegates. Every time you find yourself casting getUI() result to a specific class and accessing the internal components, you are digging a very nasty hole. In this case, just adding the button is not enough - the internal frame title pane has a custom layout manager that knows nothing about it.
You will have to dig much deeper and create your own UI delegate for internal frames to handle all the cases (including theme support, rollover effects, layout and RTL). Another option is to use Substance LAF that provides an API to add custom buttons to title panes [1]. This example shows how to do this for top-level frames, but the same would work for internal frames as well.

Enable/Disable JMenu in JFrame on click of button in JInternalFrame
Hello there. Could anybody help me out of the situation?
I am trying to enable/disable JMenu of JFrame on click of a button which is in JInternalFrame.
I want to set JMenu(this is in JFrame).setEnable(true) in ActionPerformed() of JInternalFrame, but JFrame and JInternalFrame are the different classes and I do not know how I can access JMenu in main frame.
How should I write something like mainframe.menu.setEnabled(true) from internal frame?
For JInternalFrame window action, there is JInternalFrameListener, but this is not relevant for my situation because I am trying to control on click of a button.
Can anybody suggest a solution?// Main Frame
public class MainFrame extends JFrame
public MainFrame()
InternalFrame l_int = new InternalFrame(this);
//try to initiate internal frame like this
public void activateMenu()
menuBar.setEnabled(true);
public static void main(String args[])
MainFrame mainframe = new MainFrame();
// Internal Frame
public class InternalFrame extends JInternalFrame
private MainFrame m_mainFrm = null;
public InternalFrame(MainFrame a_objMainFrame)
//your own code
m_mainFrm = a_objMainFrame;
public void actionPerformed(ActionEvent a_objevent)
if(m_mainFrm != null)
m_mainFrm.activateMenu();
}try this.. hope this will help you

How can access a data member in constructor
hello,
I want to know that How can access data member of class in constructor of same class
Thnx
RakeshYou need to point it at
some object, like you do in newFile. What's in
newFile is fine, but newFile isn't called beforethe
doc= line.actually i have this a bigger program what i have
send before. i m getting a object of JEditorPane in
newFile() and asssigning it to epMain.
Thats why i want to access epMain's that value what i
have setted in newFile so i dont created a new object
and assigned in epMain as like
this.epMain= new JEditorPane();so how I can access epMain's that value what i have
setted in newFile()
here is actual newFile method
public void newFile()
Component comp=newEditPane();
JInternalFrame iFrame=makeIF(comp,"Untitled");
iFrame.setVisible(true);
if(iFrame.getDesktopPane().getSelectedFrame()!=null)
selectedFr=iFrame.getDesktopPane().getSelectedFrame();
Container iContent = selectedFr.getContentPane();
JScrollPane
jsp=(JScrollPane)iContent.getComponent(0);
JEditorPane
e=(JEditorPane)jsp.getViewport().getView();
this.epMain=e;
Hmmn... Rakesh you're so makulit. Do you know what null pointer means? Here read the docs API,
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/NullPointerException.html
You're displaying html using JEditorPane, why dont you try org.jdesktop.jdic.browser.WebBrowser?

Okie? ^_^

Running Commands in JInternalFrame from DesktopPane
I have a desktop Pane and within it, I am successfuly able to run various JInternal Frames.
The DesktopPane has its own menu bar and the JInternal Frame has it's own Menu Bar. This has a very bad look on the overall appearance of the package.
I want to combine both of these menu bars so that it appears on the DesktopPane.
But I am odds at figuring out how to run a particular command from the menu bar of the desktop pane (like inserting an image inside the text pane in the Internal Frame)
Any suggestions on where I should start?hello,
just as poop said, create an object of the active frame by
JInternalFrame frame = desktopPane.getSelectedFrame();//create an object of the active frameonce u have the object u can access its variables and methods as long as they are not protected (encapsulated). use the dot notation to access the variables or methods, i.e. frame.someVariable; or frame.someFunction();
the other way (which is not so efficient) is by creating an interface file, store all variables used in the application there and implement the interface in all files, that way u can access the variables as well as methods but just as i said this method is not so efficient, it can work as a workaround.
hope makes sense.

Simple JInternalFrame question.
Pro's,
Would there be any reason why a JInternalFrame would not show up when accessed through a mouse click on a menu. I can bring it up perfectly when running it as a stand alone JFrame. It is not showing up when I change it to a JInternalFrame. I know and understand that the problem is while changing it from a JFrame to a JInternalFrame but I want to pin point it..:( and know what I need to make the JInternalFrame work the same as a JFrame. I searched the archives and 'googled' about the problem but could not find anything. Any suggestions/input will be very helpful. TIA.
Misty.Thanks a lot for your response camickr
JFrames are displayed on a desktop.Yes, makes sense.
JInternalFrames are added to JDesktopPaneAlready did that.
The desktop pane is added to your JFrameYes.
I am still not able to display my JInternalFrame...Just does not make sense. Will keep trying away.
Thanks again for the input.
Misty.
