I'm having a problem with a JTabbedPane I'm trying to implement.
Whenever I click on any part of the tabbed pane, the JSplitPane I have on the tab is resixing itself for some reason.
Anyone have a clue whats going on?

import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JTabbedPane; import javax.swing.JScrollPane; import javax.swing.JTextArea; import javax.swing.JSplitPane; import javax.swing.JList; import javax.swing.*; import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; public class TestFrame extends JFrame { public static void main(String[] args){new TestFrame();} TestFrame() { JTabbedPane tabbedFrame = new JTabbedPane(); tabbedFrame.addTab("Commands", makeCommand()); getContentPane().add(tabbedFrame); addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent e) { System.exit(0); } public void windowStateChanged(WindowEvent e) {} }); setLocation(100, 50); setSize(600, 500); setTitle("Tabbed Frame"); setVisible(true); } protected JPanel makeCommand() { String[] description = {"Description 1","Description 2"}; String[] commands = {"Command 1","Command 2"}; JSplitPane splitPane; JScrollPane leftScroll; JScrollPane rightScroll; JList leftList; JTextArea commandText; JPanel panel = new JPanel(); leftList = new JList(description); leftList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); leftList.setSelectedIndex(0); commandText = new JTextArea(commands[0]); commandText.setLineWrap(true); leftScroll = new JScrollPane(leftList); rightScroll = new JScrollPane(commandText); splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, leftScroll, rightScroll); splitPane.setOneTouchExpandable(true); splitPane.setDividerLocation(100); splitPane.setDividerSize(6); panel.add(splitPane); return panel; } }

Its ok,
I realised where the prob is.
I forgot to add the action listeners to the window.
I just added them in the class constructor.

Does anyone know how to keep a JWindow on top of the screen?
If I click any part of the screen the JWindow stays on top.
But if I click on any part of the JWindow, it disappears under the main JFrame, eventhough I dont implement any of the listeners.
Here's my code
public class ClassInfoWindow extends JWindow implements MouseListener, MouseMotionListener { int x, y; String[] info; ClassInfoWindow(String[] string, int xCoord, int yCoord) { info = string; x = xCoord; y = yCoord; int stringAmount = 0; while(string[stringAmount] != null){ stringAmount++; } setBounds(x, y, 200, 20 * (stringAmount + 1)); setVisible(true); setBackground(Color.black); } public void actionPerformed(ActionEvent m_event) {} public void mouseReleased(MouseEvent me) {} public void mouseEntered(MouseEvent me) {} public void mouseExited(MouseEvent me) {} public void mouseMoved(MouseEvent me) {} public void mousePressed(MouseEvent me){} public void mouseClicked(MouseEvent e){} public void mouseDragged(MouseEvent e){} public void paint(Graphics g) { Graphics2D g2 = (Graphics2D) g; ///////////////////////////// // Drawing Window Outline ///////////////////////////// g2.setColor(Color.white); g2.drawRect(0, 0, getWidth()-1, getHeight()-1); }
Any ideas ppl?

Hi,
Does anyone know how to extract all the files
from a jar file, from inside a running java program?

Yeah, what they're discussing sounds simular to my problem but most of there problems involve sun one, mine doesn't.
If worst comes to worst, and i cant solve it, i'll just have to make sure i dont try and close my application on demo day!!

A simple prog will work no problem.
Problems seem to arise with larger java progs.
I've discounted my own program as a source of the problem cause it's not only my program thats stalling.
Another possibility is that its my program thats has somehow corrupted the system, but i cant see how that could happen.
At this stage i think the only answer is to strip the comp and re-install windows 2000. At least i'll know for sure if it my application thats the prob or not.
It might be a bit drastic though.
I'll tell you about the outcome and maybe i'll have some answers in the near future!

Yeah I installed Service pack 3 about a week ago and it didn't seem to make any difference.
I'll try installing java 1.3.x but i might be using some methods that don't exist in 1.3, thus giving me a pile of errors and requiring a re-write.
The price i'll have to pay i guess.

Originally the call for the garbage collector wasn't there.
I was just trying something.
It obviously made no difference.
I really dont think its the java program because i've tried running other established java programs such as ArgoUML and that prog also causes the comp to crash when i close it.
I'm not sure what you are talking about when you mention finalisers?

I've tried viewing the task manager before and after i attempt to close the app.
It still doesnt give any clear indications as to what exactly is happening.
The stall occurs when i make any attempt to close the application. I use the following code when i'm closing the app......
frame.addWindowListener(new WindowAdapter() { public void windowClosing(WindowEvent e) {System.gc(); System.exit(0);} public void windowStateChanged(WindowEvent e) {System.out.println("Window Resized");} });
At this stage i've run completely out of ideas.

I'm using Java 1.4.1 and the OS is Windows 2000

I have, what seems like a major problem.
My java program runs perfectly but when I attempt to close the frame the computer stalls indefinitely.
I thought there was something wrong with my program but it was happening with other java programs i got off the net.
I then thought it the JVM but i uninstalled it and then re-installed it and the same problems remained.
Has anyone ever experienced this or does anyone has any ideas?

Hey ppl,
I'm trying to store the structure of a tree.
Any ideas on the best way of achieving this?

Hey everyone,
I want to be able to parse a java file using java.
I was wondering does anyone have any experience with this, or does anyone have any advice before i start?

Sorry, i meant to say that i cant get it
to open a dialog box to choose the file.
Has anyone else experienced this with
the JFileChooser. I looked up the bug page
and i couldn't find that particular bug.
Maybe i missed it?

Does anyone know of any free XMI
packages on the web?
