Multiple JScrollPanes in a singe JFrame

Hi
I want both JPanels to scroll. Pretty simple code, just add 9 buttons to two JPanels, out the JPanels in JScrollPanes and put the JScrollPanes in the JFrame. I've tried resizing the JFrame and setSize for the Panels/ScrollPanes but I can only get the top (doesn't matter which panel is added first) of the JFrame to show the scroll bar. The bottom Panel doesn't show the scroll bar.

Multiple Layouts in a single JFrame

Hi,
Is it possible to have multiple layouts in a single JFrame ? What I need to do is that I need to have following components in a SINGLE content pane of a JFrame:-
A) 2 Labels
B) 1 Button
C) 1 4x4 Grid of buttons
Now implement (C) I need to use GridLayout for nide grid like looks like
mContentPane.setLayout(new GridLayout(4,4));
But (A) and (B) obviously shouldn't be part of Grid. So I assume I need to use different layout in the same content pane. Any idea how can I accomplish this ?
Thanks

Urgent ! How to add multiple JToolBars in a single JFrame

How to implement multiple JToolBars in a single JFrame
or what is the concept behind floating toolBars.If anybody can help me ,Thisis very urgent

If you insist on multiple toolbars, use the following code:
JToolBar tb1 = new JToolBar();
//add stuff
JToolBar tb2 = new JToolBar();
//add stuff
//put the toolbars on the top of the window
JPanel toolbars = new JPanel(new BorderLayout());
toolbars.add(tb1, BorderLayout.NORTH);
toolbars.add(tb2, BorderLayout.CENTER);
getContentPane().add(toolbars, BorderLayout.NORTH);Stephen

Multiple JScrollPanes in one window

Hi.
I've been trying to figure out how to make multiple scrollable text areas in one window. I'm trying to use JEditorPanes for the text areas so that they can display html. Does anyone know how I can make multiple scrollable JEditorPanes appear side by side in one window? I tried just adding many JScrollPanes to the window, but that doesn't seem to work - it only displays the first one.
Thanks.

Just to help since no one's said anything for so long.
The only way I know how may be to use a JSplitPane and add the components to the splitpane. This allows for resizing but I'm not very sure if it will exactly resize the components in them
Check the Java Demos in your SDK (Swing Set 2) I believe the demo splitpanes should give you enough go ahead to start using split panes effectlvely

How do I add multiple JInternalFrames to 1 main JFrame

It may seem like a silly question but I'd really appreciate any help offered. Sample code might be of assistance.
Thanks people :-)

It's very simple. Create a JFrame,
then create separate classes for each JInternalFrame (here: TFrame, SFrame, GFrame)
Here's some code:
public class GWorkBench extends JFrame {
public GWorkBench() {
//Set up the GUI.
desktop = new JDesktopPane(); //a specialized layered pane
setContentPane(desktop);
setJMenuBar(createMenuBar());
protected JMenuBar createMenuBar() {
JMenuBar menuBar = new JMenuBar();
JMenu menu = new JMenu("Modules");
menu.setMnemonic(KeyEvent.VK_D);
JMenuItem menuItem1 = new JMenuItem("Data Entry");
JMenuItem menuItem2 = new JMenuItem("Search Module");
JMenuItem menuItem3 = new JMenuItem("Generation Module");
menuItem1.setMnemonic(KeyEvent.VK_E);
menuItem2.setMnemonic(KeyEvent.VK_S);
menuItem3.setMnemonic(KeyEvent.VK_G);
menuItem1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
createTFrame();
menuItem2.addActionListener(new ActionListener() {
     public void actionPerformed(ActionEvent e) {
          createSFrame();
menuItem2.addActionListener(new ActionListener() {
     public void actionPerformed(ActionEvent e) {
          createGFrame();
menu.add(menuItem1);
menu.add(menuItem2);
menu.add(menuItem3);
menuBar.add(menu);
return menuBar;

Accessing multiple instance of the same JFrame.

Hi, I'm hoping someone out there can help. I'm a student desperatly trying to finish my discertation in time, I'm making an RMI chat application, everything works fine except for one thing.
If a client sends a message to another client and they have one or more conversation windows open at that time, the correct conversation window is not selected to display the message.
e.g 'Team one' sends a message to 'Team Two', who has windows open for both 'Team One' and 'Team Three'.
The conversation window is a seperate class and everytime a client creates a new conversation, a new instance of this is created.
To group all the client windows together I've created an array of client windows and every new instance is added to this array.
public static ClientWin[] group = new ClientWin[10];
public void NewWindow(Server serv, String WhoTo, String Name){
group[count] = new ClientWin(serv, WhoTo, Name);
count++;
} This works fine, new conversation windows are created fine but when I try to access something within the array e.g
group[count].transcript.append(msg); the correct transcript in the corresponding JFrame in the ClientWin array is never selected and infact, every instance within the array appears to correspond with the last JFrame instance when I've looped through the array checking values.
Any help will be greatly appreciated, this is killing my head. Thank you.
Matt

Thanks, I thought that was what I was doing, thats what I intended anyway.
The ClientWin class is my own class which extends JFrame.
The ClientWin[] group = new ClientWin[10]; is the arraylist you refer to, at least I wanted it to be.
And I check group.whoTo currently to see you the window is for and the group array is the arraylist you reffer to.
However with doing this (prob just a stupid mistake) I can't send a message to the corresponding window in the array and in fact every item in the array is the same as the last window created.
Thanks

Zoom Issues with JScrollPane

Hello all,
I have ran into an issue with zoom functionality on a JScrollPane.
Here is the situation (code to follow):
I have a JFrame with a JDesktopPane as the contentpane. Then I have a JScrollPane with a JPanel inside. On this JPanel are three rectangles. When they are clicked on, they will open up a JInternalFrame with their name (rect1, rect2, or rect3) as the title bar. Rect3 is positioned (2000,2000).
I have attached a mousewheel listener to the JPanel so I can zoom in and out.
I have also attached a mouse listener so I can detect the mouse clicks for the rectangles. I also do a transformation on the point so I can be use it during clicks while the panel is zoomed.
All of this works fantastic. The only issue I am having is that when the JScrollPane scroll bars change, I cannot select any of the rectangles.
I will give a step by step reproduction to be used with the code:
1.) Upon loading you will see two rectangles. Click the far right one. You'll see a window appear. Good. Move it to the far right side.
2.) Zoom in with your mouse wheel (push it towards you) until you cannot zoom anymore (May have to get focus back on the panel). You should see three rectangles. Click on the newly shown rectangle. Another window, titled rect3 should appear. Close both windows.
3.) This is where things get alittle tricky. Sometimes it works as intended, other times it doesn't. But do something to this affect: Scroll to the right so that only the third rectangle is showing. Try to click on it. If a window does not appear - that is the problem. But if a window does appear, close it out and try to click on the 3rd rect again. Most times, it will not display another window for me. I have to zoom out one step and back in. Then the window will appear.
After playing around with it for awhile, I first thought it may be a focus issue...I've put some code in the internal window listeners so the JPanel/JScrollPane can grab the focus upon window closing, but it still does not work. So, either the AffineTransform and/or point conversion could be the problem with the scroll bars? It only happens when the scroll bar has been moved. What affect would this have on the AffineTransform and/or point conversion?
Any help would be great.

What I'm noticing is your zoomedAffineTransform is changing when you click to close the internal frame. This ends up being passed down the line, thus mucking up your clicks until you do something to reset it (like zoom in and out).
Clicking on the JInternalFrame appears to add a translate to the g2d transform. This translation is what's throwing everything off. So in the paintComponent where you set the zoomedAffineTransform, you can verify if the transform has a translation before storing the reference:
         if (g2d.getTransform().getTranslateX() == 0.0) {
            zoomedAffineTransform = g2d.getTransform();
         }Edited by: jboeing on Oct 2, 2009 8:23 AM

Table does not fit into JScrollPane...

Hello,
I created a JTable and want to put this table into a JScrollPane, because the table is larger than the screen-size. The problem is that I never get the horizontal ScrollBar displayed, and the columns of my table are pressed together.
Just try yourself, here's a piece of my source code:
JTable table = new JTable(100,100);
JScrollPane pane = new JScrollPane(table);
I tried different constructor-versions of the JScrollPane-object, but the result was always the same: very very small columns and no horizontal ScrollBar.
Who can tell me how to do so...? I'd be very pleased about any kind of
advision because this problem really drives me crazy...
Thanx, Findus

Hi,
The reason that the horizontal scrollbar is not appearing is because you have the columns as resizeable. By default the column are automatically resizeable. You have to switch off the resizing.
The code should be something like this (an example)
import javax.swing.JFrame;
import javax.swing.JTable;
import javax.swing.JScrollPane;
public class MyFrame extends JFrame {
private JTable table = null;
public MyFrame() {
try{
GUI();
catch(Exception ex) {
ex.printStackTrace();
private void GUI() throws Exception {
table = new JTable(100, 100);
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
this.getContentPane().add(new JScrollPane(table);
this.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
this.setSize(400, 400);
this.setVisible(true);
public static void main(String[] args) {
MyFrame app = new MyFrame();
I hope this helps

Redisplaying jFrame with updated components

I have an object A that instantiates object B.
My object name is B_Object.
I call B_Object.setVisible(true);
(This is basically a jframe with jpanel with empty jScrollPane)
Later on, I call B_Object.redisplay() which I want to add components into my jScrollPane and redisplay the jFrame with the new information in the jScrollPane. However, it doesn't display everything in my jScrollPane. It looks like it wants to, but doesn't.
Is this a thread problem? Or I can't just recreate a jFrame that I already have it visible?

When you add or remove a component from a Container, then you need to revalidate() the container so the Layout Manager can be invoked.

Zooming a plot in a JScrollPane

Hi,
I am stuck! I'd appreciate it if you can get me unstuck ...
Below a trimmed-down .java file with a "main" that shows my problem. I create a JFrame. In the contentPane of this JFrame I put a JScrollPane, and in that JScrollPane I put a JPanel. I then show() the JFrame and set the preferredSize of the JPanel equal to it's actual getSize(). This way the scrollbars are just not required. If the user makes the JFrame a little bit smaller with the mouse, then the scrollbars appear. Try it!
In the JPanel I plot an artificial profile in a white rectangle, i.e. a simple cross-plot. To convert from userspace to physical space I use a combination of 4 affineTransforms, all according to 'the book'. All works lovely.
Now I want to zoom by dragging a box in the plot. Note that I already have the code that shows the zoom-box! Once I let go of the mouse (mouseReleased) I want to zoom on that box, and that's where it goes wrong. With some jickerypoke I can actually do the zoom (not in the code below), but ... the scrollBars do not appear, and the whole idea of course if that they do appear, so that the user can scroll up/down sideways without having to change the scaling.
( In essence the question is this: if I plot outside of the (user) min/max (for instance change the line "line.lineTo((float)x, (float)y[i]);" to "line.lineTo((float)x[i], (float)(y[i]+500));"), why does the JScrollPane not decide to pop-up the scrollBars so that the user can scroll to the bit outside of the (user) min/max? )
I'd be grateful for some pointers as to how to fix this, as I am going around in circles.

Thanx and Regards

What is the context you're asking these questions in? Are these interview questions? Homework questions? Or is there some underlying business problem you're trying to solve?

Create Query to restrict the user to a single row.                     I don't understand the question. You may be trying to create a VPD policy for the table, but that is far from clear from the question.
Query to get the first inserted record FROM a table.                Probably not possible in general. Oracle doesn't track the date at which a row was inserted.
Concatenate a column value with multiple rows.                          Again, I don't understand the question.
Query to delete all the tables at once.                You'd need dynamic SQL. And a definition of "all tables"-- are you talking about all tables in a particular schema? All the tables in multiple schemas? Something else? Does "at once" imply that you want things to run in parallel? And does "delete" really mean delete (a DML operation)? truncate (a DDL operation)? or drop?
SQL Query for getting Orphan Records.You'd need a definition of "orphan record" and requirements for what the parent and child tables are. The normal approach to finding parent and child tables dynamically would leverage foreign key constraints, but that would generally preclude the presence of orphan records.

Deleting multiple records using ibatis framework

The code i am using is
String deleteArray[ ] = request.getParameterValues("sel");
String selected= " " ;
if(deleteArray ! = null){
for(int i = 0; i < deleteArray.length ; i++){
selected += deleteArray [ i ];
if( i < deleteArray.length - 1){
selected += "," ;
I am using sqlMapClient of ibatis for connecting to database
sqlMapClient.delete("deleteMultipleRecords",selected);
In my xml file i use
<delete id="deleteMultipleRecords" parameterClass="java.lang.String">
delete from ADDRESS where id in (#value#)
</delete>
When i execute the above code , the delete query is not executing.Can anyone help me out.

I dont think so u can delete multiple recods with a sing line of querey.
Why dont u use a for loop in DAO file and call the query with a single value ....

Multiple AD account in single domain for a single user

Hi,
Does OIM support multiple AD account in single domain for a single user?
Scenario 1 :- If the multiple accounts already exists in AD can I pull it from AD to OIM for single user.
Scenraio 2:- Does OIM allow creation of multiple account in AD for a single user, when requested from OIM?
Thanks,

yes. this is possible. OIM allow this.
obviously the recon rule would be employee number or anything other than ' sAmAccontName' for target recon
while provisioning make sure you are generating unique sAmAccountName and Common Name(if in same OU) for same user
If you maintain above no issue having multiple account for a sing user in single domain

Filling out available space in JScrollPane

Hello all,
Is there a way to inform a JScrollPane that it's viewport's component should fill out the entire area of the viewport? I have a scroll pane whose viewport is a JPanel with a BoxLayout. The contents of the JPanel will change size depending on certain events. However, the JPanel at first is not very wide (it's components have a preferred size of 100), so it does not fill out the width of the viewport and is also displayed in the center of the scroll pane. Is there a way to have the JPanel fill out the entire viewport, or at least have it displayed on the left (I have set both the JViewport and JPanel's alignmentX values to 0.0 but it's still in the center)?
Thank you all for your time.

It looks like you have an intermediate panel between the viewport and the JPanel with the BoxLayout. In other words, the view is not the BoxLayout JPanel, but the intermediate one. A newly constructed JPanel will have FlowLayout and position the component top centered as displayed in your picture.
I wasn't lying when I said the JPanel should be the same size as the viewport. That's the default behavior. Example,
import javax.swing.*;
public class Demo {
    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
    private static void createAndShowGUI() {
        try {
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        } catch (Exception e) {
            e.printStackTrace();
        String lines = "------------\n" +
                       "------------\n" +
                       "------------\n" +
                       "------------\n" +
                       "------------\n";
        JFrame frame = new JFrame();
        //Box musicPanel = Box.createVerticalBox();
        JPanel musicPanel = new JPanel();
        musicPanel.setBorder(BorderFactory.createEtchedBorder());
        musicPanel.setLayout(new BoxLayout(musicPanel,BoxLayout.PAGE_AXIS));
        Box tempo = Box.createHorizontalBox();
        tempo.add(new JLabel("Temp = 120"));
        tempo.add(new JButton("Change Tempo"));
        musicPanel.add(tempo);
        musicPanel.add(new JLabel("Tack 0: tuba"));
        musicPanel.add(new JTextArea(lines));
        musicPanel.add(new JLabel("Track 1: trombone"));
        musicPanel.add(new JTextArea(lines));
        musicPanel.add(new JLabel("Track 2: C_trumpet"));
        musicPanel.add(new JTextArea(lines));
        musicPanel.add(new JLabel("Track3: English_horn"));
        leftAlign(musicPanel);
        frame.setContentPane(new JScrollPane(musicPanel));
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    private static void leftAlign(JComponent parent) {
        parent.setAlignmentX(JComponent.LEFT_ALIGNMENT);
        for(java.awt.Component c : parent.getComponents()) {
            leftAlign((JComponent) c);
} If you change
frame.setContentPane(new JScrollPane(musicPanel)); to
JPanel intermediate = new JPanel();
intermediate.add(musicPanel);
frame.setContentPane(new JScrollPane(intermediate)); in the above code, then you'll get something that looks remarkably like the picture you provided.

SpringLayout problem for JScrollPane

hi,
Though i can add JScrollPane all my panels that i use layoutmanagers except
springlayout ; i cannot add JScrollPane to a panel that use springLayout as layout manager. if someone helps me , i will be very pleased. I need it for my graduation project so i'm in trouble with this problem:(
thanks

Putting in explicit constraints in a reverse direction (i.e. constraing the container's edges to the label) fixes the problem:
    public static void main(String[] argv)
        final SpringLayout layout = new SpringLayout();
        JPanel center = new JPanel(layout);
        final JLabel label = new JLabel("hello");
        label.setFont(label.getFont().deriveFont(150.0f));
        Spring heightSpring = Spring.height(label);
        Spring widthSpring = Spring.width(label);
        center.add(label);
//        layout.putConstraint(SpringLayout.NORTH, label, 0, SpringLayout.NORTH, center);
//        layout.putConstraint(SpringLayout.WEST, label, 0, SpringLayout.WEST, center);
//        layout.putConstraint(SpringLayout.EAST, label, widthSpring, SpringLayout.WEST, center);
//        layout.putConstraint(SpringLayout.SOUTH, label, heightSpring, SpringLayout.NORTH, center);
        layout.putConstraint(SpringLayout.NORTH, center, 0, SpringLayout.NORTH, label);
        layout.putConstraint(SpringLayout.WEST, center, 0, SpringLayout.WEST, label);
        layout.putConstraint(SpringLayout.EAST, center, widthSpring, SpringLayout.WEST, label);
        layout.putConstraint(SpringLayout.SOUTH, center, heightSpring, SpringLayout.NORTH, label);
        JScrollPane pane = new JScrollPane();
        pane.setViewportView(center);
        JFrame f = new JFrame();
        f.setContentPane(pane);
        f.setSize(100, 100);
        f.setVisible(true);
    }The commented-out lines make no difference to the behaviour wrt the scrollpane.
