X JPanels in a JTabbed pane.

I'm wondering if anyone can help.
I have an application consisting of a JTabbed pane, within this there should be 'x' JPanels. Each JPanel has 3 RadioButtons and 5 Text fields. I need to be able to refer to each radio button and text field as RB0 - RBx and TF0 - TFx.
It is obviously easy enough to do this for just 3 or even 20 (despite a lot of coding), however, my problem is getting a variable number (x) of Panels with respective variable numbers of TF and radio buttons.
Simply I need to produce an array of panels, radiobuttons and textfields....
anyone anyideas?

another way of looking at it is to think how can I make 5 of exactly the same panel (just with different names) in the same tabbed frame in just one bit of code that is called 5 times - or x in this case.

JTabbed pane customize title on selection

Hi all
i want to change the title font when a tab is selected.I add a ChangeListener to my JTabbed pane to intercept tab selection and to change font via html.
I have some proble ex:
if i click on tab4, it correctly change font but the tab2 take the title of the tab1 and so on.
This is the code
          ChangeListener changeListener = new ChangeListener()
               public void stateChanged(ChangeEvent changeEvent)
                    JTabbedPane sourceTabbedPane = (JTabbedPane) changeEvent.
                         getSource();
                    int index = sourceTabbedPane.getSelectedIndex();
                    for (int i = 0; i < sourceTabbedPane.getTabCount(); i++)
                         if (i == index)
                              sourceTabbedPane.setTitleAt(i,
                                   "<html><b>" + sourceTabbedPane.getTitleAt(i) + "</html>");
                         else
                              String desc = sourceTabbedPane.
                                   getTitleAt(i).replaceAll("<html>", "").
                                   replaceAll("<b>", "").replaceAll("</html>", "");
                              sourceTabbedPane.setTitleAt(i, desc);
                    System.out.println("***********************");

                         System.out.println(sourceTabbedPane.getTitleAt(i));
          };The last system.out show me the correct tirtle, only the selected with html but on screen i see some mixed title.Where i'm wrong?

2nd time posting: Flashing JTabbed Pane?

I'm trying to use a JTabbed Pane wherein tabs are created dynamically from the server. In order to alert the the user of the client software that a new tab has been created, I would like the top of the tab to flash or blink with a different color. any ideas how to do this? I really do want to avoid doing stuff like writing my own component etc.
Tia,
carlos

You can use:
tabPane.setBackgroundAt(i, Color.red);to set the background of tab number "i" to red, and
you can use:tabPane.setBackgroundAt(i, tabPane.getComponentAt(i).getBackground());to set the background of tab number "i" back to its original color. If you do these in a loop with a delay, then you have a flashing tab.
You can also change the font color if you want by using tabPane.setForeground(...) instead of setBackground(...)

Focus event with JTabbed pane

How do I set FocusListener to fire with I select a specific tab in a JTabbed pane? If I put the FocusListener on the Tabben pane it fires rquardless of which tab I select and if I try to use an if statement to single out a specific tab nothing happens.

If you are interested in listening to when a tab is selected you can use a ChangeListener:
JTabbedPane tab = ...
tab.addChangeListener(new ChangeListener() {
    public void stateChanged(ChangeEvent e) {
        // get the selected tab-index:
        int index = ((JTabbedPane)e.getSource()).getSelectedIndex();
});Btw, Swing related posts should be posted in the Swing forum.

Icon in the JTABBED PANE

hello...
How can I put an Icon into the JTABBED PANE?
So every TAB will have its own Icon?
I believe JBuilder 4.0 do that.
Thank you.

Read http://java.sun.com/docs/books/tutorial/uiswing/components/tabbedpane.html
tabbedPane.addTab("Title", image, panel, "Tooltip");

JCombobox on a jtabbed pane, AND Choice on jtabbed pane problems

I have a Choice on a jtabbed pane, on a panel that isn't showing when the jtabbed pane is made visible. The Choice on the hidden pane is "bleeding" through to the first tabbed panel. help!
If I click on the second tabbed panel (where the Choice is), and then click on the first tabbed panel, the Choice becomes hidden like it is supposed to.
AND, I have a JComboBox on a JTabbedPane, it works for the most part, but when you click on it, the scrollbox underneath it doesn't appear! Instead, a grey box appears below it. Help!

I was having similar problems when I was working with JFrames, Anything not covered by a piece of GUI would show other parts of my program (like the progress bar or buttons and stuff).
Anyway, it went away when I used the setBackground() method. My guess is that using this forces the container to be opaque or something. Anyway, it worked for me, maybe it will work for you also.

Transparent JTabbed Pane

Is there a way to make a JTabbed Pane transparent, include the tabs?

What do you mean? A JTabbedPane simply displays the currently selected component. In order for the whole thing to be transparent, the components contained in the JTabbedPane also need to be transparent.

Jtabbed pane is listening to the keyboard, how do i stop?

hello
this is probobly a simple Swing problem. i have a j3d canvas inside a tabbed pane with other info on other panes. i need the keyboard to listen on the canvas so i can move around the j3d world, but the left and right are being detected by the jtabbed pane, but i didnt add any listen to those. how can i stop this behavior from occuring? its very annoying.
i appreciate any help you can lend..

The reason it is responding to keyboard events is becuase it has the focus. Request focus on the component in the tab, and the tabbed pane should stop responding. If that doesn't work, try this:
JTabbedPane tabbed = new JTabbedPane();
KeyStroke[] keys = tabbed.getRegisteredKeyStrokes();
for (int i=0; i<keys.length; i++) {
int code = keys.getKeyCode();
if (code == KeyEvent.VK_LEFT || code == KeyEvent.VK_RIGHT) {
tabbed.unregisterKeyboardAction(keys[i]);

Jtabbed pane problem + flags printout

Hi,
I am having difficulty displaying a JTabbedPane which is contained by a dialog. When I display the Dialog for the first time the Tabbed displays perfectly - anytime after that it disappears.
I found this really strange so I put in some printout statements for the JTabbed pane here's what I got
When it displays the prinout for the JTabbed pane is ............................
extCellTabbedPane
rnh.adj.cellhandovermgt.gui.refactor.ExtCellTabbedPane[,0,0,0x0,invalid,layout=javax.swi
ng.plaf.basic.BasicTabbedPaneUI$TabbedPaneLayout,alignmentX=null,alignmentY=null
,border=,flags=0,maximumSize=,minimumSize=,preferredSize=,haveRegistered=false,t
abPlacement=TOP]
When it does n't display the prinout for the JTabbedPane is
rnh.adjcellhandovermgt.gui.refactor.ExtCellTabbedPane[,0,67,193x45,inv
alid,layout=javax.swing.plaf.basic.BasicTabbedPaneUI$TabbedPaneLayout,alignmentX
=null,alignmentY=null,border=,flags=16,maximumSize=,minimumSize=,preferredSize=,
haveRegistered=false,tabPlacement=TOP]
What I am interested in is the meaning of the parameter flags. In one case it is 0 and in one case it is 16? What does this parameter mean? Where I can get some information on this as I think this will tell me what is happening to the JTabbedPane.
Thank you in Advance
Alex

The flags item reflect the flags value in JComponent
class. It represents several status
of the component:
REQUEST_FOCUS_DISABLE
IS_DOUBLE_BUFFERED
ANCESTOR_USING_BUFFER
IS_PAINTING_TITLE
HAS_FOCUS
IS_OPAQUE
As my understand about your problem, this may be no
help for you to locate the error
As the message you post, you might use a third
implementation of JTabbedPane, so the
problem might be in the implementation. I
have used JTabbedPane often with no error
like you say :)
Hope this Helps!Thanks for your help here - I would like more information if possible i.e. a numerical mapping for each property - do you know where I could get this. I don't really understand what you mean about the Third implementation. Do you mean simply extend the JTabbedPane? Thisis what I do but I don't really know what part to change to stop it disappearing. Thanks once again. Anymore help would be greatly appreciated.

JTabbed pane row shifting

Hi,
I would like to ask one question - In a JTabbed pane which has WRAP_TAB_LAYOUT , the tabs will be shown in more than one rows when number of tabs is more -When I click a tab in upper row, that row will come down - Is there any way to override this default behaviorur - that is the tabs should reamai in same position when I click

If you force a particular L&F you can do this. For example, if you force the basic L&F you can create a subclass of BasicTabbedPaneUI which uses a subclass of BasicTabbedPaneUI.TabbedPaneLayout which overrides calculateTabRects.

Images with JTabbed Pane

the panels that i am using in JtabbedPane load images in background at run time when i seperately run them images are loaded but when the panels are used in tabed pane images are not visible

I have overriden the function . what i am using for my panels is the Image panel which is derived from panel class and i create an instance of that image panel on my panel that is to be added on jtabbed control but it is not showing

JTabbed Pane and Opaqueness ??????????????????

Hi All,
I have developed an application in Swing that uses JTabbedPane.The tabbed pane(say tabbedpane X),has a panel which is in turn made from 2 panels,say panel A and panel B.
I want to display the space beween the 2 panels,A and B by using the SetOpaque method.But this is not working.!!!!!!!!!!!!!!!!
Could any one explain or send me a sample code of "how to introduce opaqueness between 2 Panels originating from JTabbedPane "
Many Thanks,
Sabriz

You want to display the space between the two panels like showing the cellspaceing in HTML? Is that correkt?
Opaque isn't the right way to show this.. Opaque just turns on/off drawing the background of Components
Try this ...
          JFrame frame = new JFrame();
          frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          JPanel p = new JPanel(new GridLayout(2,2,10,10));
          p.setBackground(Color.BLACK);
          for(int i=0; i<4; i++) {
               JPanel tmp = new JPanel();
               tmp.setBorder(new LineBorder(Color.RED));
               tmp.setBackground(Color.GRAY);
               p.add(tmp);
          frame.setContentPane(p);
          frame.setSize(200, 200);
          frame.setVisible(true);Martin

Fitting JPanel perfectly inside content pane of JFrame

Say I have a JPanel with size W x H that I want to add to a JFrame such that the JFrame will be sized as small as possible while still fitting the panel inside its content pane. Is there a method in JPanel that I can overwrite or a specific method of adding to a JFrame that I can use to accomplish this, or do I need to calculate the JFrame's size with getInsets()?
Thanks.

If I do this...
JFrame frame = new JFrame("Pack Test");
JPanel panel = new JPanel();
panel.setSize(300, 300);
frame.add(panel);
frame.pack();
frame.setVisible(true);...the resulting content pane is most definitely not 300x300 pixels. What am I doing wrong?

Buggy JTabbed Pane, Scroll? Constraints?

I don't know if this is a bug, limitation, or if I'm not implementing it properly, but I am having a problem with scroll panes in a tabbed frame.
Here's the scoop.
I have a JFrame which has a has a JTabbedPane north and a JPanel (which contains a couple components) down south.
The tabbed pane has 4 tabs/panes. Only the first two are relevant right now because I haven't made it to the last two.
Tab 1 has a JPanel with a gridlayout (2 cols, 3 rows). The components display fine until I populate tab 2 with my 25 rows of stats. Once that happens, the JFrame (the container/content pane, not the physical window) size stretches itself to about 600px tall.
Tab 2 contains a JPanel with a gridlayout (2 cols, 25 rows). As described above, this many rows causes every pane in the tabbed pane set to take on this size, causing undesirable spacing. Not only that, you have to resize the window to display it all.
My solution was to use a JScrollPane to contain the JPanel with all the rows, and then add the JScrollPane to the tab. This just doesn't work. The result was just a border around the JPanel, no scroll.
Can someone give me some ideas on how to use a JScrollPane as the component in the tab 2?
Also, how do I control the size of JPanels in the the tabbed panes so they do not change based on the size of another pane?
Thanks So Much!!!
Here is my constructor code (irrelvant logic not included):
public CbStats() {
//create main frame
JFrame frame = new JFrame("VSN1 Callback Stats");
frame.setSize(400,200);
//main container
Container content = frame.getContentPane();
//tabbed pane goes north
JTabbedPane tabs = new JTabbedPane();
//flow panel goes south
JPanel southPanel = new JPanel();
southPanel.setLayout(new FlowLayout());
//add status and manual refresh
JLabel status = new JLabel("Refresh Rate: 2 mins ");
southPanel.add(status);
JButton manRefresh = new JButton("Manual Refresh");
southPanel.add(manRefresh);
//create 4 panels, 1 for each tab
JPanel panSummary = new JPanel();
JPanel panPerf = new JPanel();
JPanel panNotes = new JPanel();
JPanel panJump = new JPanel();
//add stuff to panel 1
panSummary.setLayout(new GridLayout(5,2));
panSummary.add(new JLabel(" Open Tickets:"));
panSummary.add(openTix);
panSummary.add(new JLabel(" Assigned Tickets:"));
panSummary.add(assignedTix);
panSummary.add(new JLabel(" Closed Tickets:"));
panSummary.add(closedTix);
//add stuff to panel 2
//panPerf.setLayout(new FlowLayout());
panUsers.setLayout(new GridLayout(25,4));
for(int i=0;i<ulAr.length;i++) {
ulAr[i] = new JLabel();
panUsers.add(ulAr);
panPerf.add(panUsers);
//add panels to tabs
tabs.add(panSummary, "Summary");
tabs.add(panPerf, "Performance");
tabs.add(panNotes, "Notes");
tabs.add(panJump, "Jump To...");
//add tabbed pane to main frame
content.add(tabs, BorderLayout.NORTH);
content.add(southPanel, BorderLayout.SOUTH);
//make visible
frame.setVisible(true);

You have to specify real panel's size.
panel.setPrefferedSize(...);
JScrollPane will ask the panel and if the size of panel is bigger than the size of scrollpane scrollbars appear.
And of course you have to specify size of scroll.
hope this helps.

JTabbed Pane ArrayIndexOutOfBoundsException

Not sure if this is a java bug or just an error in my code.
After focusing on the last tab (tab 5) and closing it (by pressing a key)
then clicking on the new last tab (tab 4)
-> an ArrayIndexOutOfBoundsException occurs.
The code:
import java.awt.event.*;
import javax.swing.*;
public class Test extends JFrame implements KeyListener{
private JTabbedPane tab;
public Test(){
this.setSize(400,400);
tab = new JTabbedPane();
this.getContentPane().add(tab);
for (int x=0;x<6;x++)
tab.add(""+x,new JPanel());
tab.addKeyListener(this);
this.setVisible(true);
public void keyPressed(KeyEvent e) {}
public void keyReleased(KeyEvent e) {}
public void keyTyped(KeyEvent e) {
tab.removeTabAt(tab.getSelectedIndex());
public static void main(String[] args){
new Test();

I am using 1.5.0 beta 2. Any thoughts?

The exception is thrown when clicking on the last tab after the first removal (trying to select it) not when trying to remove it. And looking at java's source, the selection is changed when a tab is removed.
