Question on JTabbed Pane
Hi, I am working on a swing application, which uses JTabbedPane. I am stuck at one point.
There are two tabs and when the button in first tab is clicked, the second tab should show up (User should be able to see the components in another tab). How can I achieve that? Do I need to implement the ChaneListener or setting the focus to another tab would work? Please give me a hint or example.
Thank you,
Jyothi
Read the JTabbedPane API. You find a set... method that allows you to select a different tab.

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

anikutsIf 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.

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.

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,
carlosYou 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(...) -
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. -
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.

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.

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
AlexThe 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 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("***********************");
for (int i = 0; i < sourceTabbedPane.getTabCount(); i++)
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?I hope can you help me:
public static void main(String[] arg)
JTabbedPane jTabbedPane = new JTabbedPane();
jTabbedPane.addTab("Tab1", new JPanel());
jTabbedPane.addTab("Tab2", new JPanel());
jTabbedPane.addTab("Tab3", new JPanel());
jTabbedPane.addTab("Tab4", new JPanel());
jTabbedPane.addTab("Tab5", new JPanel());
jTabbedPane.addTab("Tab6", new JPanel());
jTabbedPane.addTab("Tab7", new JPanel());
jTabbedPane.addTab("Tab8", new JPanel());

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("***********************");
for (int i = 0; i < sourceTabbedPane.getTabCount(); i++)
System.out.println(sourceTabbedPane.getTitleAt(i));
jTabbedPane.addChangeListener(changeListener);
JDialog dialog = new JDialog(new JFrame(),true);
dialog.getContentPane().add(jTabbedPane);
dialog.setPreferredSize(new Dimension(300,300));
dialog.setSize(new Dimension(300,300));

Firefox style jtabbed pane questions
hey
i am wondering if it is possible to create in java tabbed pane that can be closed independentaly
for example firefox tabs, they can be closed by an X button on the rightI'm having trouble with the JTabbedPane too. I cut and pasted this right from the Sun tutorial on the JTabbedPane, but when I try to run it under Eclipse, it won't compile. It gives me
1) Syntax error on token(s); misplaced construct(s)
2) Syntax error on token ItemPanel, VariableDeclaratorId expected after this token
3) Syntax error on token "Items"; invalid FormalParameterList
<code>
import javax.swing.*;
import javax.swing.SwingConstants;
public class TabContainer
JTabbedPane tabbedPane = new JTabbedPane();
ItemDataPanel itemPanel = new ItemDataPanel();
tabbedPane.add("Items", itemPanel);
</code>
This is EXACTLY what the tutorial says to do. Every other source says the same thing. What is wrong with it? -
i have a jframe with mutltiple tabs...
in each tab thee is a panel that have different components(text fields....) my question is lets say i write something in a textfield and change the tab and get back to that tab, how can i make it when this tab opened reset all fields???
how can i also make it when a tab is opened , it call a certain method ???
thanks in advanceAdd a focus listener to the component that you've placed in the tab. Then choose to clear all the fields either:
1. When you're leaving the tab:
-call your own custom "clear all fields" method inside focusLost()
2. When you're coming back to the tab:
-call your own custom "clear all fields" method inside focusGained()
Either of these should be acceptable... But if there's no reason to hold onto the information once they leave the tab... then I would clear the text when you were coming back... because then if they DON'T come back, the code to clear wont run and you'll be using less cycles.
On the other hand, if you ever notice your fields "clearing" while coming back to the tab, then switch over to the other way.
Good luck :-)
