Overriding Ctrl + Tab of JTabbedPane

Dear All ,
I have registered a keyboard action (ctrl+Tab key) to the
JTabbedPane instance in my program for " Shifting TabbedPane's Tabs " . But its not working. If i register with ( Ctrl + any other key )     it working fine.
     MY CODE:
     sm_tabpaneGUI.registerKeyboardAction(rightAction,KeyStroke.getKeyStrokejava.awt.event.KeyEvent.VK_TAB,java.awt.Event.CTRL_MASK),JComponent.WHEN_FOCUSED);
     where rightAction is an ActionListener object reference which does the necessary functionality.
But Acc. Bug Id 4481587 they have given a workaround.
" Edit the awt.properties files which have the focus traversal keys defined. "
It is not working. So any other workaround would be appreciated."

try dropping this into your app ..
DefaultFocusManager myManager = new DefaultFocusManager(){
     public void processKeyEvent(Component focusedComponent, KeyEvent anEvent)
     // Returning when you receive CTRL-TAB makes your components able to control that key
     if (anEvent.getKeyCode() == KeyEvent.VK_TAB && (anEvent.getModifiers() & KeyEvent.CTRL_MASK) == KeyEvent.CTRL_MASK)
          return;
     super.processKeyEvent(focusedComponent,anEvent);
FocusManager.setCurrentManager(myManager);

Overriding Ctrl+Tab

I try to override the Ctrl-Tab key combination using the following:
        final KeyStroke focusUnderneathTableKeyStroke = KeyStroke.getKeyStroke(KeyEvent.VK_TAB, Event.CTRL_MASK);
        wrapper.overrideShortcutKey(new FocusOnTableAction(false), focusUnderneathTableKeyStroke, "focusUnderneathTable");The method overrideShortcutKey() is:
    public void overrideShortcutKey( AbstractAction action, KeyStroke keyStroke, String sName )
        InputMap im = getComponent().getInputMap( JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT );
        ActionMap am = getComponent().getActionMap();
        im.put( keyStroke, sName );
        am.put( sName, action );
    }This does not seem to work. If, however, I replace the Tab key with 'Q', it works. I want this to transfer focus to a wrapper underneath a table.
Anybody any suggestions for this? And why does Ctrl+Tab not work whereas Ctrl+Q works?

I'm assuming by normal tab, you want to insert a tab. So here's this:
import java.awt.*;
import java.util.HashSet;
import java.util.Set;
import javax.swing.*;
public class TextAreaTab {
     public static void main( final String[] args ) {
          Runnable doCreate = new Runnable() {
               public void run() {
                    new TextAreaTab().createGUI();
          SwingUtilities.invokeLater( doCreate );
     private void createGUI() {
          JButton button = new JButton( "Button" );
          JTextArea textArea = new JTextArea();
          textArea.setText( "TextArea" );
          KeyStroke ctrlTab = KeyStroke.getKeyStroke("ctrl TAB" );
          Set set = new HashSet( textArea.getFocusTraversalKeys( KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS) );
          set.remove( ctrlTab );
          textArea.setFocusTraversalKeys( KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, set );
          textArea.getInputMap().put( ctrlTab , "insert-tab" );
          JFrame frame = new JFrame( "TextAreaTab" );
          frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
          frame.getContentPane().setLayout( new BorderLayout() );
          frame.getContentPane().add( button, BorderLayout.SOUTH );
          frame.getContentPane().add( textArea, BorderLayout.CENTER );
          frame.setSize( new Dimension( 250, 100 ) );
          frame.show();
}

Override "crtl + tab" key behaviour with "tab" key for JtextArea .

I am trying to override the "crtl + tab" key behaviour for JTextArea with "tab" key plus add my own action. I am doing the following.
1. Setting Tab as forward traversal key for the JTextArea (the default traversal key from JTexArea is "crtl + Tab").
2. Supplementing the "crtl + Tab" key behaviour with my custom behaviour.
For the point 2 above, I need to get hold of the Action represented by the "crtl + Tab" key so that I could use that and then follow with my own custom action. But the problem is that there is no InputMap entry for "crtl + tab". I dont know how the "crtl + tab" key Action is mapped for JTextArea. I used the following code to search the InputMap.
            System.out.println("Searching Input Map");
            for (int i = 0; i < 3; i++) {
                InputMap iMap = comp.getInputMap(i);
                if (iMap != null) {
                    KeyStroke [] ks = iMap.allKeys();
                    if (ks != null) {
                        for (int j = 0;j < ks.length ;j++) {
                            System.out.println("Key Stroke: " + ks[j]);
            System.out.println("Searching Parent Input Map");
            for (int i = 0; i < 3; i++) {
                InputMap iMap = comp.getInputMap(i).getParent();
                if (iMap != null) {
                    KeyStroke [] ks = iMap.allKeys();
                    if (ks != null) {
                        for (int j = 0;j < ks.length ;j++) {
                            System.out.println("Key Stroke: " + ks[j]);
            }In short, I need to get the Action associated with the "crtl + tab" for JTextArea.
regards,
nirvan.

There is no Action for Ctrl+TAB. Its a focus traversal key.

Vim Ctrl + Tab for Tabs navigation

:noremap <silent> <c-Tab> :tabn<CR>
noremap! <silent> <C-Tab> :tabn<CR>
This doesn't work for me - any idea why? Ctrl-tab just doesn't shift tabs... I've definitely not bound the combination elsewhere in my .vimrc either.

Regarding ctrl-tab and ctrl-shift-tab

hi,
i have a JFrame inside which i have a JInternalFrame and this contains 4 JPanels
which have components now,
when i press ctrl-tab from first panel's component the focus should move to
first component of next panel same from other panels and ctrl-shift-tab - reverse
how can i achive it ?
i extended FocusManager and by overriding processKeyEvent() i was able achieve what a wanted
but i have many JInternalFrames which are entirely diffenent from each other
so had to have different FocusManagers .
after setting new focusmanager the Mnemonic of JFrame were not working .
so i need any work arounds for the above problem.
desperately need help.
thanks.

Hi,
It should work. In the case, don't minimize the Book3.xlsx's window. Then you should be able to use Ctrl+Tab and Ctrl+F6 to switch between the book1,2 and 3.
Because Excel 2013 move to a single document interface, so there is no workbook title bar minimize, maximize, and close buttons. When you minimize the Book3's window in Excel 2013, the action will be treated as you have used the workbook title
bar minimize button to minimize the workbook.
In Excel 2010, the buttons can be found here:
If you use the workbook title bar minimize button in Excel 2010 instance, the same behavior can be reproduced.

Ctrl+tab is not working in editing mode

I have JcheckBox and JTable in my JPanel. When user clicks or presses F2 to edit any cell value of the JTable a comboBox will appear with possible values. (This comboBox is coming from table CellEditor). When user presses ctrl+tab from the table focus should transfer to JComboBox all time. It is working only when the user presses ctrl+tab from the table cell which is not in editing mode. If the user presses ctrl+tab from the table cell which is in editing mode (i.e. focus is on the ComboBox of the cellEditor) it does not work. Please help me to find the solution.
I give a sample code here for your reference.
public class Frame1 extends JFrame {
public Frame1()
super();
this.setLayout( null );
this.setSize( new Dimension(400, 300) );
JTextField ch = new JTextField();
ch.setVisible(true);
ch.setBounds(10, 10, 10, 10);
this.add(ch, null);
DefaultTableModel tmodel = new DefaultTableModel(3, 1);
tmodel.setValueAt("0 0 1",0,0);
tmodel.setValueAt("1 0 1",1,0);
tmodel.setValueAt("2 0 1",2,0);
JTable custLayersTable = new JTable(tmodel);
custLayersTable.getColumnModel().getColumn(0).
setCellEditor(new ComboEditor());
custLayersTable.setBounds(new Rectangle(40, 40, 280, 145));
custLayersTable.setSurrendersFocusOnKeystroke(true);
this.add(custLayersTable, null);
public static void main(String[] args)
Frame1 a = new Frame1();
a.setVisible(true);
final class ComboEditor extends AbstractCellEditor
implements TableCellEditor
public Component getTableCellEditorComponent(JTable table,
Object value,
boolean isSelected,
int row,
int column)
Vector<String> layerValSet = new Vector<String>();
for(int i=0; i<3; i++)
layerValSet.add(row+" "+column+" "+i);
mComboModel = new DefaultComboBoxModel(layerValSet);
mComboModel.setSelectedItem(value);
mEditorComp = new JComboBox(mComboModel);
return mEditorComp;
public Object getCellEditorValue()
return mEditorComp.getSelectedItem();
private DefaultComboBoxModel mComboModel;
private JComboBox mEditorComp;
}

Thanks a lot for your reply.
Since the textField is in a different class i could not use the transferFocus API directly. I tried the following code in the keyreleased event of Combo Box but it was not working.
KeyboardFocusManager.getCurrentKeyboardFocusManager().focusNextComponent(
e.getComponent().getParent());
I also tried the following code in stopCellEditing and is not working.
KeyboardFocusManager.getCurrentKeyboardFocusManager().focusNextComponent();
Is there any other way to achieve this?

My PC is W81, and I'm RDing into a W7 machine running Visual Studio 2013 SP4.
When I press Ctrl+Tab (and hold), I very briefly see the usual editor window list come up, but it goes away and the editor does not switch.
If I hold Ctrl+Tab and let the repeat start, the same thing happens in rapid succession, but the current tab still never changes.
I have of course rebooted both client and server, and made sure my keyboard wasn't at fault and toggled all the keys. No dice.
Thanks.

Sorry, but that doesn't get me the original behavior, where I can tab through the list or double-tab, triple-tap TAB to visit the last, second to last, or third to last file I visited (or I could use the visual navigator). I frequently use these commands,
and it's really slowing me down.
Can I please get an admission this is a bug and a commitment to fix it?

Ctrl+Tab and Ctrl+F6 still not working in Excel 2013?

I am using Windows 7 64-bit. I just switched to Office Home & Business 2013 (32-bit), and I discovered that ctrl+tab behavior in Excel 2013 is incredibly broken.
If you are using any other programs concurrently with Excel, then it makes switching tasks through ctrl+tab impossible. Switching workbooks in this way has unpredictable behavior: often, Excel will switch to a workbook that is hidden behind other windows
(fails to foreground the window correctly). Even when it appears to be switching appropriately between windows, the order of switching is wrong: rather than cycling through all windows, it seems to switch between workbooks somewhat randomly.

There does not appear to be any solution to this issue so far. I have attempted to repair my installation of Microsoft Office, but it did not correct the problem.

Hi Dlup12345,
Based on my testes with local environment (Windows 8.1 and Excel 2013:15.0.4675.1000), the two Keyboard shortcuts worked as expected. In my view, this issue might be occur with Keyboard shortcuts, because you said the issue occurred intermittently. If we
only open multiple Excel files without other program, the shortcuts should worked fine. Please check if other program affected Excel shortcuts.
If you have any update, please feel free let us know.

I deleted the sign-in tab in Ctrl-Tab 0.21.1. How do I get it back?

I installed Ctrl-tab 0.21.1. Initially there were several tabs prefilled, one of which, was for sign-in. I made a mistake and deleted it and now I want to recover it. How do I do this? Thank you. Marsh

I tried installing several times and it did not work. Each time I downloaded it, and restarted the computer it went back to the web site you gave to down load. Each time I checked the Ctrl-Tab and the sign-in was not listed. Now I have done some further checking in the profile and it shows a blue dot in default, but none in on or off. I don't know if that makes a difference. In fact, when I down loaded it there was no difference between what I had and after the down load. In other words, what tabs I had when I first installed the Ctrl-tab did not appear, only the ones that I added, minus the sign-in tab, which I inadvertently deleted. I did remove Ctrl-tab before doing all this. Another thing I noticed is after restarting the computer it goes back to down load, but I do not get any indication that it is being installed. I hope this helps. Bruson

CTRL-Tab isn't working anymore in Indesign CC nor in CC (2014)

Hi, I use to switch between open documents using the CTRL-TAB and CTRL-SHIFT-TAB in Indesign.
Since we have upgraded to CC and now CC (2014) it seems that Indesign refuses to use these shortcuts.
All tough it's possible to assign them, they just do nothing.
I can assign also other shortcuts for this function and they do work, except the one I want.
While in Photoshop this works fine, in Illustrator it is not possible to assign such shortcut (that is another story).
What have I done? Removed prefs and even uninstalled and reinstalled all CC apps…
Any suggestions?

@Peter – yes.
It would be slightly different with a German keyboard layout on Mac OSX.
There it is:
cmd + <
and:
cmd + shift + <
Where the < key is right to the shift key on my MacBook Pro keyboard.
Or directly above the ctrl key, if that helps.

Version 33, problems when moving tab to new window, then if you open a new tab in that window it doesn't switch to it unless you use Ctrl-Tab?

Version 33, problems when moving tab to new window, then if you open a new tab in that window it doesn't switch to it unless you use Ctrl-Tab.

Type '''about:preferences'''<enter> in the address bar.
Select '''General.''' Look for '''Tabs.'''
Turn on '''When I open a link in a new tab, switch to it immediately'''

When I am on a Youtube video that is running and I want to switch to another tab, the Ctrl+ tab number does not work, is that intended functionality?

When I am on a Youtube video that is running and I want to switch to another tab, the Ctrl+<tab number> does not work, is that intended functionality?

This can happen when the video player (Flash plugin) has the focus.
In that case the plugin consumes all the key presses.
You will have to click with the mouse elsewhere on the page or in the user interface to make keyboard shortcuts work.

Changing Colors of selected tab in JTabbedPane.

Do someone has some code that can show how to
change the color of the selected tab with JTabbedPane.
I can change the other tabs colors with setBackground and setForeground, setBackgroundAt........ but it is the selected
tab that will not change from the default grey color.
thanks

try this code, it works.
public class TabBackgroundChange extends JFrame {
private JTabbedPane tabPane = null;
public static final Color selTabColor = Color.red;
Color nonSelectedTabColor = null;
public TabBackgroundChange() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
catch(Exception ex) {
ex.printStackTrace();
tabPane = new JTabbedPane();
tabPane.add("One", new JPanel());
tabPane.add("Two", new JPanel());
tabPane.add("Three", new JPanel());
this.getContentPane().add(tabPane);
this.setSize(200, 200);
this.setVisible(true);
tabPane.addChangeListener(new TabChangeListener());
tabPane.setSelectedIndex(1);
tabPane.setSelectedIndex(0);
public static void main(String[] args) {
TabBackgroundChange tabBackgroundChange1 = new TabBackgroundChange();
private class TabChangeListener implements ChangeListener {
public void stateChanged(ChangeEvent ce) {
int iSelTab = tabPane.getSelectedIndex();
Color unSelectedBackground = tabPane.getBackgroundAt(iSelTab);
for(int i=0; i<tabPane.getTabCount(); i++) {
tabPane.setBackgroundAt(i, unSelectedBackground);
tabPane.setBackgroundAt(iSelTab, Color.red);
}

Why Ctrl+Tab stops working when opening a flash embedded page?

This a huge pet peeve I have. Everytime I watch a video in youtube.com or megavideo.com, I can't just Ctrl+Tab to change tabs. I'll have to clic in some portion of the page without video to get it to work, but even that, isn't always the case.

Closable Tab in JTabbedPane

Hi
I trying to develop a Closable Tab in JTabbedPane. The close button should appear after/before the tab title all the time (like in JBuilder IDE).
I know the trick where close button appears when the mouse is in that area, but i want it to be displayed all the time irrespective of the mouse position.
How i should be able to create this component??
I am very new to swing please help...
Thanks for your help...

Thanks Stas,
Your code was really helpfull.
I've improved it a litte bit. So I'd like to share It.
To use it, just create a ClosableTabbedPane.
If you need to change the default action (remove the tab) then use the method setCloseTabAction(CloseTabAction) to change the action.
Cheers,
Rafa
