How to repaint a DefaultSingleCDockable tab-title

I have an application that shows content in several DefaultSingleCDockable tabs.

Sometimes this cotents are GLJPanel based, and they have an issue that makes other components disappear in a specific situation. On this cases, I have to rapaint() part of the interface. The only thing I still can’t get repainted is the Tab-Title.

I’m looking for something like “dockable.repaint()”, or “dockable.getTitleTab().repaint()”.

Changing the text with dockable.setTitleText(…) does the trick, IF I really change the text to something else, but I need to keep the same text. If I do dockable.setTitleText(dockable.getTitleText()), It does not repaint.

Any tip?

Interesting issue you have.

For most themes you can iterate through the “representatives” of a Dockable to find the Component that paints the tab. Like in the example below.

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JFrame;

import bibliothek.gui.dock.DockElementRepresentative;
import bibliothek.gui.dock.common.CControl;
import bibliothek.gui.dock.common.CGrid;
import bibliothek.gui.dock.common.DefaultSingleCDockable;
import bibliothek.gui.dock.common.SingleCDockable;
import bibliothek.gui.dock.common.action.CButton;
import bibliothek.gui.dock.common.intern.CDockable;
import bibliothek.gui.dock.common.theme.ThemeMap;

public class RepaintExample {
	public static void main( String[] args ) {
		JFrame frame = new JFrame( "Test" );
		CControl control = new CControl( frame );

		control.setTheme( ThemeMap.KEY_ECLIPSE_THEME );
		frame.add( control.getContentArea() );

		CGrid grid = new CGrid( control );
		grid.add( 0, 0, 1, 1, dockable( control, "a", "Aaaa" ) );
		grid.add( 0, 0, 1, 1, dockable( control, "b", "Bbbb" ) );
		control.getContentArea().deploy( grid );

		frame.setBounds( 50, 50, 800, 800 );
		frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
		frame.setVisible( true );
	private static SingleCDockable dockable( CControl control, String id, String title ){
		DefaultSingleCDockable dockable = new DefaultSingleCDockable( id, title );
		CButton button = new CButton();
		button.setText( "Repaint" );
		button.setShowTextOnButtons( true );
		button.addActionListener( new RepaintAction( control, dockable ) );
		dockable.addAction( button );
		return dockable;
	private static class RepaintAction implements ActionListener{
		private CControl control;
		private CDockable dockable;
		public RepaintAction( CControl control, CDockable dockable ){
			this.control = control;
			this.dockable = dockable;
		public void actionPerformed( ActionEvent e ) {
			DockElementRepresentative[] representatives = control.getController().getRepresentatives( dockable.intern() );
			for( DockElementRepresentative view : representatives ){
				System.out.println( String.format( "repainting %s: %s", view.getClass().getSimpleName(), view.toString() ));

The default theme uses a JTabbedPane, and the tabs there are not that easy to access. Perhaps repainting the JTabbedPane might help, like this:

		public void actionPerformed( ActionEvent e ) {
			JTabbedPane tabbed = (JTabbedPane) SwingUtilities.getAncestorOfClass( JTabbedPane.class, dockable.intern().getComponent() );
			if( tabbed != null ) {
				for( int i = 0, n = tabbed.getTabCount(); i < n; i++ ) {
					Rectangle tabBounds = tabbed.getBoundsAt( i );
					if( tabBounds != null ) {
						System.out.println( String.format( "repainting %d, %s", i, tabBounds ) );
						tabbed.repaint( tabBounds );
