Eclipse Tab and CButton

CButton a= new CButton("test1",null);
CButton b= new CButton("test1",null);


if icon is null,Eclipse Tab still has button,blank button.
But I look forward to no buttons appear,I just want to right-click Eclipse Tab then popup menu.
I think my expectations are reasonable.

Sorry, my English is very bad.

Well, changing the behavior because of whether there is an icon or not sounds very counterintuitive for me. Also if a user uses only the keyboard he cannot trigger actions that do not show up on a title/tab.

But of course there is a little hack that you can use. Overriding the “createView” method as in the example below allows you to hide a CButton. For the other CActions similar code can be written (just ask if you need them as well).

import javax.swing.Icon;
import javax.swing.JFrame;

import bibliothek.gui.Dockable;
import bibliothek.gui.dock.action.view.ActionViewConverter;
import bibliothek.gui.dock.action.view.ViewTarget;
import bibliothek.gui.dock.common.CControl;
import bibliothek.gui.dock.common.DefaultSingleCDockable;
import bibliothek.gui.dock.common.action.CButton;
import bibliothek.gui.dock.common.action.core.CommonSimpleButtonAction;

public class Dock02 {
	public static void main( String[] args ) {
		JFrame frame = new JFrame();
		frame.setBounds( 20, 20, 400, 400 );
		frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
		CControl control = new CControl( frame );
		DefaultSingleCDockable dockable = new DefaultSingleCDockable("a", "A");
		control.addDockable( dockable );
		dockable.setVisible( true );
		dockable.addAction( new MenuOnlyButton( "Action 1", null ));
		dockable.addAction( new MenuOnlyButton( "Action 2", null ));
		dockable.addAction( new MenuOnlyButton( "Action 3", null ));
		dockable.addAction( new MenuOnlyButton( "Action 4", null ));
		frame.setVisible( true );
	public static class MenuOnlyButton extends CButton{
		public MenuOnlyButton( String text, Icon icon ){
			super( text, icon );
		protected void init(CommonSimpleButtonAction action) {
			// we completely ignore "action" and use a custom DockAction that does
			// not show up on a title
			CommonSimpleButtonAction replacement = new CommonSimpleButtonAction(this){
				public <V> V createView(ViewTarget<V> target, ActionViewConverter converter, Dockable dockable) {
					if( target == ViewTarget.TITLE ){
						return null;
					return super.createView(target, converter, dockable);
			super.init( replacement );

Thank you.
MenuOnlyButton is what I need.
