如何防止通过鼠标单击更改选项卡

Question

my question could be silly but I'm trying to disable changing of tabs by mouse click in JTabbedPane . I searched on google but didn't found any helpful answer. I tried to add empty MouseListener but still I can change the tab on mouse click.

My Code is as follows:

public JTabbedPane createTabbedPane()
{
    JTabbedPane pane=new JTabbedPane();
    pane.addTab("tab1",panel1);
    pane.addTab("tab2",panel2);
    pane.addTab("tab3",panel3);
    pane.addMouseListener(new MouseAdapter());
    return pane;
}

I also tried this one:

public JTabbedPane createTabbedPane()
{
    JTabbedPane pane=new JTabbedPane();
    pane.addTab("tab1",panel1);
    pane.addTab("tab2",panel2);
    pane.addTab("tab3",panel3);
    pane.addMouseListener(new MouseListener()
    {
        @Override
            public void mouseClicked(MouseEvent e) {}

            @Override
            public void mousePressed(MouseEvent e) {}

            @Override
            public void mouseReleased(MouseEvent e) {}

            @Override
            public void mouseEntered(MouseEvent e) {}

            @Override
            public void mouseExited(MouseEvent e) {}
    });
    return pane;
}

If any one have any idea about how to do this please tell me. Thanks in advance.

Answer 1

You can block changing tabs by mouse with help of ChangeListener like next:

final JTabbedPane pane = new JTabbedPane();
pane.addChangeListener(new ChangeListener() {

    @Override
    public void stateChanged(ChangeEvent e) {
        pane.setSelectedIndex(HOLD_INDEX);
    }
});

HOLD_INDEX is index of tab selected programatically.

Here when you try to select another tab it will be reselected to HOLD_INDEX .

Answer 2

There are several things you could try...

You Could

Set the tabs you don't want selected to disabled...

pane.setEnabled(indexOfTab, false);

You Could

Supply your own SingleSelectionModel from which you can control which tabs can be selected

Answer 3

Another possibility could be to override the addMouseListener(...) with an empty implementation to prevent any mouse interaction. Sample code could be as follows:

JTabbedPane tabbedPane = new JTabbedPane() {
    public synchronized void addMouseListener(MouseListener l) { };
};
