How to switch tabs in jTabbedPane by clicking a Button?

Question

I have two JTabbedPanes, JTabbedPane1 & 2 How can I press button in JTabbedPane2 to show JTabbedPane1 ?

Here is the code for JTabbedPane:

public class TabbedPane extends JFrame {      public TabbedPane() {           setTitle("Tabbed Pane");           setSize(300,300);           JTabbedPane jtp = new JTabbedPane();         getContentPane().add(jtp);         JPanel1 jp1 = new JPanel1();//This will create the first tab         JPanel jp2 = new JPanel2();//This will create the second tab         //add panel .........      //example usage      public static void main (String []args){         TabbedPane tab = new TabbedPane();     }  } 

here is class JPane1:

...    JLabel label1 = new JLabel();        label1.setText("This is Tab 1");        jp1.add(label1); 

and class Jpane2 with button on int

JButton test = new JButton("Press"); jp2.add(test);

ButtonHandler phandler = new ButtonHandler(); test.addActionListener(phandler); setVisible(true);  

} so problem is here in ActionListener of button on Jpanel2

class ButtonHandler implements ActionListener{        public void actionPerformed(ActionEvent e){               // what i do now ? to call  jpanel 1 show ![alt text][1]        } } 

Answer 1

If you make the tabbed pane accessible to ButtonHandler you can do this:

class ButtonHandler implements ActionListener{        public void actionPerformed(ActionEvent e){               jtp.setSelectedIndex(0);        } } 

You can do this by making jtp (ideally with a better name) a private attribute with a getter method or it can be passed in as a constructor argument to ButtonHandler.

Answer 2

You should use the method JTabbedPane.setSelectedIndex(int index) with the index of the tab you want.
