All actions on tabs (this will get you extra actions, not only mouse clicks, for example, if you change tab by code using selected index, this code will be executed):

ChangeListener changeListener = new ChangeListener() {
  public void stateChanged(ChangeEvent changeEvent) {
    JTabbedPane sourceTabbedPane = (JTabbedPane) changeEvent.getSource();
    int index = sourceTabbedPane.getSelectedIndex();
    System.out.println("Tab changed to: " + sourceTabbedPane.getTitleAt(index));
  }
};
myJTabbedPanel.addChangeListener(changeListener);

Only mouse clicks on tabs:

/** 
 * Detects clicks when user click tab inside tabbed pane 
 */ 
private void addMouseEventToPanel(){ 
  this.myJTabbedPanel.addMouseListener(new MouseListener() 
  { 

    @Override 
    public void mouseClicked(MouseEvent e) { 
      // TODO Auto-generated method stub 
      System.out.println("You clicked on tab number "+this.myJTabbedPanel.getSelectedIndex()); 
    } 

    @Override 
    public void mousePressed(MouseEvent e) { 
      // TODO Auto-generated method stub 

    } 

    @Override 
    public void mouseReleased(MouseEvent e) { 
      // TODO Auto-generated method stub 

    } 

    @Override 
    public void mouseEntered(MouseEvent e) { 
      // TODO Auto-generated method stub 

    } 

    @Override 
    public void mouseExited(MouseEvent e) { 
      // TODO Auto-generated method stub 

    } 

  });
}

I assume you mean when a user clicks on an existing tab to switch to that tab. If so, then you can add a ChangeListener to the tabbedPane and listen for the stateChanged event.

If you are talking about adding a new tab to the tabbed pane, then you would just manage that in your application logic.
