Question

I am using my predefined inherited Focus Traversal Class For My JFrame

I have defined the key press event for one of my button with some action on pressing Tab key to select other tab of my jTabbed Pane . This button is not responding only for the tab key .

   int index=1;


    if(evt.getKeyCode() == KeyEvent.VK_TAB) 
      {

          // wrap around

    if(evt.isShiftDown())
    {

      KeyboardFocusManager.getCurrentKeyboardFocusManager().focusPreviousComponent();

    }   
    else
    {
     System.out.print("Shift Up");

      KeyboardFocusManager.getCurrentKeyboardFocusManager().focusNextComponent();
      jtabPaneProducts.setSelectedIndex(index);
    }
    }

Please guide me how can i made jbutton to respond to the TAB key press in addition to focus traversal functionality.
