I am trying to create a JTabbedPane with tabs arranged vertically LEFT with SCROLL_TAB_LAYOUT. The code snippet for this is as below: 


private Component createTabbedPane() 
{
 JTabbedPane tabbedPane = new JTabbedPane(JTabbedPane.LEFT,
  JTabbedPane.SCROLL_TAB_LAYOUT);
 for (int i = 0; i < 20; i++) {
  JPanel pane = new JPanel();
  pane.add(new JLabel("This is Panel " + i));
  tabbedPane.addTab("Tab " + i, pane);
 }
 return tabbedPane;
}

However, I want have the same scrolling feature with mouse dragged so that it could be used for touch screen. Is there any way to use mouse listeners on the tabs?

    This would be helpful to you. Have a look at http://stackoverflow.com/questions/60269/how-to-implement-draggable-tab-using-java-swing and http://java-swing-tips.blogspot.com/2008/04/drag-and-drop-tabs-in-jtabbedpane.html. Fist link is simpler. – Ravindra Gullapalli Jan 25 '12 at 05:11

You can add mouseListners to the tabs themselves or to the tab components.

  • I tried by overriding the processMouseEvent and processMouseMotionEvent method for mouse drag. It works fine for a jtable, but not working for jtabbedpane. Which method should I need to modify to get this dragging behavior? – george b Dec 09 '10 at 05:17
  • Hi I tried the following:
    protected void processMouseEvent(MouseEvent e) { switch (e.getID()) { case MouseEvent.MOUSE_PRESSED: startPoint = e.getPoint(); break; } super.processMouseEvent(e); }

  • protected void processMouseMotionEvent(MouseEvent e) { if (e.getID() == MouseEvent.MOUSE_DRAGGED) { Rectangle r = getVisibleRect(); Point p = e.getPoint(); int dx = (startPoint.x - p.x); int dy = (startPoint.y - p.y); Rectangle aRect = new Rectangle(r.x + dx, r.y + dy, r.width + dx, r.height + dy); scrollRectToVisible(aRect); } } – george b Dec 10 '10 at 09:28
  • It is not allowing me to put the code in order, am I doing it correctly? – george b Dec 10 '10 at 09:29
  • the code is not formatted, this text box is not allowing to format the code the way i did in the first post; but these are the two methods I override for dragging. with these two methods the dragging is not working [it works for a jtable]. can you please tell me where i am going wrong? – george b Dec 13 '10 at 04:47
