About Knob of JScrollPane..

[tonia wang]

Hi All,
I have a problem about JScrollPane: how to do something when the scroll bar of JScrollPane is moved? For example,
public void mousePressed(MouseEvent e){
if(e.getSource()==jScrollPane)
txt.setText("scroll!");
}
I've read the doc: http://java.sun.com/docs/books/tutorial/uiswing/components/scrollpane.html
It says the scroll bar is called Knob. However, it does not says how to trigger the Knob when users move the Knob...
Appreciate for any help. Thanks a lot!
Best Regards,
Tonia.

Hi Tonia,
How about...

  
scrollPane.getHorizontalScrollBar().addAdjustmentListener(new AdjustmentListener() {
  public void adjustmentValueChanged(AdjustmentEvent evt) {
  // your code here
}
});

Hope this helps!
Abhik.
