Is there any way I can ADD addDragSourceListener to JInternalFrame

Question

I want to use addDragSourceListener to the JInternalFrame. Is there any way i can use it
This s waht i am using;
JInternalFrame dFrameDrag = new JInternalFrame();
dFrameDrag.addDragSourceListener(new DragSourceListener(){
public void dragEnter (DragSourceDragEvent event) {
System.out.println( " dragEnter");
public void dragExit (DragSourceEvent event) {
System.out.println( "dragExit");
public void dragOver (DragSourceDragEvent event) {
System.out.println( "dragOver");
public void dropActionChanged ( DragSourceDragEvent event) {
System.out.println( "dropActionChanged");
public void dragDropEnd (DragSourceDropEvent event) {  
if ( event.getDropSuccess()){
System.out.println("Success");
When i am compiling this i am getting " Method addDragSourceListener(DragNDrop.1) not found in javax.swing.JInternalFrame"
I Know JInternalFrame does not support "addDragSourceListener" but i want to use it.
Can any one tell me a way how to Accomplish this task?

Ravi,
Your problem may reside in the fact that JDesktopPane has a dragmode property. Swing is already listening for mouse drags at that level so a JInternalFrame can be moved around. Therefore, you should use addDragSourceListener on your JDesktopPane and either determine which InnerFrame is affected or only react to mouse drags within your topmost. If this doesn't work to your satisfaction, you may need to extend DefaultDesktopManager and override some of the drag methods with your own custom code.
Hope this helps,
