Hi,

I try to use a JList as a drop target. I subclassed the JList and made a
MyList. Now I have a problem. The List works as a drop target... but
only every 2nd line (about). So I go with the cursor to the list a "no
drop" symbol appears. I move the cursor some pixels up or down.. and a
drop cursor appears. Moving again some pixels... "no drop" and so on.
Has anybody an idea???

Here some code:

public class MyList extends JList implements DropTargetListener{

  private ListModel listModel = new DefaultListModel();
  DropTarget dropTarget;

  public MyList() {
    super();
    dropTarget = new DropTarget(this,this);
  }

  public void setModel(ListModel listModel){
    super.setModel(listModel);
    this.listModel = listModel;
  }

  public ListModel getModel(){
    return listModel;
  }

  //DropTargetListener

  public void dragEnter (DropTargetDragEvent dropTargetDragEvent) {
    System.out.println("Drag Enter");	//Appears many times
    dropTargetDragEvent.acceptDrag (DnDConstants.ACTION_COPY_OR_MOVE);
  }
  public void dragExit (DropTargetEvent dropTargetEvent) {}
  public void dragOver (DropTargetDragEvent dropTargetDragEvent) {}
  public void dropActionChanged (DropTargetDragEvent
dropTargetDragEvent) {}
  public synchronized void drop (DropTargetDropEvent
dropTargetDropEvent) {
    try {
      Transferable tr = dropTargetDropEvent.getTransferable();
      ...// extract a String from the Transferable (a own object)	
      listModel.addElement(theElement); 
    }
    catch (Exception e) {
      e.printStackTrace();
      dropTargetDropEvent.rejectDrop();
    }
  }

}
