Hi, Friends:
I have following code it imports myEclipse’s packages, but when I tried to write it in myEclipse IDE, it shows red,

import org.eclipse.swt.dnd.*; 
   
 // Enable a label as a Drag Source 
 final Label dragLabel = new Label(shell, SWT.BORDER); 
 dragLabel.setText("text to be transferred"); 
   
 // Allow data to be copied or moved from the drag source 
 int operations = DND.DROP_MOVE | DND.DROP_COPY; 
 DragSource source = new DragSource(dragLabel, operations); 
   
 // Provide data in Text format 
 Transfer[] types = new Transfer[] {TextTransfer.getInstance()}; 
 source.setTransfer(types); 
   
 source.addDragListener(new DragSourceListener() { 
    public void dragStart(DragSourceEvent event) { 
       // Only start the drag if there is actually text in the 
       // label - this text will be what is dropped on the target. 
       if (dragLabel.getText().length() == 0) { 
           event.doit = false; 
       } 
    } 
    public void dragSetData(DragSourceEvent event) { 
      // Provide the data of the requested type. 
      if (TextTransfer.getInstance().isSupportedType(event.dataType)) { 
           event.data = dragLabel.getText(); 
      } 
    } 
    public void dragFinished(DragSourceEvent event) { 
      // If a move operation has been performed, remove the data 
      // from the source 
      if (event.detail == DND.DROP_MOVE) 
          dragLabel.setText(""); 
      } 
    } 
 }); 

here
[1]. there is no constructor like DragSource source = new DragSource(dragLabel, operations);
and constructor for:
final Label dragLabel = new Label(shell, SWT.BORDER);

only DragSource source = new DragSource();
and final Label dragLabel = new Label();

why??
where can I get them??
[2]. also, method source.setTransfer(types);
is not available.

how can I get this method when I import this package import org.eclipse.swt.dnd.*; ??

[3]. whole method
source.addDragListener(new DragSourceListener() { …}
is not available, how can I get it??

Thanks a lot
