    • dragEnter

      Invoked when the drag enters the component. Accepts the drag if it's a file which is being dragged, and changes the background color to give visual feedback.
      Specified by:
      dragEnter in interface DropTargetListener

    • dragExit

      public void dragExit(DropTargetEvent dte)

      drop in interface DropTargetListener

    • dropActionChanged

      public void dropActionChanged(DropTargetDragEvent dtde)
      Called if the drop action changes during the drag (e.g., by changing the modifier keys). Does nothing, as we treat copy and move identically.

      dropActionChanged in interface DropTargetListener

    • getCloseAllItem

      protected JMenuItem getCloseAllItem()
      Returns the "Close all document windows" menu item. This allows document windows to add themselves as listeners.
