Method Summary
`boolean` | `mayMove(java.lang.Object scope, java.lang.Object node)` returns true, if node may be moved
`void` | `move(java.lang.Object scope, java.lang.Object item, int oldIndex, int newIndex)` called after the user has clicked on an item to move it.

Method Detail

### mayMove

    public boolean mayMove(java.lang.Object scope,
                           java.lang.Object node)

  returns true, if node may be moved

### move

    public void move(java.lang.Object scope,
                     java.lang.Object item,
                     int oldIndex,
                     int newIndex)

  called after the user has clicked on an item to move it. The element at `oldIndex` is removed from the array, so the size of the array is reduced by one. After that, the element is inserted at the index `newIndex`. A valid implementation would be:

         ArrayList al = ...
         Object o = al.remove(oldIndex);
         al.add(newIndex, o);

  Parameters:
    `scope` - the scope for the node to move (for convenience).
    `item` - the node to move (for convenience), which lives at position oldIndex
    `oldIndex` - the index of `item` before it was moved
    `newIndex` - the index of `item` after it has been moved
