How to make SmartGWT TreeGrid reparent selectively allowed depending on nodes
原标题:

I have the following data in a SmartGWT TreeGrid object.

Home
 |-Room 1
 |-Room 2
    |-Table
    |-Chair

Reparenting is allowed by calling treeGrid.setCanReparentNodes(true);

I want to allow selectiv reparenting only: for example, it should be possible to move (drag&drop) the Table to Room 1, but it should not be possible to move the Room 1 into Room2 or the Chair into Home.

How can I selectively allow reparenting depending on the node type (or a node s attribute)?
