java - How to add an image while we drag n drop tree item? -


i have tree number of childs , want drag , drop these child items on vertical panel. right working fine.the thing want know can add image in place of small icon comes @ time of dragndrop.

you need override newdragproxy() method of pickupdragcontroller in order provide own proxy widget (say, image) when drag starts.

do note need use setbehaviordragproxy(true) allow dragging proxies instead of original widgets (i.e., original widgets stay in place, , drag proxy of it, can style wish).
