java - How to update JTree elements -

-

i use jtree treenode extending defaultmutabletreenode.when add new node,i cant update jtree.any appreciated

adding node not enough, tree needs notified. correct way let model take care of adding/removing nodes, notify correctly tree on way.

in case of defaulttreemodel (which should 1 used in jtree if haven't made own treemodel), have method insertnodeinto(mutabletreenode newchild, mutabletreenode parent, int index), can use.
