automatic refreshing of J

Show all headers | View raw

  To: comp.lang.java.gui
Hello,

I'm having a hell of a time trying to get a JTree to automatically 
refresh to show that a node has been moved from one parent node to another.

I'm using the following statement to move the node to the new parent:
     model.getTreeModel().insertNodeInto(movedNode,
	newParent,newParent.getChildCount());

I'm trying to implement cut/copy/paste functionality and I'm working to 
get cut/paste functionality working first so in my paste method I test 
for the original operation. If it was a "cut" then I do the following:
     model.getTreeModel().removeNodeFromParent(movedNode);

However both of the statements above do not make the tree refresh 
automatically to show the changes. I thought using the above were 
supposed to do that?  I tried the reload() method of the tree model and 
of course when I do that the entire tree collapses and that isn't what I 
want (I have a feeling hardly anyone finds that "feature" of the 
reload() method useful).

Is reloading the tree the only way to make the change in the node's 
location visible in the tree? If so, what the hell is the point of those 
particular methods when I could just do, for an insertion, 
newParent.add(movedNode) instead?


thanks
