I think this was what Stacey was saying, but can you just update the
label property of the objects in the dp instead of the object its
self?
If nothing else works naturally, you could walk the list of tree
items to find out which ones are open.
You could have two trees that you swap whenever the language is
changed, and do a loop that calls getIsOpen on each node, and then
sets the state of the coresponding node in tree 2 by calling
setIsOpen. Then swaps the display. If the user changes the lang
again, swap back after the loop again (swapping tree1 for tree2,
etc). Or you could avoid the two trees by storing it in an array,
change DP, set values from array. But all of this is a bit of
overkill. This is just kind of fun now :)
loop
{
tree2.setIsOpen(tree2.getTreeNodeAt(i), tree1.getIsOpen
(tree1.getTreeNodeAt(i)), true, true);
}
Kind of a last resort, but might work (I didnt test the syntax, btw)
