How to make code work for previous versions

Question

Hello, i have written the code below using swing 1.4. I was wondering if anyone could help me by letting me know what to convert so i run run this on a machine with a lower java runtime (ie 1.22)
What i am trying to do is have a tree with a list of files, and when u click on a node, the tree will expand, and send the node name accross to another frame. Help is most appreciated. Thanks

hi!
you can get lead selection in the action handler then inset your code for currentContextElement.
wdContext.currentContextElement().getTableSorter().sort(wdEvent, wdContext.nodeXXX());
thanks
