How to hide Tree node according to some Criterions

[sindy lee]

I saw the example under : http://www.java2s.com/Code/Java/Swing-Components/InvisibleNodeTreeExample.htm

Now i want to hide many nodes at the same time according to some conditions(for example: Date, after a mouse click action on a calendar, some nodes in this tree should be hided), but not hiding just only one node and only after user selection. How can i do that? I thought, that i can't do that without "tree selection", But I hope i was wrong, there must be some solutions.

Thanks
