Hello
I use the treeSelectionListener, for value change node,
but how can i catch the event when you open a node, is it possible, what is the interfaces to implements?
Adrien,
there is no hook in the current tree implementation to catch expand/collapse events. Besides, it is not necessary to build the complete tree in advance. It is also possible to implement the tree model in a way where children of a node are loaded just on demand.

Because i use this component for data value, and i can not build all the tree before drawn it (to long for user, to much request to database).
I would like to catch the event when an user open node, and inserted child of child in structure. So just build where the user go.
Thank a lot for your help.
