Dear all,
I have a TableTreeViewer which contains a model representing a tree.
If I have a root node with two children (A & B) & B as to children (C &
D), we would have a TableTree looking like:
[-]Root
A
[-]B
C
D
where Root and B are collapsable. If the model changes such that A now has
a child, for some reason all of the tree collapses. I think its because I
am calling tableTreeViewer.refresh() rather than some sort of targetted
refresh() after the model change has occured.
How do I leave the rest of the TableTrees expansion state intact while
only revealing the new child?
Thanks,
Raj

Dear Raj
use the refresh(TreeTableItem A).
or set "TableTreeViewer.setExpandedState(TreeTableItem A, boolean
expanded);" .
Hope it helps...
