Hi.
I'm having problems when I call refresh on a treeview.
I have a simple directory/file list program that is displayed in a JFace
treeview.
If I start my program and do an expandAll() on the tree, then manually
create a new file (in a seperate console window;eg. touch file.txt), then
call refresh on the tree view, the new file will be displayed in the tree
view - but all the nodes that appear after the new file in the treeview
have partially collapsed (they don't fully collapse, but expand to only
one level - they don't expand back to their previous state)? The tree that
appears above the new file is in its correct expanded state.
I call refresh as follows:
Object[] expandedObjs = tv.getExpandedElements();
tv.refresh();
tv.setExpandedElements(expandedObjs);
Have I missed something? I can't find any good documentation on how to use
the above functions correctly, so I may be doing this wrong? Maybe I need
to insert the file into the tree view using a different treeview function?
Thanks
Mark Robinson
