JFace TreeViewer flickering
문제
I'm trying to update the input of JFace TreeViwer periodically using setInput()
method. Also I use the
viewer.setExpandedElements(expandedElements);
viewer.setExpandedTreePaths(expandedTreePaths);
methods to save the state of the tree. But after each setInput()
call the TreeViewer flickers. How can avoid from flickering ?

Is the actual input changing? If not you can call refresh()
instead... or ideally use TreeViewers add/remove/update methods to avoid having to rebuild the entire tree.
You could try calling viewer.getTree().setRedraw(false)
before the calls to setExpand
, and then viewer.getTree().setRedraw(true)
after.
