How to improve performance of expanding the jface treeviewer?

836 Views Asked by Sudeep At 24 April 2018 at 09:12

I have a JFace treeviewer with 7000+ nodes, when I perform expand all on the root element, it takes about 2 minutes to expand.

I have tried calling expandAll() and expandToLevel(Object, level), still the performance remains the same.

Is there a way to expand the tree in less time ?
