I am using JFace treeviewer, would like to know how to disable the ability to collapse items and how to remove the collapsible icon.

    You can't remove the icon ('twistie') shown on the tree nodes. – greg-449 Aug 23 '16 at 06:50
  • are there widgets similar to the tree (indented) without collapse property or the icon? but items should be selectable... – Divya Dev Aug 23 '16 at 10:21
  • You could always just use a TableViewer with spaces at the start of the rows. Maybe Eclipse [NatTable](https://eclipse.org/nattable/) can do something. – greg-449 Aug 23 '16 at 10:49
  • doesnt help.. any other suggestions? What i need is to remove the twistie but keep the expanded look and indentation. – Divya Dev Aug 24 '16 at 10:40
  • convert your treeViewer to tableViewer is actually the best way to achieve what you want – Kuku Jul 03 '18 at 06:15

Restricting all key events on Tree looks promising but you would loose navigating the tree structure and expand/collapse on tree node and all other functionality.

tree.addKeyListener(new KeyAdapter() { @Override public void keyPressed(KeyEvent e) { e.doit = false; } });

Or also if you use JTree, 

JTree jtree = new JTree();
jtree.setToggleClickCount(0);
