disable selection in List? [message #462005]

How can I disable selection in a List?

I have a org.eclipse.jface.viewers.ListViewer, which displays some strings.
I want my users to be able to scroll horizontally and vertically; but I do
not want them to be able to select items in the list.

I tried simply disabling the List control, but that caused the scrollbars to
be disabled too. I haven't yet tried catching the selection event and
forcing the selection back to null, because I am concerned that may cause
flickering or other odd behaviors on some platforms.

Thanks!

There isn't a way to do this other than to put back the selection after the
user selects it.

Here's a code example for that:

List list = new List (parent, SWT.NONE);
list.add("Element");
list.addSelectionListener(new SelectionListener () {
  @Override
  public void widgetSelected(SelectionEvent e) {
    List l = (List) e.widget;
    l.deselectAll();
  }
  @Override
  public void widgetDefaultSelected(SelectionEvent e) {}
});
