Conditional conext menu in fragment plugin [message #290770]

I'm working on a fragment plugin to extend an existing commercial plugin
and I've run into a bit of a stumbling block.

I want to add a refactor option to the right-click context menu in the
editor so that various refactoring options can be invoked.

I've got that part working fine using the org.eclipse.ui.popupMenus
extension point.

The problem is that the refactor options won't all be valid for any given
text selection. I can easily implement the checking logic in my actions
and tell the user that the action is invalid for the current selection,
but it would be a much better interface if I could disable the invalid
menu items before the user sees it.

I don't have access to the source code for the existing plugin, so I'm
wondering if there's a particular extension point that would allow me to
do what I want. I thought maybe there would be something that could be
added to the plugin at startup.

TIA

Your action is an IActionDelegate. When you receive the
selectionChanged(IACtion, ISelection) you can get the selection, test
it, and if not valid, take the IAction passed it and setEnable(false),
if it is valid do setEnable(true).
