ContextMenuProvider + selected editParts [message #157766]

Is it possible to know which editparts are selected in a
ContextMenuProvider? I want to be able to calculate which menus to show
based on this knowledge. Note that there is not enough information in the
SelectionAction since I need the set of (enabled) actions and the set of
selected edit parts.

Thanks.

James

What about selectionAction.getSelectedObjects(). This gives you a list
of the selected edit parts. The calculateEnabled() method of your
action(s) can use this to decide if they are enabled or not.

Guy,

Yes - I'm currently using that route, I was just wondering whether the
list of selected edit parts was scoped over the ContextMenuProvider.

Thanks anyway.

I don't understand the question. ContextMenuProvider contains the
EditPartViewer, so you just need to call getSelection()

Ok, I understand what you want to do. But I think the right way to do it
is through the action enabled/disabled route. If you don't want disabled
actions to show in your context menu then when your context menu
provider builds the menu prior to showing it should only add the actions
that are enabled.

JFace already provides a filter mechanism. You need to provide the filter
processor, and fill in the rules for your actions in the plugin.xml file.

The only reason to use this mechanism would be to prevent plug-in startup.
Otherwise, I'd just use the enablement technique we use in the examples.
