Hi,

I am trying to programmatically populate a context menu in my application. This works well as I register my menu in my plugin.xml using

   <extension
         point="org.eclipse.ui.menus">
      <menuContribution
            locationURI="popup:viewID">
      </menuContribution>
   </extension>

and adding a ContributionFactory at runtime

		final IMenuService menuService = (IMenuService) PlatformUI.getWorkbench().getService(IMenuService.class);
		menuService.addContributionFactory(ContextMenuContributionFactory.getInstance(getEditorSite().getId()));

But what should I do when one of my ContributionItems wants to declare a submenu?

I guess my item needs to define a menuContribution programmatically and add another ContributionFactory to that.

If so, how can I define the menuContribution?

thanks
Christian

That kind of factory gets applied once (although in some cases of
context menu, it might get applied multiple times). You're better of
using a regular menuContribution and the <dynamic/> element for the
section of your contribution you'd like to contribute dynamically. But
a ContributionFactory is API and will work.

Add a MenuManager. That's a contribution item. If it's not dynamic in
nature, and you switched to a normal menuContribution instead of a
factory, you could simply define the submenu in the XML. But you can
define it in your ContributionFactory, you just become responsible for
filling it in.

Later,
PW
