Programmatic Contribution Factories not supported [message #760907] Mon, 05 December 2011 14:51 Go to next message

Hi

I have a question concerning the compatibility layer and menu contribution factories.
In eclipse 3.7 we extended the ExtensionContributionFactory to programmatically contribute CommandContributionItems using the org.eclipse.ui.menus extension point.

As far as I can see this is not yet supported in the compatibility layer of our eclipse version (Build id: 20111110-1543).
When I check org.eclipse.ui.internal.menus.MenuPersistence there is some removed (commented out) code in the readAdditions() method together with a system-out informing that these factories are not supported.

Now to my question:
Is it planned to integrate this feature in a later build?
If yes: what is the plan on that? By when can we expect to make use of menu contribution factories?
If no: what is the alternative to use?

Thanks
Matthias

One work around might be to provide an MMenuContribution object. It should be straight forward.

Or you could take a stab at implementing it and contributing it back -- it should also be pretty straight forward.

Hi Brian

As we from Eclipse Scout are trying hard to maintain backward compatibility with 3.x (all our productive code is there) using MMenuContribution does not seem to be a valid option. So far we were assuming that all public API will be supported by the compatibility layer. This is working great in our case, except for the programmatic contribution factories.

To futher track this issue we opend bug 365903. Many thanks for quickly assigning target milestone M5!

Matthias

We will support programmitic contribution factories in 4.2 (and in Eclipse 4 they're done differently, via snippets or ModelProcessors or IEventBroker event handlers).


But I've gotta ask, why are you using them? What functionality do they give you over org.eclipse.ui.menus and something like the compound element (a org.eclipse.ui.actions.CompoundContributionItem) or a org.eclipse.ui.menus.CommandContributionItem and a org.eclipse.ui.commands.IElementUpdater?
