CompoundContributionItem In E4

I have an implementation of CompoundContributionItem that I want to get to work in an pure E4 application. I found some kind of documentation for other IContributionItems, but not for this one.

What's the mechanism for implementing CompoundContributionItemin E4?

Solution

  • It's done via the @AboutToShow annotation:

    public class PluginEnablementContributionItem {

    @AboutToShow
    public void aboutToShow(List<MMenuElement> items) {
        MDirectMenuItem item = MMenuFactory.INSTANCE.createDirectMenuItem();
        item.setLabel("My Menu Item");
        item.setContributorURI("platform:/plugin/org.acme.project");
        item.setContributionURI("bundleclass://org.acme.project/org.acme.project.MyHandler");
        items.add(item);
    }

}
