[news.eclipse.platform.swt] Re: Question about ActionContributionItem

[Paul Webster <pwebster@xxxxxxxxxx>]

It's specifically designed that way.

A MenuManager and its associated IContributionItems are the "model" that 
backs one specific Menu and its MenuItems.  If you are only writing 
JFace+SWT, you will need to create a MenuManager per SWT Menu you need 
to create.  You can put the same IActions in multiple MenuManagers, but 
an ActionContributionItem must belong to one MenuManager (unless it's a 
dropdown, then it won't work).

That's why eclipse then adds extensions on top of the JFace support. 
i.e.  org.eclipse.ui.menus or org.eclipse.ui.popupMenus allows you to 
declaratively contribute the same menu structures to multiple context menus.

Later,
