How to get an IContributionItem from the main menu [message #487944]

Hi

I am contributing my menus completely with the org.eclipse.ui.menus
extensionpoint for my rcp.

In order to test my menus (and handlers) with junit, I need to get a reference
to a particular IContributionItem. My problem now is, I cannot figure out a way
how I can get the main menu. It is no problem for view-menus (-toolbars, etc.).

IContributionItem newMenuItem = myView.getViewSite()
..getActionBars().getToolBarManager().find("my.view.id");

I am looking for something similar to that and I tried some ways, like
workbench.getActiveWorkbenchWindow().getShell().getMenu/getM enuBar

or via a ServiceLocator
IMenuService menuServive = (IMenuService) PlatformUI.getWorkbench()
..getActiveWorkbenchWindow().getService(IMenuService.class);

but both ways didnt give me the easy way of finding my contributionitem via the id.

I want to test this menus, first to learn TDD :-D, but also to bring my
application into a certain state, and test automatically if my menus are enabled
or not (according to the expressions).

regards

There's no suggested way to get IContributionItems from the main menu or main toolbar. You've found a way in the toolbar case although it's not always guarantee to work (since the IMenuService makes the dynamic in some cases).

For the main menu, some parts aren't even instantiated until the first time that particular SWT Menu is about to show.

As an aside, an IContributionItem cannot be executed, it's more in the nature of a renderer for a specific SWT Item.

The short answer is there is no way to get that information.

While I don't recommend it, If your menu has been instantiated you can use shell.getMenuBar() and walk the SWT Menu/MenuItem hierarchy until your find items you want.

I got that far on one point but as you say, it just didnt seem right.

I will try to test direclty against the handlers then (active or not)
according to the state of the application.

have a nice weekend
