to try and access the View menus and Toolbars.
Anyway I've been able to run a command when I give the ID to the handler
service. I've also been able to programatically get a list of all the
contribution items for a view.
Well now here is my problem. I need to either get physical menu item
widgets to trigger them as if being pressed, or I need to get the command
id. My problem is I haven't been able to get either of these. Personally
I like to be able to get both.
Any help would be appreciated.

PS I'm hoping Paul Webster will respond on this as he seems to be the
master of all around this topic.

Hmmm. If you can get the MenuManager or ToolBarManager for the view,
you can get a list of IContributionItems. Depending on the view, some
of them are ActionContributionItems, and aci.getAction().run() will run
them (most of the time). CommandContributionItem doesn't have getters
for most of its information, there isn't a general purpose need for them
(although I can see why swtbot could use them). As a matter of fact,
CommandContributionItem has no useful API above IContributionItem. The
only way to access information for CommandContributionItem would be to
use reflection to yank it out of the private member variables (messy at
the best of times).
The other option is to walk the SWT Menu/MenuItem hierarchy, but you
have to get it first (and I'm not sure where you are starting from, an
active IWorkbenchPart?). Once you have the menu item, executing is
straight forward (for non-dynamic menu cases):
item.notifyListeners(SWT.Selection, null);
But that won't handle the general case, only the 80% case. Is there a
specific direction you are trying to take?
Later,
PW
