[news.eclipse.platform] Re: IContributionItems Access details

[Paul Webster <pwebster@xxxxxxxxxx>]

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,
