Get lazy main menu items [message #560165]

Hi *,

in my application I have NavigationView with tree component filled by content of 'Workplace' part of main menu.
I used Eclipse RCP 3.2 and that worked just fine.
I get menu like this
MenuItem menuItem = getSite().getShell().getMenuBar().getItem(1);

and with small workaround set it as input for tree component.

Now I try to do the same thing in Helios 3.6 and my navigator tree stays empty because menu items aren't initialized in main menu until first call by user.

Can I change this behavior and load all menu items on application start?

If not then I should probably build this menu part dynamically ContributionItem?

Do you see another options?

Regards
Roman

There might be ways to inject SWT events into the menu and force it
instantiate, but the SWT part of the main menu bar is an implementation
detail. The improvements in lazy loading are what has made your access
to the implementation fail between 3.2 and 3.6.

You might be able to, if you could find out what code is generating the
submenu you are interested in. Have a look at
org.eclipse.ui.internal.ide.WorkbenchActionBuilder to see if it is added
to the main menu there.
