Create extendable PopupMenu for an SWT Component via EMenuService [message #1220010]

Hello,

i'm trying to add a (Popup)Menu for an SWT component (NatTable).
it should be possible to add an menu item to it via extensions.

afaik i have to create a menu via EMenuService and register an SWT component with an given ID (then the service should create the menu and return it to me)

here is the code i use:
Quote:

Create a menu for this control and hook it up with the MPopupMenu.

does it mean it creates the menu itself or must it already exist?

e4popupMenu = menuService.registerContextMenu(natTable, menuId);

i checked for nullpointers:
menuService is not null
natTable is not null
menuId is not null
but the resulting e4popupMenu is null

can anyone explain me why this happens?

before i switched to e4 i did it with MenuManager, and this worked fine :-/
i was even able to gain direct access to an Menu (no more possible as i get an MPopupMenu? or can i get from this one to my 'classic' Menu)

Your menu is a part menu right?

So does the Part-Model hold a Menu with this ID? Did you debug into the
code?

tom i hope i understand your question right:
Quote:

in my manifest.mf i got an extension
org.eclipse.ui.menus
with location URI menu:xxx.views.site.listview.menu
(this extension contains a command - which i expect to show up in the menu)

Quote:

i did debug/search for mistakes in my code but not in eclipse code.

So you are running the compat layer? You did not say this in your first
post!

I'd suggest to bring up the live application model editor to find out if
the MPopupMenu is there and with what ID.

yes, i am using the compatibility layer (sorry forgot to mention this)
when running the liveeditor it did not show me an menu contribution.

so i added one in my plugin.xml

<menuContribution
            allPopups="false"
            locationURI="menu:xxx.views.site.listview.menu">
         <command
               commandId="xxx.views.site.commands.doSomething"
               icon="icons/icon.png"
               label="%doSomething"
               style="push">
         </command>
     </menuContribution>

after launching the app again, the only entry i can find which is connected to my specified view id is this:

id: org.eclipse.core.internal.registry.ConfigurationElementHandle@10e
parent-id: xxx.views.site.listview.menu

it seems i am missing the menu itself (specified parent-id)
how do i do so?

Well you are using "menu:" as the protocol which contradicts what you
are argueing about (Context/Pop-Menus). Are you sure you don't want
"popup:"?

do you mean simply change it to:
NOTE: this is extension point org.eclipse.ui.menus

<menuContribution
            allPopups="false"
            locationURI="popup:xxx.views.site.listview.menu">
         <command
               commandId="xxx.views.site.commands.doSomething"
               icon="icons/icon.png"
               label="%doSomething"
               style="push">
         </command>
     </menuContribution>

or do i need to move it to extension point org.eclipse.ui.popupMenus?
if so, what do i specify as id and parent id? (as the viewer which gets created by my gui has no id)

sorry if those questions are kind of dumb, but most tutorials handle e3 version or e4 versions, was not able to find a 'mixture' with compatibility layer, as i do use it.

http://wiki.eclipse.org/Menu_Contributions#popup. I'm not sure how this
stuff is handled in the compat layer but IIRC you need to register
context menus getSite().registerContextMenu(....) in your ViewPart, not?

exactly this is what i try to do (but i do not register through the getSite() because i have none - i register through the EMenuService - or is this the Wrong service?).
but the returned MPopupMenu is null.

You can not register through EMenuService, there you can only retrieve
an already register MPopupMenu. So if you are on the compat layer why
don't use getSite()? What you need is a MPopupMenu in your views
Menu-List. Who is contributing the MPart instance?

i am on the compatibility layer because i was not able to do everything needed in pure E4 (due bugs, which are already reported in bugzilla)
so some things are from e3 code.

i got a PojoListView

public class PojoListView extends E4TableViewPartTemplate<Site> {
	public static final String ID = "xxx.views.site.listview".intern(); //$NON-NLS-1$

	@Inject
	public PojoListView(Composite parent, EMenuService menuService) {
		// all needed swt code here...
	}
}

and the E4-version of it:

public class E4ListView extends DIViewPart<PojoListView> {
	public E4ListView() {
		super(PojoListView.class);
	}
}

so i need to do getSite() from the E4ListView and pass the site() to super.getcomponent() etc...?
