Reuse of Menu Elements / MenuContributions [message #819246]

Hello,

is it possible to re-use MMenu elements?

I have two cases where this would help:
1) Use a menu (or parts of it) in the menu bar and as a popup
2) Use the same popup in multiple parts

What are "Menu Contributions" in the Application e4Xmi?

Greetings
Christoph

I think Popups are currently not supported. Did you make them work?

Hi Lars

yes.

Step 1) Create a Menu as a child of the Part with the Model Editor
Step 2) Edit the e4xmi directly and change the xsi:txpe from "menu:Menu" to "menu:PopupMenu"
Step 3) Hook the Menu to the control with EMenuService.registerContextMenu

That works great.

At the moment I am also using a MenuDetectListener on an SWT-Tree to switch the popup menu depending on the current selection. That works too, but raised the issue in question "re-using menu definitions".

Thanks for your reply on "Snippets". Is the usage of Menu, Toolbar and Trim Contributions similar to this approach? => Use a processor to copy the MMenuElements in a MenuContribution into all the places the menu should be available (i.e. as a View-Menu and as a Popup-Menu)?

Cool. Thanks for the tip with the context menu. I point Tom (Schindl) also to this discussion, he may want to adjust the model editor.

Yes, the other items (Menu, Toolbar and Trim Contribution) can be used similiar to Snippets IMHO.

This bug has already been fixed with 371549 by Brian some weeks ago so
if you are on an I-build or switch to M6 once it is out things should
just work.

Each MMenu or MMenuItem can only have one parent, so there must be a separate instance in each menu that you need.

MMenuContributions contain menu templates that can be added to regular menus and popup menus. They follow the same convention for specifying where to apply the template as the org.eclipse.ui.menus/menuContribution does.

Thanks again Christoph.

I added the creation of Popup-menus with the e4 tooling to my Eclipse 4 tutorial - Defining Popup Menus

I bring back the subject to life because I found in the Eclipse source code other ways to share menus that look like Eclipse 3 menu contributions.
I have tested them in my project and it works:

You can add MMenuContribution to a MApplication 'menuContributions' feature.
This MMenuContribution has a 'parentId' : the menu ID of the menu you want to complete and
menu items that will be added to a menu.

You can also add "popup:an.identifier" tags to MMenu and MPopupMenu elements.

With all these elements, the MMenuContribution will be added to a MMenu if:

the MMenu identifier equals the contribution parentId
parentId is 'popup' : the contribution will be added to ALL popup menus
the MMenu has a "popup:an.identifier" tag equals to the MMenuContribution parentId "an.identifier"

So to share a MMenuContribution to many MMenu elements you:

put a "popup:an.identifier" tags to MMenu
set parentId "an.identifier" on the MMenuContribution

The MMenuContribution also has a position attribute to specify where the contribution will be inserted.
