Context menu in SelectionTreeView [message #1703761]

Have worked to this point with savable TreeViews. Due to the multiple kinds of EMF resources I have for a project I now need to use SelectionTreeView instead.

I see that there are no context menus on the EMF elements visualized in a SelectionTreeView. Is there a way to add the menus?

Hi John,
did you see the "menu" part on the documentation?
https://www.eclipse.org/emf-parsley/documentation.html#par12

We are working on that stuff to simplify the APIs..
They'll be available with the next release (and in the nightly updatesite ASAP).

Cheers.
Francesco

Hi Francesco,

Yes, I am familiar with that part of the documentation.

I have to this point worked with both the DSL and the non-DSL types of projects and have done a lot of menu customization. I tried to do the same things to customize menus in non-DSL SelectionTreeView and SelectionTreeForm based Parsley projects but could not get any ContextMenus to show.

I even tried creating a simple DSL based Parsley project that uses a SelectionTreeView but could not get it to show any ContextMenus either.

Here is my Parsley DSL from this project:

import com.verticon.parsley.selectionTreeViewTest.SelectionTreeViewTestOnSelectionTreeView
import com.verticon.im.Location

/* com.verticon.parsley.selectionTreeViewTest Emf Parsley Dsl Module file */
module com.verticon.parsley.selectionTreeViewTest {
	
	parts {
		viewpart com.verticon.parsley.selectionTreeViewTest {
			viewname "SelectionTreeViewTest"
			viewclass SelectionTreeViewTestOnSelectionTreeView
		}
	}
	menuBuilder{
			menus{
				Location-> #[
					submenu("Edit",#[
						actionCopy,
						actionCut,
						separator,
						actionPaste
					])
				]
			}
	}
			
}

Perhaps this is a bug?

thanks
John

Hi John

Francesco was referring to the section "Contextual Menu" not to the
"Menu Builder"; the custom menu builder you implemented is fine, but in
Parsley we automatically set context menus only on viewers inside a
"saveable view", not the ones inside "on selection views"; this is
because saveable views act on a resource and are meant to be editable,
while on selection views are usually used in read-only mode (at least,
we found this default behavior sensible :)

If you want the context menu on a viewer (inside any view that is not a
saveable one), you need to setup it yourself with the Java lines
documented in the section "Contextual Menu"; you also need to override
menuAboutToShow; you may want to have a look at

http://git.eclipse.org/c/emf-parsley/org.eclipse.emf-parsley.git/tree/plugins/org.eclipse.emf.parsley.views.common/src/org/eclipse/emf/parsley/views/AbstractSaveableViewerView.java

which is how we setup the context menu on saveable views.

As Francesco said, we're working on making this API much easier to use
and it should only take fewer lines to have a context menu on a viewer
(even without menuAboutToShow).

Please let us know if this fixes your problem.

cheers
Lorenzo

Hi Lorenzo,

Finally got it to work with:

       @Override
	public void menuAboutToShow(IMenuManager menuManager) {
		actionBarContributor.setActivePart(this);
		actionBarContributor.menuAboutToShow(menuManager);
		treeActionBarContributor.menuAboutToShow(menuManager);
	}

	@Override
	public void createPartControl(Composite parent) {
		super.createPartControl(parent);

		AdapterFactoryEditingDomain editingDomain = (AdapterFactoryEditingDomain) editingDomainProvider.get();
		treeActionBarContributor.initialize(editingDomain);
		viewerInitializer.addContextMenu(getViewer(), treeActionBarContributor, editingDomain, this);
		getViewer().addSelectionChangedListener(treeActionBarContributor);

		viewerInitializer.addMouseListener(getViewer());

		makeActions();
		contributeToActionBars();
	}

thanks for the help,
John

Great! :)

please, keep an eye on
https://bugs.eclipse.org/bugs/show_bug.cgi?id=455727 which should
simplify the overall process.

cheers

Hi

Please have a look at the new release 0.5.0 which is already available,
and at the updated documentation (and migration guide). The procedure
is much simpler now :)

cheers
