Stop Parts from being detachable

I would like to stop Parts from being detachable in Eclipse RCP 4.

Currently if I right click on a Part I can select detach. From this I can then close the tab even if the Part isn't Closeable. In RCP 3 when a detached View is closed it would then return back to its original location but now it closes completely.

How can I remove the option to detach a Part?

Also how can I stop a detached Part from being closed or make it return to its original location?

To stop parts being detachable I used a custom stack renderer and overrode the method to populate the tab menu. 

import java.util.Arrays;
import java.util.Optional;

import javax.annotation.PostConstruct;
import javax.inject.Inject;

import org.eclipse.e4.core.contexts.IEclipseContext;
import org.eclipse.e4.ui.internal.workbench.renderers.swt.SWTRenderersMessages;
import org.eclipse.e4.ui.model.application.ui.basic.MPart;
import org.eclipse.e4.ui.workbench.renderers.swt.StackRenderer;
import org.eclipse.swt.widgets.Menu;
import org.eclipse.swt.widgets.MenuItem;

public class UndetachableStackRenderer extends StackRenderer
{
    @Inject 
    private IEclipseContext context;

    @PostConstruct
    public void init() 
    {
        super.init(context);
    }

    @Override 
    protected void populateTabMenu(final Menu menu, final MPart part)
    {
        super.populateTabMenu(menu, part);

        final MenuItem[] menuItems = menu.getItems();

        final Optional<MenuItem> detachMenuItem = Arrays.stream(menuItems).filter(item -> item.getText().equals(SWTRenderersMessages.menuDetach)).findFirst();

        if(detachMenuItem.isPresent())
        {
            detachMenuItem.get().dispose();
        }
    }
}

I then added a Persisted State into the Part Stacks that I didn't want to show the Detach option.

If anybody is having trouble setting a custom stack renderer then my question here might help.

Checkout the bug : Eclipse Bug

I think you have to wait for the fix for NoDetach till it is available

For time being you can use NoMove tag which can stop dnd

Documentation

A part can be annotated with a NoMove tag to indicate that the drag-and-drop system should not allow the user to move this part. (Defined by IPresentationEngine.NO_MOVE)
