3x e4 Bridge, View, and getting the Shell [message #1029536]

Fri, 29 March 2013 20:52

Eclipse User

Incrementally trying to migrate 3.x RCP views over to e4 by
incorporating the 3x e4bridge in new plugin development.

One of the 3.x views dynamically builds a popup menu on the selected
items in a TreeView with new MenuManager("#PopupMenu"), using the
IWorkbenchPartSite to register selection providers and context menu. It
also uses the Active Shell when calling dialogs.

I have tried various ways to inject the ActiveShell, like:

@Inject @Named(IServiceConstants.ACTIVE_SHELL)
private Shell shell;

or

@Inject
private IShellProvider shellProvider;

but these do not work for me.

What is the proper way to do this? Any suggestions?

thanks,
John

I think we are simply not pushing this one into the context. Just to
make sure you run the e4 bridge in 3.x env or 4.x? File a bugzilla and
we'll try to hook it up.

Hi,

is there any news on this one?

Its always like gambling when trying to get the active shell to show some info window.

How to get the active shell properly?

As mentioned above, the following does not seem to work:

@Inject
	private IShellProvider shellProvider;
	@Inject
	@Named(IServiceConstants.ACTIVE_SHELL)
	private Shell shell;

I have also tried this one, but it is also not very reliable and I dont understand in which cases it works and when not.

public static Shell getShell() {

		IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
		if(window == null) {
			IWorkbenchWindow[] windows = PlatformUI.getWorkbench().getWorkbenchWindows();
			if(windows.length > 0) {
				return windows[0].getShell();
			}
		} else {
			return window.getShell();
		}
		return null;
	}
