use Commands/Handlers in a non-Workbench window [message #335338]

Hi,

I've got a kind of dialog window here where I'd like to have a toolbar and
re-use some of the actions from the workbench in this. I've tried to create
a coolbarmanager and use a menu service to populate it, but this crashes as
the dialog in question is not a workbench window. Is there another way to
have it populated from commands specified in the plugin.xml or do I have to
go the "hardcode your actions in java code" route?

You can use the IMenuService from the IWorkbench to populate a
contribution manager. Specifically, a ToolBarManager or MenuManager.
The code to populate a CoolBarManager (more or less) comes from
somewhere else.

It's unlikely you would be able to populate the main URIs (as described
in MenuUtil) but you should be able to define your own dialog-specific
URIs and use them.

I've found the relevant code that does this for the workbench window,
however using the same code in my dialog causes a null-pointer-exception
when trying to fetch the menu service:

IWorkbench workbench = PlatformUI.getWorkbench();
IServiceLocatorCreator slc = (IServiceLocatorCreator) workbench
.getService( IServiceLocatorCreator.class );
IServiceLocator serviceLocator = slc.createServiceLocator(
workbench, null,
new IDisposable() {
public void dispose()
{
final Shell shell = getShell();
if ( ( shell != null ) && !shell.isDisposed() ) {
close();
}
}
} );

IMenuService menuService = (IMenuService) serviceLocator.getService(
IMenuService.class );
menuService.populateContributionManager( "myid" );

java.lang.NullPointerException

In 3.4 (and so far in 3.5) you wouldn't create a new IServiceLocator ...
you would have to use the menu service from the IWorkbench, and then
release your ContributionManagers when your dialog goes away.

We will hopefully fix the NPEs in 3.5:

I've finally made this work, I simply had to supply the workbenchwindow to
createServiceLocator instead of the workbench.

And indeed using a CoolbarManager/CoolBar doesn't seem to work - at least
there's no toolbar visible. However replacing "C" with "T" and using a
toolbar works like a charm.

Ah, indeed that also works and allows me to avoid the usage of internal
classes.

One other minor thing is that I needed to provide the complete uri thats
used in the xml file, including the "toolbar:" prefix. And that wasn't
quite that easy to find out unfortunately ;)
