Hi,

I'm trying to implement a login button in the toolbar which
has a label called "login" and after pressing + successfull
login it shows the user name.

My implementation contains:
* Command
* Handler
* Window Trim -> Trimbar -> Toolbar -> Handled tool item -> Handler/Command

How do I access this tool item?

Note:
I tried "ToolControl", but the css isn't applied and it looks awefull.

thanks in advance,
Muki

Hi Muki,
you can use the EModelService to get the MainToolbar.
Should look smth. like:

@Inject
private EModelService m_ModelService;
@Inject
private MWindow m_Window;

MApplication app = (MApplication)((EObject)m_Window).eContainer();
MToolBar mainToolbar = (MToolBar)m_ModelService.find("toolbar:org.eclipse.ui.main.toolbar", app);

mainToolbar.getChildren() should contain your login-item. The problem is that iam not sure if the Renderer will react on your MToolItem.setLabel("username") and updates the label of the Widget that was created for the MUIElement.
Bug 374568 for example shows that the Renderers do not react on every change yet.

The (imho) "bad" way would be to directly manipulate the widget which should work (already tried it for the MainMenu) and should look smth. like this:

((MenuItem)((Toolbar)mainToolbar.getWidget()).getItem(i)).setText("username")

You can also inject MApplication directly as the search root, it is not necessary to go through MWindow.

Also the update of the label should be autmatically done.
