AddOn gets the wrong shell [message #548859]

Hi anybody,

i recognized, that my AddOn-class gets the shell from the workbench, from where the app is started.

I added the following "AddOn" to my e4 app:

@PostConstruct
void hookListeners(Shell shell) {
shell.setText("Hooked");

After I recognized, the shell.setText doesn't works, I add the following code:

shell.setMaximized(true);
shell.addMouseMoveListener(new MouseMoveListener() {
@Override
public void mouseMove(MouseEvent e) {
System.out.println("move: " + e.x + ", " + e.y);
}
});

The mouse move is only called, if the mouse pointer is out of the app window.

I try it also with @Named(IServiceConstants.ACTIVE_SHELL) Shell shell. But the result is the same.

What should I do, to get underlaying Shell of my app?

I'm working on Mac with the following SDK;
e4 SDK 0.9.0.I20100718-2115

Greetings. Uwe

Hi,

At the moment the Addons are processed before the rendering is done.

An application beside that doesn't have only one shell but multiple ones
so your first code is not really making a lot of sense anyway.

The real use for Addons is give you access to the EventBus and hook your
EventHandler.

If you are interested in every creation of a Shell then you'll register
for a topic like this:

---------8<---------
@Inject
IEventBroker eventBroker;

@PostConstruct
void hookListeners() {
String topic = UIEvents.buildTopic(UIEvents.UIElement.TOPIC,
UIEvents.UIElement.WIDGET);
eventBroker.subscribe(topic, null, installHook, false);
}

@PreDestroy
void unhookListeners() {
eventBroker.unsubscribe(installHook);
}
---------8<---------

You could probably track the ActiveShell using method injection but
definately NOT not in the @PostConstruct.

Just one more note! You should NOT call setText() on the shell because
then you assume that an SWT-Shell is used to renderer the concept of a
window.

It's better to call MWindow#setLabel() which is the model element!
