E4 + SWT renderer in FullScreen mode? [message #695976]

Hi,

I would like to know where is the best place to call the SWT shell.setFullScreen(true) method to able my E4 RCP to start in fullScreen mode ?

I have tried to use lifeCycleURI, but I've discovered that it is processed before UI is get started...

I've start to investigate a solution with addOn (using the MinMaxAddOn as example) but I couldn't find out how could I have the main shell injected...

I would appreciate any help.

cheers

Cristiano

Hi,

I haven't tried it myself, but you could try to register a processor via the extension point org.eclipse.e4.workbench.model. Inside of the class you should be able to get the Shell by Injection:

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

@Execute
public void execute() {
	shell.setFullScreen(true);
}

Let me know if it works ...

Hi I could make it work using AddOns.
I've subscribed on UIEvents.UIElement.WIDGET and get the shell from it.

		ev5 = new EventHandler() {

			@Override
			public void handleEvent(Event event) {
				Object objElement = event
						.getProperty(UIEvents.EventTags.ELEMENT);
				Object objType = event.getProperty(UIEvents.EventTags.TYPE);
				Object objWidget = event.getProperty(UIEvents.EventTags.WIDGET);
				Object objNew = event.getProperty(UIEvents.EventTags.NEW_VALUE);
				Object objOld = event.getProperty(UIEvents.EventTags.OLD_VALUE);
				Object objAtt = event.getProperty(UIEvents.EventTags.ATTNAME);

				if (!(event.getProperty(UIEvents.EventTags.ELEMENT) instanceof MWindow))
					return;

				String attName = (String) event
						.getProperty(UIEvents.EventTags.ATTNAME);
				// Is this listener interested ?
				MWindow windowModel = (MWindow) objElement;
				// if (windowModel.getRenderer() != WBWRenderer.this)
				// return;

				// No widget == nothing to update
				Shell theShell = (Shell) windowModel.getWidget();
				if (theShell == null)
					return;
				
				theShell.pack(true);
				theShell.setMaximized(true);
//				theShell.setFullScreen(true);
			}
		};
		eventBroker.subscribe(UIEvents.buildTopic(UIEvents.UIElement.TOPIC,
				UIEvents.UIElement.WIDGET), ev5);
	}

It is entering on fullScreen properly, but the screen is not ok on my Mac.
The main toolbar is shorter (height) that the normal and my icons was trimmed. I think it is related to the top bar that is removed when it enter in fullscreen mode... (see attached picture)

any tip to help me to investigate this?

thanks

Cristiano
