Background image on main shell [message #992105]

Hi,

I want to draw an image on the main Shell of my e4 application, resizing it in proportion to the current size of the Shell. In e4, how do I listen for the creation of the main Shell, so that I can add a resize listener? Maybe I need to listen for the creation of the Workbench, but I can't figure out how to do that either.

You can do those things by listening to the event broker. http://git.eclipse.org/c/platform/eclipse.platform.ui.git/tree/bundles/org.eclipse.e4.ui.workbench.renderers.swt/src/org/eclipse/e4/ui/workbench/renderers/swt/WBWRenderer.java has all sorts of event types and also a size handler. Look in the method annotated with @PostConstruct.

thanks for your reply. How do I get the IEventBroker instance at app start-up? I tried to inject it in my plugin's activator, but apparently the framework does not inject into Activators:

@Inject
private IEventBroker eventBroker;

eventBroker was null when start() was called.
