Class MouseOverService

java.lang.Object

io.apiman.manager.ui.client.local.services.MouseOverService

@ApplicationScoped
public class MouseOverService
extends Object

A service that allows widgets to register for mouse-in and mouse-out events. This is here because the built-in support for mouse-in and mouse-out in GWT is not bullet-proof. Sometimes you can get the mouse-in event but not the mouse-out event. This service watches the mouse move around the screen (captures all mouse movement) and then does its own calculations and tracking.
