Class: EventManager
EventManager
An event manager handles the states related to certain events and can augment widget interaction. For example, the click manager will hide clicks when the object is dragging.
Event managers are lifecycle objects - they can start/stop. Their constructor
will always accept one argument - the widget. Other settings can be applied before
startEvent.
Ideally, you should access event managers after your widget has initialized. This is because it may depend on the widget's stage being assigned.
