Detailed Description

Base event class providing the core functionality of the Kanzi input events.

Declares the core event types used in Kanzi.

Use this class to create events that, in addition to the even type, do not require arguments. For example, the events InputEvent::ApplicationPaused, InputEvent::ApplicationSleep, InputEvent::ApplicationWakeup, and InputEvent::DebugToggleHud do not have a specialized event class, because they do not have additional arguments.

Mark the event handled by calling markHandled() method. An event marked as handled is is excluded from other event handlers.
