Emitted at the start of each application update cycle.

Signal that emits before the app quit process begins. If any slots return false then the app quitting is canceled.

Returns whether the App is in full-screen mode or not.

Sets whether the active App is in full-screen mode based on fullScreen .

Returns the number of seconds which have elapsed since application launch.

Returns the number of animation frames which have elapsed since application launch.

Returns whether the app is registered to receive multiTouch events from the operating system, configurable via Settings at startup. Disabled by default on desktop platforms, enabled on mobile.

Returns whether Windows created on a high-density (Retina) display will have their resolution doubled, configurable via Settings at startup. Default is true on iOS and false on other platforms.

Returns a DataSourceRef to an application asset. Throws a AssetLoadExc on failure.
