Detailed Description

This layer is responsible for traversing the tree of SceneNodes, drawing each node as it goes.

The SceneNode objects are owned by the ExampleViewerDelegate allowing multiple viewports to share the same data on the graphics card.

Member Function Documentation

virtual bool ExampleSceneLayer::event

(

const FnEventWrapper &

eventData

)

[virtual]

Processes UI events.

Called whenever a user interaction event occurs. This will be also propagated through the ViewerLayers of this ViewportLayer.

Parameters:

eventData

The event data (see FnEventWrapper).

Returns:

True if the event has been handled, in that case it will not be passed to the following layers. Otherwise false and the event will be passed to the following layers.
