Detailed Description

This class simplify initialization / finalization of the overlay system.

OGRE root did this steps before the overlay system transformed into a component.

Remarks

Before you create a concrete instance of the OverlaySystem the OGRE::Root must be created but not initialized. In the ctor all relevant systems are created and registered. The dtor must be called before you delete OGRE::Root. To make the overlays visible (= render into your viewports) you have to register this instance as a RenderQueueListener in your scenemanager(s).

Member Function Documentation

preRenderQueues()

virtual void Ogre::RenderQueueListener::preRenderQueues ( )

inlinevirtualinherited

Event raised before all render queues are processed.

postRenderQueues()

virtual void Ogre::RenderQueueListener::postRenderQueues ( )

inlinevirtualinherited

Event raised after all render queues are processed.

renderQueueEnded()

virtual void Ogre::RenderQueueListener::renderQueueEnded ( uint8  queueGroupId, const String &  invocation, bool &  repeatThisInvocation  )

inlinevirtualinherited

Event raised after a queue group is rendered.

Remarks

This method is called by the SceneManager after each queue group is rendered.

Parameters

queueGroupId	The id of the queue group which has just been rendered
invocation	Name of the invocation which is causing this to be called (

RenderQueueInvocation)

Parameters

repeatThisInvocation

A boolean passed by reference which is by default set to false. If the event sets this to true, the queue which has just been rendered will be repeated, and the renderQueueStarted and renderQueueEnded events will also be fired for it again.
