OpenGUI::OgreFrameListener Class Reference

#include <Renderer_Ogre_Renderer.h>

List of all members.

Detailed Description

FrameListener that updates OpenGUI timing every frame.

An instance of this class is always created and managed by OgreRenderer.

During the "frameStarted" event this class will update OpenGUI's internal timer via System::updateTime(), then inject time delta events into each Screen that is auto timing via ScreenManager::updateTime().

Additionally, this object initiates automatic buffer reclamation processing at the end of frames via OgreRenderer::reclaimBufferMemory().

This FrameListener will always return true, and should never cause unintended exiting from Ogre::Root::startRendering()

virtual bool	frameEnded (const Ogre::FrameEvent &evt)
	calls OgreRenderer::reclaimBufferMemory() once per frame

performs the timing updates as specified in the class documentation

Note:

Because it is possible to have an OgreRenderer instance (containing an OgreFrameListener instance) without a complimenting OpenGUI::System, this automatic update process performs safety checks to ensure that each used Singleton exists before making the updates.
