Detailed Description

template<typename T = RenderTarget>
class CEGUI::OgreRenderTarget< T >

Intermediate RenderTarget implementing common parts for Ogre engine.

Member Function Documentation

template<typename T = RenderTarget>

void CEGUI::OgreRenderTarget< T >::setOgreViewportDimensions

(

const Rectf &

area

)

Set the underlying viewport area directly - bypassing what the RenderTarget considers to be it's area - thus allowing the view port area used for rendering to be different to the area set for the target.

Parameters

area	Rect object describing the area to use in pixels.

Deprecated:

This function is deprecated and will be removed or changed considerably in future releases.

Member Data Documentation

template<typename T = RenderTarget>

bool CEGUI::OgreRenderTarget< T >::d_viewportValid

protected

true when d_viewport is up to date and valid.

Version

Beginning from Ogre 2.0 this indicates whether the workspace is up to date
