Detailed Description

Defines interface to some surface that can be rendered to. Concrete instances of objects that implement the RenderTarget interface are normally created via the Renderer object.

Member Function Documentation

virtual void CEGUI::RenderTarget::activate ( )

pure virtual

Activate the render target and put it in a state ready to be drawn to.

Note: You MUST call this before doing any rendering - if you do not call this, in the unlikely event that your application actually works, it will likely stop working in some future version.

Implemented in CEGUI::Direct3D9TextureTarget, CEGUI::OpenGLWGLPBTextureTarget, CEGUI::Direct3D10TextureTarget, CEGUI::Direct3D11TextureTarget, CEGUI::IrrlichtTextureTarget, CEGUI::OpenGL3FBOTextureTarget, CEGUI::OpenGLESFBOTextureTarget, CEGUI::DirectFBRenderTarget, CEGUI::OpenGLFBOTextureTarget, CEGUI::OpenGLGLXPBTextureTarget, and CEGUI::OpenGLApplePBTextureTarget.

virtual void CEGUI::RenderTarget::deactivate ( )

pure virtual

Deactivate the render target after having completed rendering.

Note: You MUST call this after you finish rendering to the target - if you do not call this, in the unlikely event that your application actually works, it will likely stop working in some future version.

Implemented in CEGUI::Direct3D9TextureTarget, CEGUI::OpenGLWGLPBTextureTarget, CEGUI::Direct3D10TextureTarget, CEGUI::Direct3D11TextureTarget, CEGUI::IrrlichtTextureTarget, CEGUI::OpenGL3FBOTextureTarget, CEGUI::OpenGLESFBOTextureTarget, CEGUI::DirectFBRenderTarget, CEGUI::OpenGLFBOTextureTarget, CEGUI::OpenGLGLXPBTextureTarget, and CEGUI::OpenGLApplePBTextureTarget.

virtual void CEGUI::RenderTarget::draw ( const GeometryBuffer & buffer )

pure virtual

Draw geometry from the given GeometryBuffer onto the surface that this RenderTarget represents.

Parameters

buffer GeometryBuffer object holding the geometry that should be drawn to the RenderTarget.

Implemented in CEGUI::DirectFBRenderTarget.

virtual void CEGUI::RenderTarget::draw ( const RenderQueue & queue )

pure virtual

Draw geometry from the given RenderQueue onto the surface that this RenderTarget represents.

Parameters

queue RenderQueue object holding the geometry that should be drawn to the RenderTarget.

Implemented in CEGUI::DirectFBRenderTarget.

virtual const Rectf& CEGUI::RenderTarget::getArea ( ) const

pure virtual

Return the area defined for this RenderTarget.

Returns: Rect object describing the currently defined area for this RenderTarget.

Implemented in CEGUI::DirectFBRenderTarget.

virtual bool CEGUI::RenderTarget::isImageryCache ( ) const

pure virtual

Return whether the RenderTarget is an implementation that caches actual rendered imagery.

Typically it is expected that texture based RenderTargets would return true in response to this call. Other types of RenderTarget, like view port based targets, will more likely return false.

Returns

true if the RenderTarget does cache rendered imagery.
false if the RenderTarget does not cache rendered imagery.

Implemented in CEGUI::OpenGLViewportTarget, CEGUI::Direct3D9ViewportTarget, CEGUI::OpenGLESViewportTarget, CEGUI::Direct3D9TextureTarget, CEGUI::Direct3D10TextureTarget, CEGUI::Direct3D11TextureTarget, CEGUI::IrrlichtTextureTarget, CEGUI::Direct3D10ViewportTarget, CEGUI::OgreWindowTarget, CEGUI::Direct3D11ViewportTarget, CEGUI::OpenGLESFBOTextureTarget, CEGUI::OpenGLTextureTarget, CEGUI::DirectFBRenderTarget, CEGUI::NullTextureTarget, CEGUI::OgreTextureTarget, and CEGUI::IrrlichtWindowTarget.

virtual void CEGUI::RenderTarget::setArea ( const Rectf & area )

pure virtual

Set the area for this RenderTarget. The exact action this function will take depends upon what the concrete class is representing. For example, with a 'view port' style RenderTarget, this should set the area that the view port occupies on the display (or rendering window).

Parameters

area	Rect object describing the new area to be assigned to the RenderTarget.

Note: When implementing this function, you should be sure to fire the event RenderTarget::EventAreaChanged so that interested parties can know that the change has occurred.

Exceptions

InvalidRequestException May be thrown if the RenderTarget does not support setting or changing its area, or if the area change can not be satisfied for some reason.

Implemented in CEGUI::DirectFBRenderTarget.

Member Data Documentation

const String CEGUI::RenderTarget::EventAreaChanged

static

Event to be fired when the RenderTarget object's area has changed. Handlers are passed a const RenderTargetEventArgs reference with RenderTargetEventArgs::target set to the RenderTarget whose area changed.
