Member Function Documentation

void CEGUI::IrrlichtRenderTarget::activate ( )

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.

Implements CEGUI::RenderTarget.

Reimplemented in CEGUI::IrrlichtTextureTarget.

void CEGUI::IrrlichtRenderTarget::deactivate ( )

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.

Implements CEGUI::RenderTarget.

Reimplemented in CEGUI::IrrlichtTextureTarget.

void CEGUI::IrrlichtRenderTarget::draw ( const GeometryBuffer & buffer )

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.

Implements CEGUI::RenderTarget.

void CEGUI::IrrlichtRenderTarget::draw ( const RenderQueue & queue )

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.

Implements CEGUI::RenderTarget.

const Rect& CEGUI::IrrlichtRenderTarget::getArea ( ) const

virtual

Return the area defined for this RenderTarget.

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

Implements CEGUI::RenderTarget.

void CEGUI::IrrlichtRenderTarget::setArea ( const Rect & area )

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.

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.
