OpenGUI::Brush_RTT::~Brush_RTT (   )  [virtual]

Destructor.

Member Function Documentation

void OpenGUI::Brush_RTT::appendRenderOperation (  RenderOperation &  renderOp  )  [protected, virtual]

Final output RenderOperations are passed to this function. It is up to specialized Brush implementations to capture final output with this function. At this point, the Brush is guaranteed to already to be active. Reimplemented from OpenGUI::Brush.

void OpenGUI::Brush_RTT::clear (   )  [inline]

public access to Brush::_clear()

void OpenGUI::Brush_RTT::emerge (  Brush &  targetBrush  )

sends the contents of this caching Brush into the output stream of the given Brush

const FVector2 & OpenGUI::Brush_RTT::getPPU_Raw (   )  const [virtual]

Returns the raw (uncorrected) PPU (pixels per unit) of this Brush. See also: Screen::getPPU() Implements OpenGUI::Brush.

const FVector2 & OpenGUI::Brush_RTT::getUPI_Raw (   )  const [virtual]

Returns the raw (uncorrected) UPI (units per inch) of this Brush. See also: Screen::getUPI() Implements OpenGUI::Brush.

bool OpenGUI::Brush_RTT::hasContent (   )  const [inline]

returns true if there is content stored that can be emerged

virtual bool OpenGUI::Brush_RTT::isRTTContext (   )  const [inline, virtual]

returns true if the brush context is a render to texture surface Implements OpenGUI::Brush.

void OpenGUI::Brush_RTT::onActivate (   )  [protected, virtual]

Called automatically when this Brush becomes the active Brush. Implements OpenGUI::Brush.

void OpenGUI::Brush_RTT::onClear (   )  [protected, virtual]

Called when this Brush has been told to clear the contents of its render surface. The Brush is guaranteed to be active at this point Implements OpenGUI::Brush.
