virtual void ONE::render::Renderer2D::clearClipRegion (   )  [pure virtual]
 

clears the clip region

Everything will be drawn.

Implemented in ONE::render::G3DRenderer.

virtual void ONE::render::Renderer2D::drawRect (  const int &  x,
const int &  y,
const int &  w,
const int &  h,
const Color &  c
)  [pure virtual]
 

outlines a rectangle

Implemented in ONE::render::G3DRenderer.

virtual void ONE::render::Renderer2D::drawString (  const string &  s,
const int &  x,
const int &  y,
const Font &  f,
const Color &  c
)  [pure virtual]
 

draws a string

Parameters:
s the string that will be drawn
x the left edge of the text's bounding box
y the top edge of the text's bounding box
f the font used to draw s
c the color used to draw s

Implemented in ONE::render::G3DRenderer.

virtual void ONE::render::Renderer2D::endDrawing (   )  [pure virtual]
 

leaves 2D drawing mode

Implemented in ONE::render::G3DRenderer.

void ONE::render::Renderer2D::fillRect (  const int &  x,
const int &  y,
const int &  w,
