Constructor & Destructor Documentation

Redrawer (   )  [inline]

default ctor - sets viewport to whole actual window

Here is the call graph for this function:

virtual ~Redrawer (   )  [inline, virtual]

Redrawer (  uint  ox, uint  oy, uint  sx, uint  sy )  [inline]

Member Function Documentation

void doRedraw (   )

virtual void draw (   )  [protected, pure virtual]

actual draw - to be implemented in childs Shouldn't do clearing or glFinish the viewport is set to redrawer's range and X-form matrix is set to default 2D ortho (0,0,sizeX,sizeY) Implemented in KohonenAnalyzer, KohonenDraw, and ExKohonenDraw.

void setFullViewport (   )

sets viewport to full current window

void setViewport (  uint  ox, uint  oy, uint  sx, uint  sy )  [inline]

Todo: we could store the viewport in normalized values so it would be independent of window size ..
