void GSurface::Blt (  int  x, int  y, GSurface *  Src, GRect *  a = NULL )  [virtual]

Copy an image onto the surface. Parameters: x  The destination x coord y  The destination y coord Src  The source surface a  The optional area of the source to use, if not specified the whole source is used Reimplemented in GScreenDC, and GMemDC.

void GSurface::Box (  GRect *  a = NULL  )  [virtual]

Stroke a rectangle in the current colour. Parameters: a  The rectangle, or NULL to stroke the edge of the entire surface Reimplemented in GScreenDC.

void GSurface::FloodFill (  int  x, int  y, int  Mode, COLOUR  Border = 0, GRect *  Bounds = NULL )  [virtual]

Flood fill in the current colour (doesn't work on a GScreenDC). Parameters: StartX  Start x coordinate StartY  Start y coordinate Mode  Use GDC_FILL_TO_DIFFERENT, GDC_FILL_TO_BORDER or GDC_FILL_NEAR Border  Fill colour FillBounds  The bounds of the filled area or NULL if you don't care Reimplemented in GScreenDC.

void GSurface::Rectangle (  GRect *  a = NULL  )  [virtual]
