Detailed Description

FTLayout is the interface for layout managers that render text.

Specific layout manager classes are derived from this class. This class is abstract and deriving classes must implement the protected Render methods to render formatted text and BBox methods to determine the bounding box of output text.

virtual FTBBox FTLayout::BBox (  const wchar_t *  string, const int  len = -1, FTPoint  position = FTPoint() )  [pure virtual]

Get the bounding box for a formatted string. Parameters: string  A wchar_t string. len  The length of the string. If < 0 then all characters will be checked until a null character is encountered (optional). position  The pen position of the first character (optional). Returns: The corresponding bounding box. Implemented in FTSimpleLayout.

virtual FTBBox FTLayout::BBox (  const char *  string, const int  len = -1, FTPoint  position = FTPoint() )  [pure virtual]

Get the bounding box for a formatted string. Parameters: string  A char string. len  The length of the string. If < 0 then all characters will be checked until a null character is encountered (optional). position  The pen position of the first character (optional). Returns: The corresponding bounding box. Implemented in FTSimpleLayout.

virtual FT_Error FTLayout::Error (   )  const [virtual]

Queries the Layout for errors. Returns: The current error code.

virtual void FTLayout::Render (  const wchar_t *  string, const int  len = -1, FTPoint  position = FTPoint(), int  renderMode = FTGL::RENDER_ALL )  [pure virtual]

Render a string of characters. Parameters: string  wchar_t string to be output. len  The length of the string. If < 0 then all characters will be displayed until a null character is encountered (optional). position  The pen position of the first character (optional). renderMode  Render mode to display (optional) Implemented in FTSimpleLayout.

virtual void FTLayout::Render (  const char *  string, const int  len = -1, FTPoint  position = FTPoint(), int  renderMode = FTGL::RENDER_ALL )  [pure virtual]

Render a string of characters. Parameters: string  'C' style string to be output. len  The length of the string. If < 0 then all characters will be displayed until a null character is encountered (optional). position  The pen position of the first character (optional). renderMode  Render mode to display (optional) Implemented in FTSimpleLayout.
