Detailed Description

Implementation of IUI_FONT.

A bitmapped front with variable-width characters.

Uses texture and font width data generated by bitmap font builder: http://lmnopc.com/bitmapfontbuilder/ All fonts must be full 256 character ascii, 16 characters per row, 16 characters per column.

Member Function Documentation

bool CUI_VarBMFont::RenderText (  double  dtime, IUI_Renderer *  renderer, char *  text, unsigned int  columns, unsigned int  rows, unsigned int  startColumn, unsigned int  startRow, bool  wrap, unsigned int &  textColumns, unsigned int &  textRows, bool  invert = false, unsigned int  cursorPosition = 0, unsigned short  cursorType = UI_CURSOR_NONE )  [virtual]

Render specifying number of rows & columns and where to start. Used by CUI_TextBox Much more useful for multiline text chunks Implements IUI_Font.

bool CUI_VarBMFont::RenderText (  double  dtime, IUI_Renderer *  renderer, char *  text )  [virtual]

Base implementation. Default text renderer. Everything must fit into [0,1] unit square. Useful for buttons and simple labels Implements IUI_Font.
