Font Management

MGUI library provides ten preallocated (static) fonts in any platform which are referenced in the source code via macros. There are four fixed picth fonts:
  • DEFAULT_FONT
  • FIXED_SMALL
  • FIXED_MEDIUM
  • FIXED_LARGE
    • The others are proportional Times ed Helvetica (arial):
  • TIMES_SMALL
  • TIMES_MEDIUM
  • TIMES_LARGE,
  • HELV_SMALL
  • HELV_MEDIUM
  • HELV_LARGE
    • It's possible to load additional fonts via the MLoadFont() function call, specifying the font family, font size, bold and italic options. The font family is a case unsensitive string which specifies the font name. Since release 3.2 you can query MGUI to enumerate available font families (including ALL DOS versions) and load the desired font at run time.
    The font size specifies the desired font height. The returned font can have an actual height smaller than the requested one if the system doesn't support scaleable fonts or the font itself is fixed size. An application can load up to 22 new fonts.
    Note that, since any font loading request allocates an entry even if the the requested font has already been loaded before, it's highly recommended to unload unused font via the MUnloadFont() function call. If the MLoadFont() request cannot be satisfied, the function returns the predefined value DEFAULT_FONT as an error. This also offers the application the opportunity to continue without testing the returned font identifier since it's always valid.
