Constructor & Destructor Documentation

FX::FXFont::FXFont ( FXApp a,
const FXString string 
)

Construct a font with given font description of the form:

fontname [ "[" foundry "]" ] ["," size ["," weight ["," slant ["," setwidth ["," encoding ["," hints]]]]]]

For example:

"helvetica [bitstream],120,bold,italic,normal,iso8859-1,0"

Typically, at least the font name, and size must be given for normal font matching. As a special case, raw X11 fonts can also be passed, for example:

"9x15bold"

Note: use of the raw X11 fonts is stronly discouraged.

FX::FXFont::FXFont ( FXApp a,
const FXString face,
FXuint  size,
FXuint  weight = FXFont::Normal,
FXuint  slant = FXFont::Straight,
FXuint  encoding = FONTENCODING_DEFAULT,
FXuint  setwidth = FXFont::NonExpanded,
FXuint  h = 0 
)

Construct a font with given name, size in points, weight, slant, character set encoding, setwidth, and hints.

The font name may be comprised of a family name and optional foundry name enclosed in square brackets, for example, "helvetica [bitstream]".


Member Function Documentation

static FXbool FX::FXFont::listFonts ( FXFontDesc *&  fonts,
FXuint &  numfonts,
const FXString face,
FXuint  wt = 0,
FXuint  sl = 0,
FXuint  sw = 0,
FXuint  en = 0,
FXuint  h = 0 
)
static

List all fonts matching hints.

If listFonts() returns true then fonts points to a newly-allocated array of length numfonts. It is the caller's responsibility to free this array using freeElms().
