Constructor & Destructor Documentation

◆ FXFont() [1/2]

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.

◆ FXFont() [2/2]

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

◆ listFonts()

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().
