EnumFontFamExProc
[Now
Supported on Windows NT]
The EnumFontFamExProc
function is an application-supplied callback function that processes the fonts
enumerated by the EnumFontFamiliesEx function. The system calls this callback
function once for each enumerated font.
int CALLBACK
EnumFontFamExProc(
|
ENUMLOGFONTEX *lpelfe, |
// pointer
to logical-font data |
|
NEWTEXTMETRICEX *lpntme, |
// pointer
to physical-font data |
|
int FontType, |
// type of
font |
|
LPARAM lParam |
//
application-defined data |
|
); |
|
Parameters
lpelfe
Points to an ENUMLOGFONTEX structure that contains
information about the logical attributes of the font.
lpntme
Points to a
structure that contains information about the physical attributes of a font.
The function uses the NEWTEXTMETRICEX structure for TrueType fonts; and the TEXTMETRIC structure for other fonts.
Windows
95: The NEWTEXTMETRICEX
structure is not implemented. Use NEWTEXTMETRIC instead.
FontType
Specifies the
type of the font. This parameter can be a combination of these values:
DEVICE_FONTTYPE
RASTER_FONTTYPE
TRUETYPE_FONTTYPE
lParam
Specifies the
application-defined data passed by the EnumFontFamiliesEx function.
Return Values
The return
value must be a nonzero value to continue enumeration; to stop enumeration, the
return value must be zero.
Remarks
Unlike the EnumFontFamProc
callback function, EnumFontFamExProc receives extended information about
a font. The ENUMLOGFONTEX structure includes the localized name of the
script (character set) and the NEWTEXTMETRICEX structure includes a
font-coverage signature.
