EnumFontFamilies
The EnumFontFamilies
function enumerates the fonts in a specified font family that are available on
a specified device. This function supersedes the EnumFonts function.
int EnumFontFamilies(
HDC hdc, |
// handle to device
control |
LPCTSTR lpszFamily, |
// pointer to
family-name string |
FONTENUMPROC lpEnumFontFamProc, |
// pointer to
callback function |
LPARAM lParam |
// address of
application-supplied data |
); |
|
Parameters
hdc
Identifies
the device context.
lpszFamily
Points to a
null-terminated string that specifies the family name of the desired fonts. If lpszFamily
is NULL, EnumFontFamilies randomly selects and enumerates one font of
each available type family.
lpEnumFontFamProc
Specifies the
procedure-instance address of the application-defined callback function. For
information about the callback function, see the EnumFontFamProc
lParam
Points to
application-supplied data. The data is passed to the callback function along
with the font information.
Return Values
If the
function succeeds, the return value is the last value returned by the callback
function. Its meaning is implementation specific.
Remarks
The EnumFontFamilies
function differs from the EnumFonts function in that it retrieves the
style names associated with a TrueType font. With EnumFontFamilies,
information can be retrieved about unusual font styles (for example, Outline) that
could not be enumerated by using the EnumFonts function. Win32-based
applications should use EnumFontFamilies instead of EnumFonts.
For each font
having the typeface name specified by the lpszFamily parameter, the EnumFontFamilies
function retrieves information about that font and passes it to the function
pointed to by the lpEnumFontFamProc parameter. The application-defined
callback function can process the font information as desired. Enumeration
continues until there are no more fonts or the callback function returns zero.
