	13
	14	wxFontEnumerator enumerates either all available fonts on the system or only
	15	the ones with given attributes - either only fixed-width (suited for use in
	16	programs such as terminal emulators and the like) or the fonts available in
	17	the given \helpref{encoding}{wxfontencodingoverview}.
	18
	19	To do this, you just have to call one of EnumerateXXX() functions - either
	20	\helpref{EnumerateFacenames}{wxfontenumeratorenumeratefacenames} or
	21	\helpref{EnumerateEncodings}{wxfontenumeratorenumerateencodings} and the
	22	corresponding callback (\helpref{OnFacename}{wxfontenumeratoronfacename} or
	23	\helpref{OnFontEncoding}{wxfontenumeratoronfontencoding}) will be called
	24	repeatedly until either all fonts satisfying the specified criteria are
	25	exhausted or the callback returns FALSE.
	26
	27	\wxheading{Virtual functions to override}
	28
	29	Either \helpref{OnFacename}{wxfontenumeratoronfacename} or
	30	\helpref{OnFontEncoding}{wxfontenumeratoronfontencoding} should be overridden
	31	depending on whether you plan to call
	32	\helpref{EnumerateFacenames}{wxfontenumeratorenumeratefacenames} or
	33	\helpref{EnumerateEncodings}{wxfontenumeratorenumerateencodings}. Of course,
	34	if you call both of them, you should override both functions.

	55	\func{virtual bool}{EnumerateFacenames}{
	56	\param{wxFontEncoding }{encoding = wxFONTENCODING\_SYSTEM},
	57	\param{bool }{fixedWidthOnly = FALSE}}
	58
	59	Call \helpref{OnFacename}{wxfontenumeratoronfacename} for each font which
	60	supports given encoding (only if it is not wxFONTENCODING\_SYSTEM) and is of
	61	fixed width (if {\it fixedWidthOnly} is TRUE).
	62
	63	Calling this function with default arguments will result in enumerating all
	64	fonts available on the system.

	67
	68	\func{virtual bool}{EnumerateEncodings}{\param{const wxString\& }{font = ""}}
	69
	70	Call \helpref{OnFontEncoding}{wxfontenumeratoronfontencoding} for each
	71	encoding supported by the given font - or for each encoding supported by at
	72	least some font if {\it font} is not specified.

	76
	77	\func{wxArrayString*}{GetEncodings}{\void}
	78
	79	Return array of strings containing all encodings found by
	80	\helpref{EnumerateEncodings}{wxfontenumeratorenumerateencodings}. This is convenience function. It is
	81	based on default implementation of \helpref{OnFontEncoding}{wxfontenumeratoronfontencoding} so don't expect
	82	it to work if you overwrite that method.
	83
	84	\membersection{wxFontEnumerator::GetFacenames}\label{wxfontenumeratorgetfacenames}
	85
	86	\func{wxArrayString*}{GetFacenames}{\void}
	87
	88	Return array of strings containing all facenames found by
	89	\helpref{EnumerateFacenames}{wxfontenumeratorenumeratefacenames}. This is convenience function. It is
	90	based on default implementation of \helpref{OnFacename}{wxfontenumeratoronfacename} so don't expect
	91	it to work if you overwrite that method.

	95
	96	\func{virtual bool}{OnFacename}{\param{const wxString\& }{font}}
	97
	98	Called by \helpref{EnumerateFacenames}{wxfontenumeratorenumeratefacenames} for
	99	each match. Return TRUE to continue enumeration or FALSE to stop it.
