wx.FontEnumerator¶wx.FontEnumerator enumerates either all available fonts on the system or only the ones with given attributes - either only fixed-width (suited for use in programs such as terminal emulators and the like) or the fonts available in the given encoding).
To do this, you just have to call one of EnumerateXXX() functions - either wx.FontEnumerator.EnumerateFacenames or wx.FontEnumerator.EnumerateEncodings and the corresponding callback ( wx.FontEnumerator.OnFacename or wx.FontEnumerator.OnFontEncoding ) will be called repeatedly until either all fonts satisfying the specified criteria are exhausted or the callback returns False.
Virtual functions to override¶Either OnFacename or OnFontEncoding should be overridden depending on whether you plan to call EnumerateFacenames or EnumerateEncodings. Of course, if you call both of them, you should override both functions.

Class API¶
Inheritance diagram for class FontEnumerator:
wx.FontEnumerator(object)¶Possible constructors:
FontEnumerator()
FontEnumerator enumerates either all available fonts on the system or only the ones with given attributes - either only fixed-width (suited for use in programs such as terminal emulators and the like) or the fonts available in the given encoding).
__init__(self)¶EnumerateEncodings(self, font="")¶Call OnFontEncoding for each encoding supported by the given font - or for each encoding supported by at least some font if font is not specified.
font (string) –
bool
EnumerateFacenames(self, encoding=FONTENCODING_SYSTEM, fixedWidthOnly=False)¶Call OnFacename for each font which supports given encoding (only if it is not FONTENCODING_SYSTEM ) and is of fixed width (if fixedWidthOnly is True).
Calling this function with default arguments will result in enumerating all fonts available on the system.
encoding (FontEncoding) –
fixedWidthOnly (bool) –
bool
GetEncodings(facename="")¶Return array of strings containing all encodings found by EnumerateEncodings .
facename (string) –
list of strings
GetFacenames(encoding=FONTENCODING_SYSTEM, fixedWidthOnly=False)¶Return array of strings containing all facenames found by EnumerateFacenames .
encoding (FontEncoding) –
fixedWidthOnly (bool) –
list of strings
InvalidateCache()¶Invalidate cache used by some of the methods of this class internally.
This method should be called if the list of the fonts available on the system changes, for whatever reason. In particular, it is called automatically by wx.Font.AddPrivateFont .
New in version 4.1/wxWidgets-3.1.1.
IsValidFacename(facename)¶Returns True if the given string is valid face name, i.e.
it’s the face name of an installed font and it can safely be used with wx.Font.SetFaceName .
facename (string) –
bool
OnFacename(self, font)¶Called by EnumerateFacenames for each match.
Return True to continue enumeration or False to stop it.
font (string) –
bool
OnFontEncoding(self, font, encoding)¶Called by EnumerateEncodings for each match.
Return True to continue enumeration or False to stop it.
font (string) –
encoding (string) –
bool
