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. | |

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. | |

75 | \membersection{wxFontEnumerator::GetEncodings}\label{wxfontenumeratorgetencodings} | |
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. | |
