7 | ||
8 | This class is the base class of a hierarchy of classes capable of converting | |
9 | text strings between multibyte (SBCS or DBCS) encodings and Unicode. It is itself | |
10 | a wrapper around the standard libc mbstowcs() and wcstombs() routines, and has | |
11 | one predefined instance, {\bf wxConvLibc}. | |
12 | ||
13 | \wxheading{Derived from} | |

31 | ||
32 | \func{}{wxMBConv}{\void} | |
33 | ||
34 | Constructor. | |
35 | ||
36 | \membersection{wxMBConv::MB2WC}\label{wxmbconvmb2wc} | |
37 | ||
38 | \constfunc{virtual size\_t}{MB2WC}{\param{wchar\_t* }{buf}, \param{const char* }{psz}, \param{size\_t }{n}} | |
39 | ||
40 | Converts from a string {\it psz} in multibyte encoding to Unicode putting the | |
41 | output into the buffer {\it buf} of the size {\it n} (in wide characters, not | |
42 | bytes). If {\it buf} is {\tt NULL}, nothing is written to it but the length of | |
43 | the string which would result from the conversion is calculated and returned. | |
44 | Note that this is the length and not size, i.e. the returned value does | |
45 | {\bf not} include the trailing NUL. But when the function is called with a | |
46 | non-{\tt NULL} buffer, the {\it n} parameter should be the size of the buffer | |
47 | and so it {\bf should} take into account the trailing NUL. | |
48 | ||
49 | \wxheading{Parameters} | |
50 | ||
51 | \docparam{buf}{the output buffer, may be {\tt NULL} if the caller is only | |
52 | interested in the length of the resulting string} | |
53 | ||
54 | \docparam{psz}{the {\tt NUL}-terminated input string, cannot be {\tt NULL}} | |
55 | ||
56 | \docparam{n}{the size of the output buffer, ignored if {\it buf} is {\tt NULL}} | |
57 | ||
58 | \wxheading{Return value} | |
59 | ||
60 | The length of the converted string. | |
61 | ||
62 | \membersection{wxMBConv::WC2MB}\label{wxmbconvwc2mb} | |
63 | ||
64 | \constfunc{virtual size\_t}{WC2MB}{\param{char* }{buf}, \param{const wchar\_t* }{psz}, \param{size\_t }{n}} | |
65 | ||
66 | Converts from Unicode to multibyte encoding. The semantics of this function | |
67 | (including the return value meaning) is the same as for | |
68 | \helpref{MB2WC}{wxmbconvmb2wc}. | |
69 | ||
70 | Notice that when the function is called with a non-{\tt NULL} buffer, the | |
71 | {\it n} parameter should be the size of the buffer and so it {\bf should} take | |
72 | into account the trailing NUL, which might take two or four bytes for some | |
73 | encodings (UTF-16 and UTF-32). | |
74 | ||
75 | \membersection{wxMBConv::cMB2WC}\label{wxmbconvcmb2wc} | |
76 | ||
77 | \constfunc{const wxWCharBuffer}{cMB2WC}{\param{const char* }{psz}} | |
78 | ||
79 | Converts from multibyte encoding to Unicode by calling MB2WC, | |
80 | allocating a temporary wxWCharBuffer to hold the result. | |
81 | ||
82 | \membersection{wxMBConv::cWC2MB}\label{wxmbconvcwc2mb} | |
83 | ||
84 | \constfunc{const wxCharBuffer}{cWC2MB}{\param{const wchar\_t* }{psz}} | |
85 | ||
86 | Converts from Unicode to multibyte encoding by calling WC2MB, | |
87 | allocating a temporary wxCharBuffer to hold the result. | |
88 | ||
89 | \membersection{wxMBConv::cMB2WX}\label{wxmbconvcmb2wx} | |
90 | ||
91 | \constfunc{const char*}{cMB2WX}{\param{const char* }{psz}} | |
92 | ||
93 | \constfunc{const wxWCharBuffer}{cMB2WX}{\param{const char* }{psz}} | |
94 | ||
95 | Converts from multibyte encoding to the current wxChar type | |
96 | (which depends on whether wxUSE\_UNICODE is set to 1). If wxChar is char, | |
97 | it returns the parameter unaltered. If wxChar is wchar\_t, it returns the | |
98 | result in a wxWCharBuffer. The macro wxMB2WXbuf is defined as the correct | |
99 | return type (without const). | |

103 | \constfunc{const char*}{cWX2MB}{\param{const wxChar* }{psz}} | |
104 | ||
105 | \constfunc{const wxCharBuffer}{cWX2MB}{\param{const wxChar* }{psz}} | |
106 | ||
107 | Converts from the current wxChar type to multibyte encoding. If wxChar is char, | |
108 | it returns the parameter unaltered. If wxChar is wchar\_t, it returns the | |
109 | result in a wxCharBuffer. The macro wxWX2MBbuf is defined as the correct | |
110 | return type (without const). | |
111 | ||
112 | \membersection{wxMBConv::cWC2WX}\label{wxmbconvcwc2wx} | |

115 | ||
116 | \constfunc{const wxCharBuffer}{cWC2WX}{\param{const wchar\_t* }{psz}} | |
117 | ||
118 | Converts from Unicode to the current wxChar type. If wxChar is wchar\_t, | |
119 | it returns the parameter unaltered. If wxChar is char, it returns the | |
120 | result in a wxCharBuffer. The macro wxWC2WXbuf is defined as the correct | |
121 | return type (without const). | |
122 | ||
123 | \membersection{wxMBConv::cWX2WC}\label{wxmbconvcwx2wc} | |

126 | ||
127 | \constfunc{const wxWCharBuffer}{cWX2WC}{\param{const wxChar* }{psz}} | |
128 | ||
129 | Converts from the current wxChar type to Unicode. If wxChar is wchar\_t, | |
130 | it returns the parameter unaltered. If wxChar is char, it returns the | |
131 | result in a wxWCharBuffer. The macro wxWX2WCbuf is defined as the correct | |
132 | return type (without const). | |
