20 | // wxIniConfig is a wxConfig implementation which uses MS Windows INI files to | |
21 | // store the data. Because INI files don't really support arbitrary nesting of | |
22 | // groups, we do the following: | |
23 | // (1) in win.ini file we store all entries in the [vendor] section and | |
24 | // the value group1/group2/key is mapped to the value group1_group2_key | |
25 | // in this section, i.e. all path separators are replaced with underscore | |
26 | // (2) in appname.ini file we map group1/group2/group3/key to the entry | |
27 | // group2_group3_key in [group1] | |
28 | // | |
29 | // Of course, it might lead to indesirable results if '_' is also used in key | |
30 | // names (i.e. group/key is the same as group_key) and also GetPath() result | |
31 | // may be not what you would expect it to be. | |
32 | // | |
33 | // Another limitation: the keys and section names are never case-sensitive | |
34 | // which might differ from wxFileConfig it it was compiled with | |
35 | // wxCONFIG_CASE_SENSITIVE option. | |
36 | // ---------------------------------------------------------------------------- | |
37 | ||
38 | // for this class, "local" file is the file appname.ini and the global file | |
39 | // is the [vendor] subsection of win.ini (default for "vendor" is to be the | |
40 | // same as appname). The file name (strAppName parameter) may, in fact, | |
41 | // contain the full path to the file. If it doesn't, the file is searched for | |
42 | // in the Windows directory. | |
