| 16 | // wxIniConfig is a wxConfig implementation which uses MS Windows INI files to |
| 17 | // store the data. Because INI files don't really support arbitrary nesting of |
| 18 | // groups, we do the following: |
| 19 | // (1) in win.ini file we store all entries in the [vendor] section and |
| 20 | // the value group1/group2/key is mapped to the value group1_group2_key |
| 21 | // in this section, i.e. all path separators are replaced with underscore |
| 22 | // (2) in appname.ini file we map group1/group2/group3/key to the entry |
| 23 | // group2_group3_key in [group1] |
| 24 | // |
| 25 | // Of course, it might lead to indesirable results if '_' is also used in key |
| 26 | // names (i.e. group/key is the same as group_key) and also GetPath() result |
| 27 | // may be not what you would expect it to be. |
| 28 | // |
| 29 | // Another limitation: the keys and section names are never case-sensitive |
| 30 | // which might differ from wxFileConfig it it was compiled with |
| 31 | // wxCONFIG_CASE_SENSITIVE option. |
| 32 | // ---------------------------------------------------------------------------- |
| 33 | |
| 34 | // for this class, "local" file is the file appname.ini and the global file |
| 35 | // is the [vendor] subsection of win.ini (default for "vendor" is to be the |
| 36 | // same as appname). The file name (strAppName parameter) may, in fact, |
| 37 | // contain the full path to the file. If it doesn't, the file is searched for |
| 38 | // in the Windows directory. |
