10 | ||
11 | wxFileConfig implements wxConfigBase interface for | |
12 | storing and retrieving configuration information using plain text files. The | |
13 | files have a simple format reminiscent of Windows INI files with lines of the | |
14 | form @c "key = value" defining the keys and lines of special form | |
15 | @c "[group]" indicating the start of each group. | |
16 | ||
17 | This class is used by default for wxConfig on Unix platforms but may also be | |
18 | used explicitly if you want to use files and not the registry even under | |
19 | Windows. | |

32 | If @a localFilename and/or @a globalFilename are explicitly specified, | |
33 | they are used as the names of the user and system-wide configuration | |
34 | files (the latter is only read by the program while the former is read | |
35 | from and written to). Otherwise the behaviour depends on @a style | |
36 | parameter. If it includes ::wxCONFIG_USE_LOCAL_FILE, then the local | |
37 | file name is constructed from the information in @a appName and @a | |
38 | vendorName arguments in a system-dependent way. If | |
39 | ::wxCONFIG_USE_GLOBAL_FILE is not specified at all (and @a | |
40 | globalFilename is empty) then the system-wide file is not used at all. | |
41 | Otherwise its name and path are also constructed in the way appropriate | |
42 | for the current platform from the application and vendor names. | |
