|

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

// in the Windows directory.
