1 \section{\class{wxConfigBase
}}\label{wxconfigbase
}
3 wxConfigBase class defines the basic interface of all config classes. It can
4 not be used by itself (it's an abstract base class) and you'll always use one
5 of its derivations: wxIniConfig, wxFileConfig, wxRegConfig or any other.
7 However, usually you don't even need to know the precise nature of the class
8 you're working with but you would just use the wxConfigBase methods. This
9 allows you to write the same code regardless of whether you're working with
10 the registry under Win32 or text-based config files under Unix (or even
11 Windows
3.1 .INI files if you're really unlucky). To make writing the portable
12 code even easier, wxWindows provides a typedef wxConfig
13 which is mapped onto the native wxConfigBase implementation on the given
14 platform: i.e. wxRegConfig under Win32, wxIniConfig under Win16 and
15 wxFileConfig otherwise.
17 See
\helpref{config overview
}{wxconfigoverview
} for the descriptions of all
18 features of this class.

26 <wx/config.h> (to let wxWindows choose a wxConfig class for your platform)\\
27 <wx/confbase.h> (base config class)\\
28 <wx/fileconf.h> (wxFileconfig class)\\
29 <wx/msw/regconf.h> (wxRegConfig class)\\
30 <wx/msw/iniconf.h> (wxIniConfig class)
34 Here is how you would typically use this class:
37 // using wxConfig instead of writing wxFileConfig or wxRegConfig enhances
38 // portability of the code
39 wxConfig *config = new wxConfig("MyAppName");
42 if ( config->Read("LastPrompt", &str) )
{
43 // last prompt was found in the config file/registry and its value is now
51 // another example: using default values and the full path instead of just
52 // key name: if the key is not found , the value
17 is returned
53 long value = config->Read("/LastRun/CalculatedValues/MaxValue", -
1);
57 // at the end of the program we would save everything back
58 config->Write("LastPrompt", str);
59 config->Write("/LastRun/CalculatedValues/MaxValue", value);
61 // the changes will be written back automatically
65 This basic example, of course, doesn't show all wxConfig features, such as
66 enumerating, testing for existence and deleting the entries and groups of
67 entries in the config file, its abilities to automatically store the default
68 values or expand the environment variables on the fly. However, the main idea
69 is that using this class is easy and that it should normally do what you
72 NB: in the documentation of this class, the words "config file" also mean
73 "registry hive" for wxRegConfig and, generally speaking, might mean any
74 physical storage where a wxConfigBase-derived class stores its data.

78 \membersection{Static functions
}
80 These functions deal with the "default" config object. Although its usage is
81 not at all mandatory it may be convenient to use a global config object
82 instead of creating and deleting the local config objects each time you need
83 one (especially because creating a wxFileConfig object might be a time
84 consuming operation). In this case, you may create this global config object
85 in the very start of the program and
{\it Set()
} it as the default. Then, from
86 anywhere in your program, you may access it using the
{\it Get()
} function. Of
87 course, you should delete it on the program termination (otherwise, not only a
88 memory leak will result, but even more importantly the changes won't be
91 As it happens, you may even further simplify the procedure described above:
92 you may forget about calling
{\it Set()
}. When
{\it Get()
} is called and there
93 is no current object, it will create one using
{\it Create()
} function. To
94 disable this behaviour
{\it DontCreateOnDemand()
} is provided.

106 \membersection{Path management
}
108 As explained in
\helpref{config overview
}{wxconfigoverview
}, the config classes
109 support a file system-like hierarchy of keys (files) and groups (directories).
110 As in the file system case, to specify a key in the config class you must use
111 a path to it. Config classes also support the notion of the current group,
112 which makes it possible to use the relative paths. To clarify all this, here
113 is an example (it's only for the sake of demonstration, it doesn't do anything
117 wxConfig *config = new wxConfig("FooBarApp");
119 // right now the current path is '/'
120 conf->Write("RootEntry",
1);
122 // go to some other place: if the group(s) don't exist, they will be created
123 conf->SetPath("/Group/Subgroup");
125 // create an entry in subgroup
126 conf->Write("SubgroupEntry",
3);
128 // '..' is understood
129 conf->Write("../GroupEntry",
2);
132 wxASSERT( conf->Read("Subgroup/SubgroupEntry",
0l) ==
3 );
134 // use absolute path: it's allowed, too
135 wxASSERT( conf->Read("/RootEntry",
0l) ==
1 );
138 {\it Warning
}: it's probably a good idea to always restore the path to its
139 old value on function exit:
142 void foo(wxConfigBase *config)
144 wxString strOldPath = config->GetPath();
146 config->SetPath("/Foo/Data");
149 config->SetPath(strOldPath);
153 because otherwise the assert in the following example will surely fail
154 (we suppose here that
{\it foo()
} function is the same as above except that it
155 doesn't save and restore the path):
158 void bar(wxConfigBase *config)
160 config->Write("Test",
17);
164 // we're reading "/Foo/Data/Test" here! -
1 will probably be returned...
165 wxASSERT( config->Read("Test", -
1) ==
17 );
169 Finally, the path separator in wxConfigBase and derived classes is always '/',
170 regardless of the platform (i.e. it's
{\bf not
} '$
\backslash\backslash$' under Windows).

}
175 \membersection{Enumeration
}
177 The functions in this section allow to enumerate all entries and groups in the
178 config file. All functions here return FALSE when there are no more items.
180 You must pass the same index to GetNext and GetFirst (don't modify it).
181 Please note that it's
{\bf not
} the index of the current item (you will have
182 some great surprizes with wxRegConfig if you assume this) and you shouldn't
183 even look at it: it's just a "cookie" which stores the state of the
184 enumeration. It can't be stored inside the class because it would prevent you
185 from running several enumerations simultaneously, that's why you must pass it
188 Having said all this, enumerating the config entries/groups is very simple:
191 wxArrayString aNames;
193 // enumeration variables
197 // first enum all entries
198 bool bCont = config->GetFirstEntry(str, dummy);
202 bCont = GetConfig()->GetNextEntry(str, dummy);
205 ... we have all entry names in aNames...
208 bCont = GetConfig()->GetFirstGroup(str, dummy);
212 bCont = GetConfig()->GetNextGroup(str, dummy);
215 ... we have all group (and entry) names in aNames...
219 There are also functions to get the number of entries/subgroups without
220 actually enumerating them, but you will probably never need them.

242 \membersection{Key access
}
244 These function are the core of wxConfigBase class: they allow you to read and
245 write config file data. All
{\it Read
} function take a default value which
246 will be returned if the specified key is not found in the config file.
248 Currently, only two types of data are supported: string and long (but it might
249 change in the near future). To work with other types: for
{\it int
} or
{\it
250 bool
} you can work with function taking/returning
{\it long
} and just use the
251 casts. Better yet, just use
{\it long
} for all variables which you're going to
252 save in the config file: chances are that
\verb$sizeof(bool) == sizeof(int) == sizeof(long)$ anyhow on your system. For
{\it float
},
{\it double
} and, in
253 general, any other type you'd have to translate them to/from string
254 representation and use string functions.
256 Try not to read long values into string variables and vice versa: although it
257 just might work with wxFileConfig, you will get a system error with
258 wxRegConfig because in the Windows registry the different types of entries are
261 Final remark: the
{\it szKey
} parameter for all these functions can contain an
262 arbitrary path (either relative or absolute), not just the key name.

268 \membersection{Rename entries/groups
}
270 The functions in this section allow to rename entries or subgroups of the
271 current group. They will return FALSE on error. typically because either the
272 entry/group with the original name doesn't exist, because the entry/group with
273 the new name already exists or because the function is not supported in this
274 wxConfig implementation.

279 \membersection{Delete entries/groups
}
281 The functions in this section delete entries and/or groups of entries from the
282 config file.
{\it DeleteAll()
} is especially useful if you want to erase all
283 traces of your program presence: for example, when you uninstall it.

289 \membersection{Options
}
291 Some aspects of wxConfigBase behaviour can be changed during run-time. The
292 first of them is the expansion of environment variables in the string values
293 read from the config file: for example, if you have the following in your
297 # config file for my program
298 UserData = $HOME/data
300 # the following syntax is valud only under Windows
301 UserData =
%windir%\\data.dat
304 the call to
\verb$config->Read("UserData")$ will return something like
305 \verb$"/home/zeitlin/data"$ if you're lucky enough to run a Linux system ;-)
307 Although this feature is very useful, it may be annoying if you read a value
308 which containts '\$' or '\%' symbols (\% is used for environment variables
309 expansion under Windows) which are not used for environment variable
310 expansion. In this situation you may call SetExpandEnvVars(FALSE) just before
311 reading this value and SetExpandEnvVars(TRUE) just after. Another solution
312 would be to prefix the offending symbols with a backslash.
314 The following functions control this option:
