+\wxheading{Warning}
+
+As of wx 2.5.2, these functions are not thread-safe! (use static variables)
+
+{\it spec} may contain wildcards.
+
+{\it flags} may be wxDIR for restricting the query to directories, wxFILE for files or zero for either.
+
+For example:
+
+\begin{verbatim}

+\func{int}{wxParseCommonDialogsFilter}{\param{const wxString\& }{wildCard}, \param{wxArrayString\& }{descriptions}, \param{wxArrayString\& }{filters}}
+
+Parses the \arg{wildCard}, returning the number of filters.
+Returns 0 if none or if there's a problem.
+The arrays will contain an equal number of items found before the error.
+On platforms where native dialogs handle only one filter per entry,

+
+
+\membersection{::wxSplitPath}\label{wxsplitfunction}
+
+\func{void}{wxSplitPath}{\param{const char *}{ fullname}, \param{wxString *}{ path}, \param{wxString *}{ name}, \param{wxString *}{ ext}}
+
+{\bf NB:} This function is obsolete, please use
+\helpref{wxFileName::SplitPath}{wxfilenamesplitpath} instead.
+
+This function splits a full file name into components: the path (including possible disk/drive
+specification under Windows), the base name and the extension. Any of the output parameters
+({\it path}, {\it name} or {\it ext}) may be NULL if you are not interested in the value of
+a particular component.
+
+wxSplitPath() will correctly handle filenames with both DOS and Unix path separators under
+Windows, however it will not consider backslashes as path separators under Unix (where backslash
+is a valid character in a filename).
+
+On entry, {\it fullname} should be non-NULL (it may be empty though).
+
+On return, {\it path} contains the file path (without the trailing separator), {\it name}
+contains the file name and {\it ext} contains the file extension without leading dot. All
+three of them may be empty if the corresponding component is. The old contents of the
+strings pointed to by these parameters will be overwritten in any case (if the pointers
+are not NULL).
+

+\func{const char *}{wxGetTranslation}{\param{const char * }{str}}

+\func{const char *}{wxGetTranslation}{\param{const char * }{str}, \param{const char * }{strPlural}, \param{size\_t }{n}}
+
+This function returns the translation of string {\it str} in the current
+\helpref{locale}{wxlocale}. If the string is not found in any of the loaded
+message catalogs (see \helpref{internationalization overview}{internationalization}), the
+original string is returned. In debug build, an error message is logged -- this
+should help to find the strings which were not yet translated. As this function
+is used very often, an alternative (and also common in Unix world) syntax is
+provided: the \helpref{\_()}{underscore} macro is defined to do the same thing
+as wxGetTranslation.
+
+The second form is used when retrieving translation of string that has
+different singular and plural form in English or different plural forms in some
+other language. It takes two extra arguments: \arg{str}
+parameter must contain the singular form of the string to be converted.
+It is also used as the key for the search in the catalog.
+The \arg{strPlural} parameter is the plural form (in English).
+The parameter \arg{n} is used to determine the plural form. If no
+message catalog is found \arg{str} is returned if `n == 1',
+otherwise \arg{strPlural}.
+See \urlref{GNU gettext manual}{http://www.gnu.org/manual/gettext/html\_chapter/gettext\_10.html\#SEC150} for additional information on plural forms handling.

+
+\func{wxChar}{wxT}{\param{char }{ch}}

+\func{const wxChar *}{wxT}{\param{const char *}{s}}
+
+wxT() is a macro which can be used with character and string literals (in other
+words, {\tt 'x'} or {\tt "foo"}) to automatically convert them to Unicode in
+Unicode build configuration. Please see the
+\helpref{Unicode overview}{unicode} for more information.
+
+This macro is simply returns the value passed to it without changes in ASCII
+build. In fact, its definition is:
+\begin{verbatim}
+#ifdef UNICODE
+#define wxT(x) L ## x
+#else // !Unicode
+#define wxT(x) x
+#endif
+\end{verbatim}
+
+
+\membersection{wxTRANSLATE}\label{wxtranslate}
+
+\func{const wxChar *}{wxTRANSLATE}{\param{const char *}{s}}
+
+This macro doesn't do anything in the program code -- it simply expands to the
+value of its argument (except in Unicode build where it is equivalent to
+\helpref{wxT}{wxt} which makes it unnecessary to use both wxTRANSLATE and wxT
+with the same string which would be really unreadable).
+
+However it does have a purpose and it is to mark the literal strings for the
+extraction into the message catalog created by {\tt xgettext} program. Usually
+this is achieved using \helpref{\_()}{underscore} but that macro not only marks
+the string for extraction but also expands into a
+\helpref{wxGetTranslation}{wxgettranslation} function call which means that it
+cannot be used in some situations, notably for static array
+initialization.
+
+Here is an example which should make it more clear: suppose that you have a
+static array of strings containing the weekday names and which have to be
+translated (note that it is a bad example, really, as
+\helpref{wxDateTime}{wxdatetime} already can be used to get the localized week
+day names already). If you write
+
+\begin{verbatim}
+static const wxChar * const weekdays[] = { _("Mon"), ..., _("Sun") };
+...
+// use weekdays[n] as usual
+\end{verbatim}
+
+the code wouldn't compile because the function calls are forbidden in the array
+initializer. So instead you should do
+
+\begin{verbatim}
+static const wxChar * const weekdays[] = { wxTRANSLATE("Mon"), ..., wxTRANSLATE("Sun") };
+...
+// use wxGetTranslation(weekdays[n])
+\end{verbatim}
+
+here.
+
+Note that although the code {\bf would} compile if you simply omit
+wxTRANSLATE() in the above, it wouldn't work as expected because there would be
+no translations for the weekday names in the program message catalog and
+wxGetTranslation wouldn't find them.

+
+\func{const wxChar *}{\_}{\param{const char *}{s}}
+
+This macro expands into a call to \helpref{wxGetTranslation}{wxgettranslation}
+function, so it marks the message for the extraction by {\tt xgettext} just as
+\helpref{wxTRANSLATE}{wxtranslate} does, but also returns the translation of
+the string for the current locale during execution.
+
+Don't confuse this macro with \helpref{\_T()}{underscoret}!

+\func{const wxChar *}{\_T}{\param{const wxChar }{ch}}
+
+This macro is exactly the same as \helpref{wxT}{wxt} and is defined in
+wxWidgets simply because it may be more intuitive for Windows programmers as
+the standard Win32 headers also define it (as well as yet another name for the
+same macro which is {\tt \_TEXT()}).
+
+Don't confuse this macro with \helpref{\_()}{underscore}!

+\section{Dialog functions}\label{dialogfunctions}
+
+Below are a number of convenience functions for getting input from the
+user or displaying messages. Note that in these functions the last three
+parameters are optional. However, it is recommended to pass a parent frame
+parameter, or (in MS Windows or Motif) the wrong window frame may be brought to
+the front when the dialog box is popped up.
+
+
+\membersection{::wxBeginBusyCursor}\label{wxbeginbusycursor}
+
+\func{void}{wxBeginBusyCursor}{\param{wxCursor *}{cursor = wxHOURGLASS\_CURSOR}}
+
+Changes the cursor to the given cursor for all windows in the application.
+Use \helpref{wxEndBusyCursor}{wxendbusycursor} to revert the cursor back
+to its previous state. These two calls can be nested, and a counter
+ensures that only the outer calls take effect.
+
+See also \helpref{wxIsBusy}{wxisbusy}, \helpref{wxBusyCursor}{wxbusycursor}.

+This function creates a \helpref{wxTipProvider}{wxtipprovider} which may be
+used with \helpref{wxShowTip}{wxshowtip}.
+
+\docparam{filename}{The name of the file containing the tips, one per line}

+ \param{wxWindow *}{parent = NULL}}
+
+Pops up a directory selector dialog. The arguments have the same meaning as
+those of wxDirDialog::wxDirDialog(). The message is displayed at the top,
+and the default\_path, if specified, is set as the initial selection.
+
+The application must check for an empty return value (if the user pressed
+Cancel). For example:
+
+\begin{verbatim}
+const wxString& dir = wxDirSelector("Choose a folder");
+if ( !dir.empty() )
+{
+ ...
+}

+ \param{const wxString\& }{wildcard = ``*.*''}, \param{int }{flags = 0}, \param{wxWindow *}{parent = ""},\\
+ \param{int}{ x = -1}, \param{int}{ y = -1}}
+
+Pops up a file selector box. In Windows, this is the common file selector
+dialog. In X, this is a file selector box with the same functionality.
+The path and filename are distinct elements of a full file pathname.
+If path is empty, the current directory will be used. If filename is empty,
+no default filename will be supplied. The wildcard determines what files
+are displayed in the file selector, and file extension supplies a type
+extension for the required filename. Flags may be a combination of wxOPEN,
+wxSAVE, wxOVERWRITE\_PROMPT, wxFILE\_MUST\_EXIST, wxMULTIPLE or 0.
+
+Both the Unix and Windows versions implement a wildcard filter. Typing a
+filename containing wildcards (*, ?) in the filename text item, and
+clicking on Ok, will result in only those files matching the pattern being
+displayed.
+
+The wildcard may be a specification for multiple types of file
+with a description for each, such as:
+
+\begin{verbatim}
+ "BMP files (*.bmp)|*.bmp|GIF files (*.gif)|*.gif"
+\end{verbatim}
+
+The application must check for an empty return value (the user pressed
+Cancel). For example:
+
+\begin{verbatim}
+wxString filename = wxFileSelector("Choose a file to open");
+if ( !filename.empty() )
+{
+ // work with the file
+ ...
+}
+//else: cancelled by user
