+Searches the given file in all paths stored in this class.
+The first path which concatenated to the given string points to an existing
+file (see \helpref{wxFileExists}{wxfileexists}) is returned.

+If the file wasn't found in any of the stored paths, an empty string is returned.

+The given string must be a file name, eventually with a path prefix (if the path
+prefix is absolute, only its name will be searched); i.e. it must not end with
+a directory separator (see \helpref{wxFileName::GetPathSeparator}{wxfilenamegetpathseparator})

+The returned path may be relative to the current working directory.
+Note in fact that wxPathList can be used to store both relative and absolute paths so that

+(see \helpref{wxGetCwd}{wxgetcwd} and \helpref{wxSetWorkingDirectory}{wxsetworkingdirectory})
+may affect the value returned by this function!
