+Pops up a file selector box. In Windows and GTK2.4+, this is the common
+file selector dialog. In X, this is a file selector box with somewhat less
+functionality. The path and filename are distinct elements of a full file pathname.
If path is ``", the current directory will be used. If filename is ``",
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, wxHIDE\_READONLY, wxFILE\_MUST\_EXIST, wxMULTIPLE or 0.
+wxSAVE, wxOVERWRITE\_PROMPT, wxHIDE\_READONLY, wxFILE\_MUST\_EXIST,
+wxMULTIPLE, wxCHANGE\_DIR or 0.
Both the X and Windows versions implement a wildcard filter. Typing a
filename containing wildcards (*, ?) in the filename text item, and
types of file with a description for each, such as:
\begin{verbatim}
- "BMP files (*.bmp)|*.bmp|GIF files (*.gif)|*.gif"
+ "BMP and GIF files (*.bmp;*.gif)|*.bmp;*.gif|PNG files (*.png)|*.png"
\end{verbatim}
+It must be noted that wildcard support in the native Motif file
+dialog is quite limited: only one alternative is supported,
+and it is displayed without the descriptive test; ``BMP files (*.bmp)|*.bmp''
+is displayed as ``*.bmp'', and both
+``BMP files (*.bmp)|*.bmp|GIF files (*.gif)|*.gif'' and
+``Image files|*.bmp;*.gif'' are errors.

+{\bf NB:} Previous versions of wxWidgets used {\tt wxCHANGE\_DIR} by default

+functionality must be implemented in the program itself now (manually remember
+the last path used and pass it to the dialog the next time it is called) or
+by using this flag.
