13 This control allows the user to select a directory. The generic implementation is
14 a button which brings up a \helpref{wxDirDialog}{wxdirdialog} when clicked. Native implementation
15 may differ but this is usually a (small) widget which give access to the dir-chooser
16 dialog.
17 It is only available if \texttt{wxUSE\_DIRPICKERCTRL} is set to $1$ (the default).
