+\twocolitem{\windowstyle{wxFD\_DEFAULT\_STYLE}}{Equivalent to wxFD\_OPEN.}
+\twocolitem{\windowstyle{wxFD\_OPEN}}{This is an open dialog; usually this means that the default button's label of the dialog is "Open". Cannot be combined with wxFD\_SAVE.}
+\twocolitem{\windowstyle{wxFD\_SAVE}}{This is a save dialog; usually this means that the default button's label of the dialog is "Save". Cannot be combined with wxFD\_OPEN.}
+\twocolitem{{\windowstyle wxFD\_OVERWRITE\_PROMPT}}{For save dialog only: prompt for a confirmation if a file will be overwritten.}
+\twocolitem{{\windowstyle wxFD\_FILE\_MUST\_EXIST}}{For open dialog only: the user may only select files that actually exist.}
+\twocolitem{{\windowstyle wxFD\_MULTIPLE}}{For open dialog only: allows selecting multiple files.}
+\twocolitem{{\windowstyle wxFD\_CHANGE\_DIR}}{Change the current working directory to the directory where the file(s) chosen by the user are.}
+\twocolitem{{\windowstyle wxFD\_PREVIEW}}{Show the preview of the selected files (currently only supported by wxGTK using GTK+ 2.4 or later).}

+
+{\bf NB:} Previous versions of wxWidgets used {\tt wxFD\_CHANGE\_DIR} by default
+under MS Windows which allowed the program to simply remember the last
+directory where user selected the files to open/save. This (desired)
+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.
