\wxheading{Window styles}

\begin{twocollist}\itemsep=0pt
\twocolitem{\windowstyle{wxDD\_DEFAULT\_STYLE}}{Equivalent to a combination of wxDEFAULT\_DIALOG\_STYLE and wxRESIZE\_BORDER (the last one is not used under wxWinCE).}
\twocolitem{\windowstyle{wxDD\_DIR\_MUST\_EXIST}}{The dialog will allow the user to choose only an existing folder. When this style is not given, a "Create new directory" button is added to the dialog (on Windows) or some other way is provided to the user to type the name of a new folder.}
\twocolitem{\windowstyle{wxDD\_CHANGE\_DIR}}{Change the current working directory to the directory chosen by the user.}
\end{twocollist}

{\bf NB:} on Windows the new directory button is only available with recent versions of the common dialogs.
