\wxheading{Remarks}

Pops up a file selector box. In Windows, 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.

Both the X and Windows versions implement a wildcard filter. Typing a
filename containing wildcards (*, ?) in the filename text item, and
clicking on Ok, will result in only those files matching the pattern being
displayed. The wildcard may be a specification for multiple
types of file with a description for each, such as:

\begin{verbatim}
 "BMP files (*.bmp)|*.bmp|GIF files (*.gif)|*.gif"
\end{verbatim}

\membersection{wxFileDialog::wxFileDialog}\label{wxfiledialogconstr}

\func{}{wxFileDialog}{\param{wxWindow* }{parent}, \param{const wxString\& }{message = "Choose a file"},\rtfsp
\param{const wxString\& }{defaultDir = ""}, \param{const wxString\& }{defaultFile = ``"},\rtfsp
\param{const wxString\& }{wildcard = ``*.*"}, \param{long }{style = 0}, \param{const wxPoint\& }{pos = wxDefaultPosition}}

Constructor. Use \helpref{wxFileDialog::ShowModal}{wxfiledialogshowmodal} to show the dialog.

\wxheading{Parameters}

\docparam{parent}{Parent window.}

\docparam{message}{Message to show on the dialog.}

\docparam{defaultDir}{The default directory, or the empty string.}

\docparam{defaultFile}{The default filename, or the empty string.}

\docparam{wildcard}{A wildcard, such as ``*.*" or ``BMP files (*.bmp)|*.bmp|GIF files (*.gif)|*.gif".}

\docparam{style}{A dialog style. A bitlist of:

\twocolwidtha{5cm}
\begin{twocollist}
\twocolitem{{\bf wxOPEN}}{This is an open dialog.}
\twocolitem{{\bf wxSAVE}}{This is a save dialog.}
\twocolitem{{\bf wxHIDE\_READONLY}}{Hide read-only files.}
\twocolitem{{\bf wxOVERWRITE\_PROMPT}}{For save dialog only: prompt for a confirmation if a file will be overwritten.}
\twocolitem{{\bf wxMULTIPLE}}{For open dialog only: allows selecting multiple files.}
\twocolitem{{\bf wxCHANGE\_DIR}}{Change the current working directory to the
directory where the file(s) chosen by the user are.}
\end{twocollist}%
}

\docparam{pos}{Dialog position. Not implemented.}

{\bf NB:} Previous versions of wxWindows used {\tt wxCHANGE\_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.

\membersection{wxFileDialog::\destruct{wxFileDialog}}

\func{}{\destruct{wxFileDialog}}{\void}

Destructor.

\membersection{wxFileDialog::GetDirectory}\label{wxfiledialoggetdirectory}

\constfunc{wxString}{GetDirectory}{\void}

Returns the default directory.

\membersection{wxFileDialog::GetFilename}\label{wxfiledialoggetfilename}

\constfunc{wxString}{GetFilename}{\void}

Returns the default filename.

\membersection{wxFileDialog::GetFilenames}\label{wxfiledialoggetfilenames}

\constfunc{void}{GetFilenames}{\param{wxArrayString\& }{filenames}}

Fills the array {\it filenames} with the names of the files chosen. This
function should only be used with the dialogs which have {\tt wxMULTIPLE} style,
use \helpref{GetFilename}{wxfiledialoggetfilename} for the others.

\membersection{wxFileDialog::GetFilterIndex}\label{wxfiledialoggetfilterindex}

\constfunc{int}{GetFilterIndex}{\void}

Returns the index into the list of filters supplied, optionally, in the wildcard parameter.
Before the dialog is shown, this is the index which will be used when the dialog is first displayed.
After the dialog is shown, this is the index selected by the user.

\membersection{wxFileDialog::GetMessage}\label{wxfiledialoggetmessage}

\constfunc{wxString}{GetMessage}{\void}

Returns the message that will be displayed on the dialog.

\membersection{wxFileDialog::GetPath}\label{wxfiledialoggetpath}

\constfunc{wxString}{GetPath}{\void}

Returns the full path (directory and filename) of the selected file.

\membersection{wxFileDialog::GetPaths}\label{wxfiledialoggetpaths}

\constfunc{void}{GetPaths}{\param{wxArrayString\& }{paths}}

Fills the array {\it paths} with the full paths of the files chosen. This
function should only be used with the dialogs which have {\tt wxMULTIPLE} style,
use \helpref{GetPath}{wxfiledialoggetpath} for the others.

\membersection{wxFileDialog::GetStyle}\label{wxfiledialoggetstyle}

\constfunc{long}{GetStyle}{\void}

Returns the dialog style.

\membersection{wxFileDialog::GetWildcard}\label{wxfiledialoggetwildcard}

\constfunc{wxString}{GetWildcard}{\void}

Returns the file dialog wildcard.

\membersection{wxFileDialog::SetDirectory}\label{wxfiledialogsetdirectory}

\func{void}{SetDirectory}{\param{const wxString\& }{directory}}

Sets the default directory.

\membersection{wxFileDialog::SetFilename}\label{wxfiledialogsetfilename}

\func{void}{SetFilename}{\param{const wxString\& }{setfilename}}

Sets the default filename.

\membersection{wxFileDialog::SetFilterIndex}\label{wxfiledialogsetfilterindex}

\func{void}{SetFilterIndex}{\param{int }{filterIndex}}

Sets the default filter index, starting from zero. Windows only.

\membersection{wxFileDialog::SetMessage}\label{wxfiledialogsetmessage}

\func{void}{SetMessage}{\param{const wxString\& }{message}}

Sets the message that will be displayed on the dialog.

\membersection{wxFileDialog::SetPath}\label{wxfiledialogsetpath}

\func{void}{SetPath}{\param{const wxString\& }{path}}

Sets the path (the combined directory and filename that will be returned when the dialog is dismissed).

\membersection{wxFileDialog::SetStyle}\label{wxfiledialogsetstyle}

\func{void}{SetStyle}{\param{long }{style}}

Sets the dialog style. See \helpref{wxFileDialog::wxFileDialog}{wxfiledialogconstr} for details.

\membersection{wxFileDialog::SetWildcard}\label{wxfiledialogsetwildcard}

\func{void}{SetWildcard}{\param{const wxString\& }{wildCard}}

Sets the wildcard, which can contain multiple file types, for example:

``BMP files (*.bmp)|*.bmp|GIF files (*.gif)|*.gif"

\membersection{wxFileDialog::ShowModal}\label{wxfiledialogshowmodal}

\func{int}{ShowModal}{\void}

Shows the dialog, returning wxID\_OK if the user pressed OK, and wxID\_CANCEL
otherwise.
