22 Pops up a file selector box. In Windows, this is the common file selector
23 dialog. In X, this is a file selector box with somewhat less functionality.
24 The path and filename are distinct elements of a full file pathname.
25 If path is ``", the current directory will be used. If filename is ``",
26 no default filename will be supplied. The wildcard determines what files
27 are displayed in the file selector, and file extension supplies a type
28 extension for the required filename. Flags may be a combination of wxOPEN,
29 wxSAVE, wxOVERWRITE\_PROMPT, wxHIDE\_READONLY, wxFILE\_MUST\_EXIST, wxMULTIPLE or 0.
30
31 Both the X and Windows versions implement a wildcard filter. Typing a
32 filename containing wildcards (*, ?) in the filename text item, and
33 clicking on Ok, will result in only those files matching the pattern being
34 displayed. The wildcard may be a specification for multiple
35 types of file with a description for each, such as:
36
37 \begin{verbatim}
38 "BMP files (*.bmp)|*.bmp|GIF files (*.gif)|*.gif"
39 \end{verbatim}

91 \constfunc{wxString}{GetFilename}{\void}
92
93 Returns the default filename.
94
95 \membersection{wxFileDialog::GetFilenames}\label{wxfiledialoggetfilenames}
96
97 \constfunc{void}{GetFilenames}{\param{wxArrayString\& }{filenames}}
