  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}

  95 \membersection{wxFileDialog::GetFilenames}\label{wxfiledialoggetfilenames}
  96
  97 \constfunc{void}{GetFilenames}{\param{wxArrayString\& }{filenames}}
