The format of the returned string is "(*.ext1;*.ext2)|*.ext1;*.ext2".
|

It is usually a good idea to prepend a description before passing the result to the dialog.

Example:

\begin{verbatim}

wxFileDialog FileDlg( this, "Choose Image", ::wxGetWorkingDirectory(), "", _("Image Files ") + wxImage::GetImageExtWildcard(), wxOPEN );
