// FileSelector is a FileChooser (InterViews class) which contains a
// QueryValue as a member.  The QueryValue initially contains the directory
// to being the file search, and ends up containing the name of the file to be
// opened.  A FileSelector instance is a member of the FileDialog class (see
// dialog.h).
