 /*!
   \class FileSelector fileselector.h
   \brief The FileSelector widget allows the user to select DocLnk objects.
 
   This class presents a file selection dialog to the user. This widget
   is usually the first widget seen in a \link docwidget.html
   document-oriented application\endlink. The developer will most often
   create this widget in combination with a <a
   href="../qt/qwidgetstack.html"> QWidgetStack</a> and the appropriate
   editor and/or viewer widget for their application. This widget
   should be shown first and the user can the select which document
   they wish to operate on. Please refer to the implementation of
   texteditor for an example of how to tie these classes together.
 
   Use setNewVisible() depending on whether the application can be used
   to create new files or not. Use setCloseVisible() depending on
   whether the user may leave the dialog without creating or selecting
   a document or not. The number of files in the view is available from
   fileCount(). To force the view to be updated call reread().
 
   If the user presses the 'New Document' button the newSelected()
   signal is emitted. If the user selects an existing file the
   fileSelected() signal is emitted. The selected file's \link
   doclnk.html DocLnk\endlink is available from the selected()
   function. If the file selector is no longer necessary the closeMe()
   signal is emitted.

   Constructs a FileSelector with mime filter \a f.
   The standard Qt \a parent and \a name parameters are passed to the

   If \a newVisible is TRUE, the widget has a button to allow the user
   the create "new" documents; this is useful for applications that can
   create and edit documents but not suitable for applications that
   only provide viewing.
