   5  * A fileselector is a widget that allows a user to navigate through a tree
   6  * of files.  It contains buttons for Home(~) and Up(..) as well as cancel/ok
   7  * buttons to confirm/cancel a selection.  This widget is currently very much
   8  * in progress.
   9
  10  * Signals that you can add callbacks for are:
  11  *
  12  * "selected" - the user clicks on a file
  13  * "directory,open" - the list is populated with a new content. event_info is a directory.
  14  * "done" - the user clicks on the ok or cancel button
