  8. The Dialog class is a subclass of <a href="Window.html">Window</a> designed
    9. 

  9. for use as a dialog box. It provides facilities for defining default and
    10. 

  10. cancel buttons that are activated by keyboard equivalents.<br>
    11. 

  11. <br>
    12. 

  12. A Dialog differs from a Window in having a default style of <tt>'nonmodal_dialog'</tt>,
    13. 

  13. and by default (if possible on the platform) not being closable, zoomable
    14. 

  14. or resizable. These options can be overridden in the constructor call. <br>
    15. 

  15. <br>
    16. 

  16. On platforms which display a menu bar at the top of each window, a Dialog
    17. 

  17. does not normally have a menu bar. Enabled menu items are still available by their
    18. 

  18. keyboard equivalents while the Dialog is active, however.<br>
