  Audacity: A Digital Audio Editor

  PrefsPanel.h

  Joshua Haberman

  The interface works like this: Each panel in the preferences dialog
  must derive from PrefsPanel. You must override Apply() with code
  to validate fields (returning false if any are bad), updating the
  global preferences object gPrefs, and instructing the applicable parts
  of the program to re-read the preference options.

  To actually add a the new panel, edit the PrefsDialog constructor
  to append the panel to its list of panels.
