  Audacity: A Digital Audio Editor

  
  ControlToolbar.h
 
  Dominic Mazzoni
  Shane T. Mueller
 
  This class, which is a child of Toolbar, creates the
  window containing the tool selection (ibeam, envelope,
  move, zoom), the rewind/play/stop/record/ff buttons, and
  the volume control. The window can be embedded within a
  normal project window, or within a ToolbarFrame that is
  managed by a global ToolBarStub called
  gControlToolBarStub.

  All of the controls in this window were custom-written for
  Audacity - they are not native controls on any platform -
  however, it is intended that the images could be easily
  replaced to allow "skinning" or just customization to
  match the look and feel of each platform.
