MGHGRDATAMATION__DEFINE

Class


  MGHgrDatamation

Purpose


  A container holding a graphics tree and a sequence of MGH_Command objects,
  to be managed and displayed by an animator window such as MGH_Datamator.

Properties



  The following properties (ie keywords to the Init, GetProperty & SetProperty
  methods) are supported
    CLONE (Get)
      This is a logical (integer) value that tells the animator whether the frames
      delivered by the animation's Get method are copies of the ones held
      in the container (CLONE=1) or the originals (CLONE=0). For an
      MGHgrDatamation, CLONE is 0.
    GRAPHICS_TREE (Init, Get, Set)
      This is a reference to an IDLgrView, IDLgrViewGroup or IDLgrScene
      object. The frames in the animation are rendered by executing commands
      which modify the graphics tree.
    MULTIPLE (Get)
      This is a logical (integer) value that tells users whether the animation
      supports the simultaneous display of multiple frames. For an MGHgrDatamation,
      MULTIPLE is 0.
    SAVEABLE (Get)
      This is a logical (integer) value that tells users whether the animation
      can usefully be saved. For an MGHgrDatamation, SAVEABLE is 1. (This should be
      changed so that SAVEABLE can be set to 1 if all object references are contained
      in the graphics tree and zero otherwise.)
