MGH_GUI_LIGHTEDITOR__DEFINE

Class


  MGH_GUI_LightEditor

Purpose


  This class implements a GUI application with a single CW_LIGHT_EDITOR
  widget.

Category


      Widgets.

Properties


  The following properties are supported:
    CLIENT (Init, Get, Set)
      A reference to the object with which this object will exchange
      information. The client must support GetProperty and
      SetProperty methods which accept 'PROPERTY_NAME' as a
      keyword. It must also support Update and Show
      methods. (Subclasses of MGH_GUI_Base inherit Update and Show.)
  Several other properties are inherited unaltered from the superclass, MGHwidgetBase.
  The following property is inherited with additional functionality:
    MANAGED (Init, Get)
      This keyword can still be retrieved via GetProperty, but in
      addition it is accepted by the Init method, where it specifies
      whether Init should call the Manage method. The default (1 =
      manage the object immediately) allows a simpler creation
      sequence and will normally be satisfactory *except* when the
      widget application is (or could be) blocking and there is some
      reason to interact with it programmatically--in a way that
      requires its widgets to be intact--after initialisation.
      (Recall that the Manage method of a blocking widget object
      does not return until the widget hierarchy has been
      destroyed.) For example a subclass of MGH_GUI_LightEditor
      might call MGH_GUI_LightEditor::Init with MANAGED=0 then call
      the Manage method at the end of its own initialisation
      prcoess.
