A little bit more digging found this:
-----%<-----
IDLitVisualization::Is3D
The IDLitVisualization::Is3D function method determines
whether or not this visualization is marked as being
three-dimensional.
Syntax
Result = Obj->[IDLitVisualization::]Is3D()
Return Value
Returns 1 if this visualization is marked as being
three-dimensional, or 0 if it is not three-dimensional.
Arguments
None
Keywords
None
-----%<-----
Based on this I started digging into the various class hierarchies
trying to figure out what is inherited by whom.
Following the list of <Direct> inherited objects...
IDL> help, obj_new('idlitsymbol'), /objects
** Object class IDLITSYMBOL, 1 direct superclass, 4 known methods
Superclasses:
IDLGRMODEL <Direct>
IDLGRCONTAINER
IDL_CONTAINER
IDLGRCOMPONENT
IDLITCOMPONENT
IDL> help, obj_new('idlgrmodel'), /objects
** Object class IDLGRMODEL, 1 direct superclass, 3 known methods
Superclasses:
IDLGRCONTAINER <Direct>
IDL_CONTAINER
IDLGRCOMPONENT
IDLITCOMPONENT
IDL> help, obj_new('idlgrcontainer'), /objects
** Object class IDLGRCONTAINER, 2 direct superclasses, 2 known methods
Superclasses:
IDL_CONTAINER <Direct>
IDLGRCOMPONENT <Direct>
IDLITCOMPONENT
IDL_CONTAINER has no superclasses (I think) so:
IDL> help, obj_new('idlgrcomponent'), /objects
** Object class IDLGRCOMPONENT, 1 direct superclass, 2 known methods
Superclasses:
IDLITCOMPONENT <Direct>
And IDLITCOMPONENT similarly has no superclasses.
So how can IDLITSYMBOL ever get access to the IS3D methjod of
IDLITVISUALIZATION? Via a contained object somehow?
Hmm. Let's go the other way:
IDL> help, obj_new('idlitvisualization'), /objects
** Object class IDLITVISUALIZATION, 2 direct superclasses, 6 known methods
Superclasses:
_IDLITVISUALIZATION <Direct>
_IDLITCONTAINER
_IDLITPROPERTYAGGREGATE
IDLGRMODEL
IDLGRCONTAINER
IDL_CONTAINER
IDLGRCOMPONENT
IDLITCOMPONENT
IDLITSELECTPARENT
IDLITIMESSAGING
IDLITPARAMETER <Direct>
Oi vey!
IDL> help, obj_new('_idlitvisualization'), /objects
** Object class _IDLITVISUALIZATION, 5 direct superclasses, 7 known methods
Superclasses:
_IDLITCONTAINER <Direct>
_IDLITPROPERTYAGGREGATE <Direct>
IDLGRMODEL <Direct>
IDLGRCONTAINER
IDL_CONTAINER
IDLGRCOMPONENT
IDLITCOMPONENT
IDLITSELECTPARENT <Direct>
IDLITIMESSAGING <Direct>
Crikey.
