196 Chapter 8: Creating a Manipulator
Overview of iTool Manipulators iTool Developer’s Guide
When you initialize a manipulator, you can define the type of selection visual that
appears by setting the VISUAL_TYPE keyword to the Init method. If you create a
custom IDLitManipulatorVisual object, then the VISUAL_TYPE property values of
the IDLitManipulator and IDLitManipulatorVisual objects are the same. Unless
otherwise specified, a custom manipulator will retain the selection visual of the last
active manipulator.
Note
Creation of IDLitManipulatorVisual objects is beyond the scope of this chapter.
However, you may examine the
IDLitManipVis* classes in the
lib\itools\components subdirectory of the IDL installation directory as
guides if you choose to create a selection visual.
