Predefined iTool Visualization Classes
The iTool system distributed with IDL includes a number of predefined visualization

visualization classes. You can include these visualization classes in an iTool directly
by registering the class with your iTool (as described in
classes. The visualization type (the TYPE keyword value of the visualization with
which it is initialized) and the accepted data type(s) are shown for the predefined
visualization classes. You can include these visualization classes in an iTool directly
by registering the class with your iTool (as described in
on page 136). You can also create a new visualization class based on one of the
predefined classes. Visualization classes are located in the
lib/itools/components
subdirectory of the IDL directory.
