The iTools component framework is a set of object class definitions written in the
IDL language. It is designed to facilitate the development of sophisticated

IDL language. It is designed to facilitate the development of sophisticated
visualization tools by providing a set of pre-built components that provide standard
features including:
•
creation of visualization graphics
•
mouse manipulations of visualization graphics
•
annotations
•
management of visualization and application properties
•
undo/redo capabilities
•
data import and export
•
printing
•
data filtering and manipulation
•
interface element event handling
In addition, the iTools component framework makes it easy to extend the system with
components of your own creation, allowing you to design a tool to manipulate and
display your data in any way you choose.

Advantages of Using the Framework
If you are accustomed to creating user interfaces for your IDL applications using IDL
widgets, using the iTools component framework will shorten your development time
by providing much of the application interface via the standard component building
blocks. In many cases, you are freed entirely from the need to create your own
interface elements, handle widget events, and manage the display of data. Even when
your application calls for additional user interface elements, the framework
eliminates the need for you to manually create those elements that your application
has in common with the standard iTool interface.

If you are accustomed to using IDL object graphics in your applications, the iTools
component framework provides a streamlined way of working with the object
graphics hierarchy. Many tasks, such as management of object properties and
manipulation of the object model, are handled automatically.
