Overview of iTools Compound Widgets
The compound widgets described in this appendix provide the base functionality
needed to create an iTool user interface using IDL widgets. These widgets are useful
only in the context of creating an iTool interface; they require the presence of the
iTools system object to function properly. Attempts to use these widgets outside the
context of the iTools will not succeed.
Before attempting to use these compound widgets to create an iTool user interface,
you should be familiar with (at a minimum) the following concepts:
• The iTool object hierarchy (see Chapter 2, “iTool System Architecture”)
• Creating an iTool (see Chapter 5, “Creating an iTool”)
• iTool user interface concepts (see Chapter 11, “iTool User Interface
Architecture”)
• Creating an iTool interface using IDL widgets (see Chapter 15, “Creating a
Custom iTool Widget Interface”)
