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 iTool System Architecture)
- Creating an iTool (see Creating an iTool)
- iTool user interface concepts (see iTool User Interface Architecture)
- Creating an iTool interface using IDL widgets (see Creating a Custom iTool Widget Interface)
