public class MyProject_IP

extends PjProject_IP

implements java.awt.event.ActionListener

Info panel of tutorial project. Each project, as well as each geometry, may have an info panel for inspecting and steering the instance. Modifications in the panel should result in a call to project.update(Object).

Panel adds simple sliders for modifying integer values of the project. The sliders are children of the project and send update(Object) whenever they change by user interaction.

This info panel is optional and can be removed without any changes in the project. Each info panel must follow special naming conventions such that JavaView is able to show it automatically, or on request. The class name must be identical to the class name of the corresponding class with the suffix '_IP' attached. IP means InfoPanel.

Version:

28.11.00, 1.50 revised (kp) Applet simplified for beginners.
20.03.00, 1.10 revised (kp) Sliders moved to project.
05.08.99, 1.00 created (kp)
