7.1.4 Examining other classes

There are two ways that you can examine other classes. The first is to type the name of the class you wish to see into the Class text box at the top of the browser. Press Return or click and the named class is described.

1. While still examining class capi:list-panel , type capi:push-button-panel into the Class area.

The class capi:push-button-panel is described.

Because some class names may be potentially quite long, you can use completion to reduce typing. If you press when you have partially specified the name of a class in the Class text box, the environment attempts to complete what you have typed. If it cannot complete the class name, a dialog appears that lists all the possible alternatives. Double-click on any of these alternatives to place it in the Class text box. Finally click on to make this the class being described.

The second way to examine other classes is by using the Superclasses and Subclasses lists available in the hierarchy view. Click on the Hierarchy tab to display the hierarchy view.

The main part of the hierarchy view consists of two lists:

• The Superclasses list shows all the superclasses of the current class.
• The Subclasses list shows all the subclasses of the current class.

Double-click on any superclass or subclass of the current class to examine it.

1. Double-click on CAPI:BUTTON-PANEL in the Superclasses list.

The capi:button-panel class is described.

2. Double-click on CAPI:PUSH-BUTTON-PANEL in the Subclasses list.

The capi:push-button-panel class is described again.

So, using the Hierachy tab, you can easily look through the related classes in a system.
