Visual Component Library

Builder possesses a large range of in-built classes and visual components. Each class and its properties are readily available by using Builders own Help function.

Inheritance plays a key role in the class system. Ancestors and dependents abound throughout. In the hierarchy TObject is the base class from which all VCL components are derived. New classes can be formed using an existing class that has the required behaviour and then adding the new behaviour specified.

Windows is an event-driven environment. The event is triggered by the users interaction with a component at the interface. Events require event handler code.
