The form is referred to as the Parent, while the text boxes are referred to as children (or child controls). A good example of a container is a form that contains a group of text boxes. (The “control” control is somewhat of an exception to this rule, since it allows us to refer to multiple controls as if they were one). The difference is that a container can include other controls or even other containers within itself, while a control cannot. These built-in classes are called base classes.īase classes are grouped into controls and containers. The model includes a set of built-in classes that you use as a basis for creating your own classes. User defined classes, protected class members, inheritance, - everything you would expect to find in a robust object model. The Visual Foxpro object model is based on a strong foundation of object-oriented principles. Alan Griver, ISBN 0-7821-1648-5, Copyright ©1995 SYBEX Inc.,by permission of SYBEX Inc.
