Addition of Objects to Forms
To design the functionality you want in a form, you add the appropriate controls, set form and control properties, and write event code.
You can add the following types of objects to a form:
- Controls
- Containers
- User-defined classes
- OLE objects
Understanding Container and Control Objects
Objects in Visual FoxPro belong in one of two categories, depending on the nature of the class they are based on:
- Containers can hold other containers or controls. They can act as the parent object for other objects. For example, a form, as a container, is the parent object of a check box on that form.
- Controls can be placed in containers, but cannot be the parent for other objects. For example, a check box cannot contain any other object.
The Form Designer allows you to design both containers and controls.
| Container | Can contain |
|---|---|
| Column | Headers, and any objects except form sets, forms, toolbars, timers, and other columns |
| Command button group | Command buttons |
| Form set | Forms, toolbars |
| Form | Page frames, grids, any controls |
| Grid | Columns |
| Option button group | Option buttons |
| Page frame | Pages |
| Page | Grids, any controls |
