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
- Sharing Information and Adding OLE
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 |
