What is a visual attribute (VAT) ?

Visual attributes are the font, color, and pattern properties that you set for form and menu objects that appear in your application's interface.

Named visual attributes define only font, color, and pattern attributes; property classes can contain these and any other properties. You can change the appearance of objects at runtime by changing the named visual attribute programmatically; property class assignment cannot be changed programmatically. When an object is inheriting from both a property class and a named visual attribute, the named visual attribute settings take precedence, and any visual attribute properties in the class are ignored.
