ViSUAL Attributes & property clauses
89. What are visual attributes?
Visual attributes are the font, color, pattern proprities that you set
for form and menu objects that appear in your application interface.
90. What is a property clause?
A property clause is a named object that contains a list of properties
and thier settings. Once you create a property clause you can base
other object on it. An object based on a property can inherit
the setting of any property in the clause that makes sense for that
object.
91. Can a property clause itself be based on a property clause?
Yes
92. What are the important difference between property clause and
visual attributes?
Named visual attributes differed only font, color & pattern
attributes, property clauses can contain this and any other
properties. You can change the appearance of objects at run time
by changing the named visual attributes programatically , property
clause assignments cannot be changed programatically. When an object
is inheriting from both a property clause and named visual
attribute, the named visual attribute settings take precedence, and
any visual attribute properties in the class are ignored.
