PRB: Cannot Add Methods to Objects at Design Time (130325)
The information in this article applies to:
- Microsoft Visual FoxPro for Windows 3.0
This article was previously published under Q130325 SYMPTOMS
Selecting the Form, New Property option while a control is highlighted does
not add a property to a control. The new property is added to a form.
CAUSE
This is by design. When a form is created with the CREATE FORM or MODIFY
FORM commands, a form object is instantiated, and instances of objects are
manipulated in design mode. Generally, a property cannot be added to an
object once it is instantiated, and to modify a visual class, it is
necessary to use the Class Designer. However, a special case has been made
to the Form designer, where the form is subclassed to allow the creation of
form properties and methods at form design time. This feature is not
available for controls.
WORKAROUND
Use the Class Designer to modify the class definition of a control. For
more information about using custom objects in a Form, refer to the 'Adding
User Defined Objects' paragraph in the Visual FoxPro "Developer's Guide,"
Chapter 9, "Creating Forms."
STATUS
This behavior is by design.
