Remarks

To use, drop the class on a project or form or, from the Component Gallery Item shortcut menu, select Add to Project or Add to Form. When you add the class to a project, you can choose between adding the class or creating a subclass. When you add the class to a form, Visual FoxPro places the class icon on the form. You can then specify the appropriate property values on the form in the Form Designer.
