Remarks

This general purpose Window Handler class performs several common window operations such as cascading windows.

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 displays the icon on the form so you can specify appropriate properties values its available methods in the Form Designer.

See Guidelines for Using Visual FoxPro Foundation Classes for more information on using foundation classes.
