The destroyOnClose property specifies you want the view destroyed and all dependencies released when the window closes, even if the parent window remains open. Make sure you set the destroyOnClose property before the view is created using one of the open actions.

The partName property specifies the name you want to use to describe the part. For nonvisual parts, this text appears under the icon for the part on the free-form surface.

The name of the part can consist of alphanumeric characters, and must be different from those of all other parts on the layout surface.

If you do not specify a part name, VA Smalltalk generates a unique name based on the class name of the part.

The viewPartClass property is the part class being wrapped. It is this class that will be instantiated when one of the view creation actions is used.
