7. Scope • The zone of visibility for a class, object, procedure, etc. • Many scope qualifier keywords, ex., • Public: visible to the entire project • Private: visible only to the current module • Encapsulation – hiding the inner workings of a class or child object; using scope qualifiers to create an interface between public and private, as with a TV remote The University of North Texas, ITDS Dept., Dr. Vedder

Assigning Values to Properties • Template – theme with default text • Theme – collection of styles applied to entire document • Style – collection of formats applied to a section of a document • Individual format (of a selected object); anything the developer can see on the screen is an object, especially if selectable.
