Window-Oriented View Hierarchy
Here is a schematic representation of the window-oriented view hierarchy, with the corresponding classes also shown.
Parent-Child Relationships
The terms “parent” and “child” designate the relationship
C++ classes and subclasses also represent parent-child relationships. Note that there is no one-to-one correspondence between the window-oriented versus class-oriented view hierarchies. The C++ class hierarchy is a different way of looking at how a view is constructed. For the complete class-oriented diagram, see the Class-Oriented View Hierarchy.
