Figure 1. Emulate Web Navigation With Avalon Windows.
The Hands-On Labs' ExpenseIt solution (HOL-002, Exercise 17) demonstrates navigation between two Avalon windows. You select a person in the "Create an expense report" window (top) and click on Create Report to navigate to the expense report window (bottom). Clicking on the forward navigation arrow returns you to the "Create an expense report" window. (Why the design uses the forward-navigation arrow for this instead of the backward-navigation arrow is a mystery.) The graphical elements are bitmaps for the PDC preview; future examples will substitute vector graphics. The Longhorn SDK's ExpenseIt sample application is a hosted version of HOL-002 that demonstrates a more conventional window-navigation approach.
