Application Structure


Mobile applications differ from desktop applications in that rather than having multiple panels visible at once on a large screen, they are typically divided into smaller segments designed to be displayed one at a time on a small screen. Lengthy forms, such as a customer-detail form whose desktop version includes {{ListGrid}}s displaying the customer's past invoices, may be broken up so that the main panel showing the customer's name, contact information, and so on instead has a navigation link to a new panel containing just a list of the invoices (each of which, in turn, is a link to a page showing the invoice ID, date, totals, and so on). applications are still GWT applications, however, and the standard application lifecycle is unchanged: Applications declare an entry-point module and set up their top-level interfaces in onModuleLoad().  Basic History management is built into without needing any effort from the developer; see below.

Layout and Navigation

Since mobile applications are typically both smaller than desktop  applications and more tightly coupled in their navigation structure  between panels, the suggested model for navigation is for event handlers to directly invoke navigation methods such as NavStack's push and pop.
