The Inbox page
The first thing most ProjectTrack users will see is the Inbox. Upper Managers will see the Show All page instead, and won't be able to access this page at all. The Inbox is the page that shows all of the projects waiting for processing, and it's the one that users will typically interact with the most. Users can view details, approve, or reject any projects on this page. A mock-up is depicted in figure 9.3. As you can see in figure 9.3, this view has a page header and a panel that contains the...
Starting with HtmlGraphicImage and HtmlOutputText components

RenderKit
A RenderKit represents a collection of Renderer instances, keyed by their type. All of the Renderers within a particular RenderKit instance are usually related in some way.

Other render kits may display different dialects of HTML perhaps DHTML with lots of JavaScript , or some other type of markup altogether, like SVG. Render kits can also be used to provide different skins that use the same type of...
