Web Component Guide
A context mechanism allows values, which may be objects, to be passed to
dependent pages. Thus, dynamically retrieved data on a parent page can be passed
to a dependent page.
The starting place for working with Web Component Framework components is the
Definitions choice. You may find it useful to have vFoglight open on the Definitions
page so that you can refer to it as you continue reading.
View Components
View components are the visible components in the user interface. Multiple components
can be arranged on a page and some components can be nested within others. A view
contains both view components and configuration information.
Types of view components:
Containers, such as various layouts, splitters, and reports
Data visualization components, such as charts, tables, gauges, labels, and trees
Specialized components, such as RSS feeds
The configuration settings include flow control, contextual inputs, data binding, and
query specification. Views can be configured using:
A query— to provide data binding.
A context—what is shown in the view depends on the context passed to the page
or component.
A flow—an action to be performed based on user input, such as a selection of a
particular item on the parent page that launches a drill down page based on the
context.
The vFoglight User Guide covers the following topics in greater detail.
Pages can be decorated with headers, which may contain:
Breadcrumbs—the present page name preceded by other page names
Time Region—which may contain
Timestamp: if no time range is applied to the page
Time Range: if available and applies to all views
A Zonar: if available, permits a choice of the time interval
Nothing: if multiple time ranges are represented
Optional Page Scope Actions, such as
