Configuring Views and Context
For a user interface component to be useful it must display relevant information. In most
cases this information is not static, but is supplied by agents collecting data on an
ongoing basis. Thus, there are two major requirements for a user interface framework—
a rich set of visual components and a data binding mechanism. Queries are useful for
retrieving data from a data source, but context is the usual mechanism for sharing the
data among related views. This chapter discusses the tools for building visual
components and describes how context is used to pass data among the various views
that have a need for that data.
