JQuery is Java browser implemented as an Eclipse plugin. Unlike the standard Eclipse browsers, JQuery is generic: it can be configured to render many different types of views. We will argue that JQuery’s customization-cost profile fits somewhere in between the two extremes offered by modern IDEs. This means that JQuery offers a more cost-effective creation of open-ended browser variations than a plugin architecture. However, it also means that customizing JQuery requires more expertise than clicking GUI buttons. Users may be reluctant to learn the configuration interface. Therefore in this section we present an example illustrating how JQuery 3.1.5 can already be used "out of the box". The example is a fictional scenario in which a developer is exploring the JHotDraw [1] code base. JHotDraw is an application that lets users draw and manipulate a variety of figures such as rectangles, circles, etc. The developer wants to find out how figures are implemented and to find an example of a class that manipulates figures. Figure 2 shows a screenshot of JQuery at the end ofher exploration. We explain the exploration step by step.
