Figure 10.4 The JavaFX Weather Widget

The widget's GUI is a JavaFX scene that contains a group of three main compo-
nents: title text, a progress bar, and a vertical box that contains the individual
weather text components. Some of the code for this is shown in Listing 10.6. The
progress bar remains hidden until a request is made to a REST service, at which
point it's made visible and is activated. When all of the requested data is
received, it's hidden again.
