Here, we load a simple Web page into the browser () that consists of the current time, made into a hyperlink to the URL. We also attach an instance of a subclass, providing our implementation of . In this case, no matter what the URL, we want to just reload the via .

Settings, Preferences, and Options (Oh, My!)

With your favorite desktop Web browser, you have some sort of “settings” or “preferences” or “options” window. Between that and the toolbar controls, you can tweak and twiddle the behavior of your browser, from preferred fonts to the behavior of Javascript.

Similarly, you can adjust the settings of your widget as you see fit, via the instance returned from calling the widget’s method.
