This page provides a list of examples. Some demonstate a specific application, while others show a tool/technique that is generically useful. In the latter case you can import the widget using e.g. from flexxamples.howtos.editor_cm import CodeEditor.

Note that most examples are written in such a way that they work in the browser (by subclassing Widget). If you are creating a desktop application, you probably want to use PyWidget to create your high-level widgets instead.
