Chapter 5. JFace Viewers

Although SWT provides a direct interface to the native platform widgets, it is limited to using simple data typesprimarily strings, numbers, and images. This is fine for a large number of applications, but it represents a severe impedance mismatch when dealing with object-oriented (OO) data that needs to be presented in lists, tables, trees, and text widgets. This is where JFace viewers step in to provide OO wrappers around their associated SWT widgets.
