-===What Is a Widget?===
-TBD
-===Widget Hierarchy.===
-RWT uses the same widget hierarchy as SWT. In addition the class
-<code>Widget</code> implements Adaptable.
-===Events and Listeners.===
-RWT implements the SWT events as close as possible. Through
-the distributed nature of RWT e.g. key-stroke events with
-server-side turnarounds for event processing won't be available
-since the network latency is too big to make such events usefully
-applicable.
-Currently RWT does not implement ''untyped Listeners'' as SWT does.
-Therefore all related methods (like Widget.notifyListeners(int,Event))
-are missing.
-===Application Data.===
-Works the same as in SWT.
-All methods for both, named and unnamed application data, are
-implemented.
-===Querying the Display===
-Though RWT provides a class Display as well and Widget provides the <code>getDisplay()</code> method, the meaning of Display in RWT is
-somewhat different.
-Display is described in more detail in the chapter [[5. Display.|Display]]
