===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]]
