+server events</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>Window server events are an important part of the application framework.
+They allow applications to receive information regarding key presses, pointer
+activities, application switches, and focus transitions. </p>
+<p>Every application has at least a <xref href="GUID-FD2CDEB8-0784-4BE5-A775-170F57D71BBC.dita">UI
+controller</xref>, which is the root for all other controls owned by the application.
+When an event occurs under the window server, the window server passes the
+event to the UI controller and possible other controls, depending on the event
+and the architecture of your application.</p>
+<p>For more information on the window server, see <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/guide/Graphics-subsystem-guide/WindowServerClientSide/WindowServerGuide1/WindowServerIntroduction.guide.html#WindowServerGuide1%2eintro" format="application/java-archive">Introduction to the window server</xref>.</p>
+<p>The following window server events have a special function:</p>
+<ul>
+<li><p><xref href="GUID-E402616A-7ED8-45AC-B836-99C3A3760B33.dita">Key events</xref></p>
+</li>

+change events</xref></p>

+</li>
+</ul>
+<p>The framework provides different functions to handle each type of event
+separately. You must implement these functions for the events to be handled
+by your application.</p>
+<p> All the window server event types are defined in the <parmname>w32std.h</parmname> header,
+and are as follows:</p>
+<codeblock id="GUID-2F04E088-73B0-4006-903D-4651223E0434" xml:space="preserve">enum TEventCode 
+    {

+    EEventPointer,
