+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="GUID-0C4B86B5-530A-5839-86C1-46E7ABE281E0.dita">Introduction
+to the window server</xref>.</p>
+<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 
+    { 
+    EEventNull, 
+    EEventKey, 
+    EEventKeyUp, 
+    EEventKeyDown, 
+    EEventModifiersChanged, 
+    EEventPointer, 
+    EEventPointerEnter, 
+    EEventPointerExit, 
+    EEventPointerBufferReady, 
+    EEventDragDrop,
