The usual way to obtain such a context, when drawing to the screen, is by <codeph>CCoeControl::SystemGc()</codeph>. This returns a concrete Window Server graphics context, of type <codeph>CWindowGc</codeph>, which is derived from <codeph>CGraphicsContext</codeph>. </p> </conbody><related-links><link href="GUID-1E68A78A-52E5-5DF7-B540-85C7194E4617.dita"><linktext>Graphics Device
