+\section{\class{wxGraphicsContext}}\label{wxgraphicscontext}
+
+A wxGraphicsContext instance is the object that is drawn upon. It is created by a renderer using the CreateContext calls.., this can be either directly using a renderer
+instance, or indirectly using the static convenience CreateXXX functions of wxGraphicsContext that always delegate the task to the default renderer.
