+    @class wxGDIObject
+    @wxheader{gdiobj.h}
+    
+    This class allows platforms to implement functionality to optimise GDI objects,
+    such
+    as wxPen, wxBrush and wxFont. On Windows, the underling GDI objects are a
+    scarce resource
+    and are cleaned up when a usage count goes to zero. On some platforms this
+    class may not have any special functionality.
+    
+    Since the functionality of this class is platform-specific, it is not
+    documented here in detail.
