+Use native or custom-drawn decorations for this window only. Notice that to
+have any effect this method must be called before really creating the window,
+i.e. two step creation must be used:
+\begin{verbatim}
+    MyFrame *frame = new MyFrame;           // use default ctor
+    frame->UseNativeDecorations(false);     // change from default "true"

+
+Top level windows in wxUniversal port can use either system-provided window
+decorations (i.e. title bar and various icons, buttons and menus in it) or draw
+the decorations themselves. By default the system decorations are used if they
+are available, but this method can be called with \arg{native} set to \false to
+change this for all windows created after this point.
+
+Also note that if \texttt{WXDECOR} environment variable is set, then custom
+decorations are used by default and so it may make sense to call this method
+with default argument if the application can't use custom decorations at all
+for some reason.
