Android Fragment и getWindow()

public class AircraftFragmentTab extends Fragment{
  private String ac;

  public AircraftFragmentTab(String AC){
      ac = AC;

  }
     @Override
     public View onCreateView(LayoutInflater inflater, ViewGroup container,
     Bundle savedInstanceState)
     {
         View aircraftView = inflater.inflate(R.layout.acdetails, container, false);

         ??? getWindow().setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
          WebView wv = (WebView) aircraftView.findViewById(R.id.webac);
          wv.getSettings().setJavaScriptEnabled(true);
          wv.loadUrl("http://ABCD/ACInfo.aspx?AC=" + ac);

         return aircraftView;
     }

}

Я использую webView, и класс распространяется от Fragment. Как я могу использовать getWindow() здесь?
