{ 
  When you set the BiDiMode in you form to bdRightToLeft, you do only HALF mirroring. 

  Since Win98 (Hebrew/Arabic version) mirror it's envirement completly 
 (the Minimize, Close, Maxmize buttons are on the Left, and the Icon is on the right). 
  How can we do it in delphi ?

     procedure CreateParams(var Params : TCreateParams); override;
   end;

 implementation

 procedure TForm1.CreateParams(var Params : TCreateParams);
 begin
   inherited CreateParams(Params);
   Params.ExStyle := WS_EX_LEFT or WS_EX_RTLREADING or WS_EX_LEFTSCROLLBAR or WS_EX_LAYOUT_RTL;
  {WS_EX_LEFT to set the text caption to the right, 
  use WS_EX_RIGHT to set the caption to the left}
 end;

 procedure TForm1.FormCreate(Sender: TObject);
 begin
  BiDiMode := bdLeftToRight; //A must !!! 
end;

 {The result is Right to Left (including the buttons, the icon and the system menu) }
