delphi中关于TRect

var
  r:TRect;
begin
  
    r:=ClientRect;
    r.TopLeft:=Parent.ScreenToClient(ClientToScreen(r.TopLeft));
    r.BottomRight:=Parent.ScreenToClient(ClientToScreen(r.BottomRight));
 end;

TRect成员没有TopLeft或者是BottomRight啊，写成C++应该是什么样的呢？

[解决办法]

TRect r = ClientRect;
TPoint pt;

pt.x = r.Left;
pt.y = r.Top;
pt = Parent->ScreenToClient(ClientToScreen(pt));
r.Left = pt.x;
r.Top = pt.y;

pt.x = r.Right;
pt.y = r.Bottom;
pt = Parent->ScreenToClient(ClientToScreen(pt));
r.Right = pt.x;
r.Bottom = pt.y;

PS: 高版本的C++Builder中, TRect就有了TopLeft和BottomRight成员了.
