Text in der Titelzeile zentrieren

[Luckie]

Delphi-Quellcode:

procedure TForm1.WMNCPAINT(var Msg: TMessage);
var
  rect: TRect;
  dc: HDC;
  MyCaption: String;
begin
  Inherited;
  if Msg.Msg = WM_NCPAINT then
  begin
    dc := GetWindowDC(Handle);
    rect.Left := GetSystemmetrics(SM_CXEDGE);
    rect.Top := GetSystemmetrics(SM_CYEDGE)+2;
    rect.Right := Form1.Width-GetSystemmetrics(SM_CXEDGE);
    rect.Bottom := GetSystemmetrics(SM_CYCAPTION)+GetSystemmetrics(SM_CYEDGE);
    SetBkMode(dc, TRANSPARENT);
    SetTextColor(dc, RGB(255,255,255));
    MyCaption := 'Meine zentrirte Fenster-Caption';
    DrawText(dc, @MyCaption[1], lstrlen(@MyCaption[1]), rect, DT_CENTER or DT_VCENTER);
    ReleaseDc(Handle, dc);
  end;
end;
