Delphi 自定义窗体类名

原理就是覆盖原CreateParams函数，重写新CreateParams函数，在新CreateParams函数继承完之后马上修改Parames.WinClassName

type
  TForm1 = class(TForm)
  private
    { Private declarations }
  public
    procedure CreateParams(var Parames: TCreateParams); override;
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}
procedure TForm1.CreateParams(var Parames: TCreateParams);
begin
  inherited CreateParams(Parames);
  Parames.WinClassName := 'newClass';
end;
