delphi key 各键值对应的编码

procedure TFrmMain.edtKeyPressInPut(Sender: TObject; var Key: Char);begin if not (Key in [#39;0#39;..#39;9#39;, #39;.#39;, #08]) then begin Key := #0; end;end;主要是[#39;...

procedure TFrmMain.edtKeyPressInPut(Sender: TObject;
  var Key: Char);
begin
  if not (Key in ['0'..'9', '.', #08]) then
  begin
    Key := #0;
  end;
end;

 

主要是['''''''']里面的表达,两者之间用‘,’号隔开,相关的键盘代码是:
