系统提示为错误
请问是为什么？真不明白！unit Unit1;interfaceuses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ExtCtrls;type
  TForm1 = class(TForm)
    Edit1: TEdit;
    RadioGroup1: TRadioGroup;
    GroupBox1: TGroupBox;
    CheckBox1: TCheckBox;
    CheckBox2: TCheckBox;
    CheckBox3: TCheckBox;
    CheckBox4: TCheckBox;
    procedure RadioGroup1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;var
  Form1: TForm1;implementation{$R *.dfm}procedure TForm1.RadioGroup1Click(Sender: TObject);
begin
edit1.Font.Name:=radiogroup1.Items（radiogroup1.itemindex）;
end;end.

Answer 1

edit1.Font.Name:=radiogroup1.Items[radiogroup1.itemindex];

Answer 2

给你原代码吧，看你连这个都不知道，省得你麻烦，直接复制过去就可以了。unit Unit1;interfaceuses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ExtCtrls;type
  TForm1 = class(TForm)
    Edit1: TEdit;
    RadioGroup1: TRadioGroup;
    GroupBox1: TGroupBox;
    CheckBox1: TCheckBox;
    CheckBox2: TCheckBox;
    CheckBox3: TCheckBox;
    CheckBox4: TCheckBox;
    procedure RadioGroup1Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;var
  Form1: TForm1;implementation{$R *.dfm}procedure TForm1.RadioGroup1Click(Sender: TObject);
begin
edit1.Font.Name:=radiogroup1.Items[radiogroup1.itemindex];
end;end.好了吗？

Answer 3

edit1.Font.Name:=radiogroup1.Items（radiogroup1.itemindex）;
哈哈，也给我点分吧edit1.Font.Name:=radiogroup1.Items[radiogroup1.itemindex];
