请教为button按钮被按次数 计数
一个edit 一个button1按钮
i：＝0
按一下button1按钮 i：＝i+1
同时在edit中显示出按钮被按的次数，也就是i的数字

把i设国全局变量。
var
i:integer;
procedure Tform1.Button1click(sender:Tobject)
begin
i:=i+1;
edit1.text:=inttostr(i);
end;

unit Unit1;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;

type
TForm1 = class(TForm)
Button1: TButton;
Edit1: TEdit;
procedure Button1Click(Sender: TObject);
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
i: integer;
end;

var
Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
inc(i);
edit1.Text := inttostr(i);
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
i := 0;
end;

end.

加button1.onclick 事件中
edit1.text := Strtointdef(edit1.text,0) + 1 ;

定义i为全局变量

var
i:integer;
........

procedure TForm1.Button1Click(sender: TObject);
begin
i:=i+1;
Edit1.text:=inttostr(i);
end;

接受答案了.
