代码：
1 unit Unit1; 2 3 interface 4 5 uses 6 Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics, 7 Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Vcl.ExtCtrls; 8 9 type 10 TForm1 = class(TForm) 11 Shape1: TShape; 12 Button1: TButton; 13 Button2: TButton; 14 Timer1: TTimer; 15 procedure Button1Click(Sender: TObject); 16 procedure Button2Click(Sender: TObject); 17 procedure Timer1Timer(Sender: TObject); 18 private 19 { Private declarations } 20 public 21 { Public declarations } 22 end; 23 24 var 25 Form1: TForm1; 26 27 implementation 28 29 {$R *.dfm} 30 31 procedure TForm1.Button1Click(Sender: TObject); 32 begin 33 Shape1.Shape := stEllipse; //图形的类型 椭圆 34 Shape1.Pen.Style := psSolid; //图形边框的类型 35 Shape1.Pen.Color := clGreen; //图形边框的颜色 36 Shape1.Brush.Color := clRed; //图形填充的颜色 37 Shape1.Brush.Style := bsVertical; //图形填充的类型 38 39 end; 40 41 procedure TForm1.Button2Click(Sender: TObject); 42 begin 43 Timer1.Enabled := True; //让time执行 44 end; 45 46 procedure TForm1.Timer1Timer(Sender: TObject); 47 begin 48 Shape1.Left := Shape1.Left + 1; //让shape走起 49 if Shape1.Left = 888 then //走到888 返回 50 Shape1.Left := 22; 51 end; 52 53 end.
