我有一个 Delphi XE2 项目来显示滚动文本。我的代码如下:
unit Unit1;
interface
uses
Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.ExtCtrls, Vcl.StdCtrls;
type
TForm1 = class(TForm)
Label1: TLabel;
Timer1: TTimer;
procedure Timer1Timer(Sender: TObject);
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
procedure TForm1.FormCreate(Sender: TObject);
begin
Label1.Caption := 'This is right scrolling text ';
Timer1.Enabled := true;
end;
procedure TForm1.Timer1Timer(Sender: TObject);
var
S: String;
begin
S := Label1.Caption;
S := S[Length(S)] + Copy(S, 1, Length(S) - 1);
Label1.Caption := S;
end;
end.
使用以下代码,文本沿 Y 轴在 2d 中完美滚动。
