如何在Delphi中使用剪贴板

通过剪贴板实现剪切、复制、粘贴操作：

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    Memo1: TMemo;
    Button1: TButton;
    Button2: TButton;
    Button3: TButton;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);  // 剪切
begin
     memo1.CutToClipboard;
     memo1.SetFocus;
end;

procedure TForm1.Button2Click(Sender: TObject);   // 复制
begin
     memo1.SelText;
     memo1.CopyToClipboard;
     memo1.SetFocus;
end;

procedure TForm1.Button3Click(Sender: TObject);  // 粘贴
begin
    memo1.PasteFromClipboard;
    memo1.SetFocus;
end;

end.

剪切板类 TClipboard 定义在 Clipbrd 单元, 使用前先要 uses Clipbrd; [Delphi] view plaincopyprint?
uses Clipbrd;

procedure TForm1.Button1Click(Sender: TObject);
var
clip: TClipboard;
begin

clip := TClipboard.Create; {建立}

clip.AsText := Self.Text; {把窗体标题放入剪切板}
ShowMessage(clip.AsText);
{从剪切板读取, 返回结果是: Form1}{因为剪切板是全局的, 此时可以在其他地方粘贴一试}
clip.Free; {释放}
end;
