Question

delphi 用memo控件实现全选功能

Answer 1

使用Memo1的OnKeyDown事件
procedure TForm1.Memo1KeyDown(Sender: TObject; var Key: Word;
Shift: TShiftState);
begin
if (Shift =[ssCtrl]) and (Key=65) then
Memo1.SelectAll;
end;

在光标在Memo控件中时使用快捷键Ctrl+A实现全选

Answer 2

procedure TForm1.Button1Click(Sender: TObject);
begin
Memo1.SetFocus;
Memo1.SelectAll;
end;
要复制到剪贴板就加上下面这行
Memo1.CopyToClipboard;
