Answer 1

回车后转移焦点：
 
unit Unit1;
 
interface
 
uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls;
 
type
  TForm1 = class(TForm)
    Edit1: TEdit;
    Edit2: TEdit;
    Button1: TButton;
    procedure Edit1KeyPress(Sender: TObject; var Key: Char);
    procedure Edit2KeyPress(Sender: TObject; var Key: Char);
  private
    { Private declarations }
  public
    { Public declarations }
  end;
 
var
  Form1: TForm1;
 
implementation
 
{$R *.dfm}
 
procedure TForm1.Edit1KeyPress(Sender: TObject; var Key: Char);
begin
     if key=#13 then edit2.SetFocus;
end;
 
procedure TForm1.Edit2KeyPress(Sender: TObject; var Key: Char);
begin
      if key=#13 then button1.SetFocus;
end;
 
end.
