如何在Delphi中用回车键切换输入焦点

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.

将窗体的keypreview:=true{按回车件使下一控件得到焦点}procedure checkformkeypress(aform tobject; var key: char);begin if key=#13 then if not (sender is tbutton) then begin key0; aform.perform(wm_nextdlgctl,0,0); {移动到下一个控件} end;end;
