Delphi中實現漢字拼音聲母查詢

編輯:Delphi

  Delphi中實現漢字拼音聲母查詢,unit代碼如下:
  
  unit Unit1;

  interface

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

  type
    TForm1 = class(TForm)

      ListBox2: TListBox;
      Edit1: TEdit;
      Label1: TLabel;
      procedure Edit1Change(Sender: TObject);
      procedure FormShow(Sender: TObject);
      procedure FormDestroy(Sender: TObject);
      procedure Edit1Enter(Sender: TObject);
      procedure Edit1Exit(Sender: TObject);
    private
      { Private declarations }
    public
