BCB中控件數組的簡易實現

      網上有控件數組實現的多個方法,今天發現了Delphi的一個簡單版本,欣喜而外,特翻譯成bcb.

      1,若有多個相同類的控件,比方說,TEdit,為了簡化逐個操作,可通過其Index屬性.

      2,若直接放在Form上,則用Components[]屬性.比如:

      void __fastcall TForm1::Button1Click(TObject *Sender)
     {
                   for(int i = 0;i < Form1->ControlCount;++i)
                  {
                           if( dynamic_cast <TEdit *>(Form1->Components[i]) )

                                    {

                           dynamic_cast <TEdit *>(Form1->Components[i])->Color = clRed;
                           dynamic_cast <TEdit *>(Form1->Components[i])->Text = IntToStr(i);

                           }
                  }
    }

   3,若將控件組成一起,用Panel容器,則使用Panel的Controls[]屬性,比如:

    for(int i = 0;i < Form1->Panel1->ControlCount;++i)
    {
            dynamic_cast <TEdit *>(Form1->Panel1->Controls[i])->Color = clRed;
            dynamic_cast <TEdit *>(Form1->Panel1->Controls[i])->Text = IntToStr(i);
    }
