}

注意，要使编辑框正常显示，记得更改container的CountComponentControls和ComponentControl函数，正确处理控件数目和编辑框指针。另外，要使编辑框能正常接收按键事件，要显示调用编辑框的OfferKeyEventL函数，如下：

Code:

TKeyResponse CMobileGuardSetKeyContainer::OfferKeyEventL( const TKeyEvent& aKeyEvent, TEventCode aType )

{

return iGKeyEd->OfferKeyEventL( aKeyEvent, aType );

}
