问题五：如何在Container中List控件和图片控件切换

void CMyContainer::Draw(TRect aRect)

{

CWindowGc& gc = SystemGc();

gc.SetPenStyle( CGraphicsContext::ENullPen );

gc.SetBrushColor( KRgbGray );

gc.SetBrushStyle( CGraphicsContext::ESolidBrush );

gc.DrawRect( aRect );

if(iImage)

{

gc.Clear();

gc.BitBit(TPoint(0,0), iImage);

}

}

CCoeControl* CMyContainer::ComponentControl(TInt aIndex) const

{

switch(TInt nIndex)

{

case 0:

if(iImage)

iListBox->MakeVisue(EFalse);

else

iListBox->MakeVisue(ETrue);

}

}

void CMyContainer::ShowImage()
