hi every body
i write a simple code into the multiviews example, i add a method to view's container. the code is follow
void CMultiViewsContainer1::DisplayListBox()
{
m_listBox = new (ELeave) CAknSingleStyleListBox();
m_listBox->SetListBoxObserver(this);
m_listBox->SetContainerWindowL(*this);

m_listBox->ConstructL(this, 0);
m_listBox->CreateScrollBarFrameL(ETrue);
m_listBox->ScrollBarFrame()->SetScrollBarVisibilityL(CEikScrollBarFrame::EOn, CEikScrollBarFrame::EAuto);

CTextListBoxModel* model = m_listBox->Model();
MDesCArray* textArray = model->ItemTextArray();
CDesCArray* listBoxItems = static_cast(textArray);
model->SetItemTextArray(listBoxItems);
model->SetOwnershipType(ELbmOwnsItemArray);

TBuf<32> item;
_LIT(KIT1, "item 1");
_LIT(KIT2, "item 2");

item.Format(_L("\t%S\t\t"), &KIT1);
listBoxItems->AppendL(item);
return;
item.Format(_L("%S"), &KIT2);

listBoxItems->AppendL(item);

m_listBox->HandleItemAdditionL();
m_listBox->SetCurrentItemIndexAndDraw(listBoxItems->Count() - 1);
m_listBox->ActivateL();

DrawNow();
}
when i execute it in epoc, i got a error of cbase21, if i do not execute appendl of CDesCArray, it run ok , who can tell me why?

If you want the main item icon to be empty, you'll need to create an icon with no foreground to it and just use its index. If you want the trailing icons to be blank, just exclude them from the item text, such as:

item.Format(_L("%d\t%S"), 0, &KItemName); // 0 = icon index in iconlist

Cheers,

>> item.Format(_L("%d\t%S\t%d\t%d"), 0, &KItemName, 1, 2); // 0, 1, 2 = icon indexes in iconlist

and if for some item i don't want any icon? what should be the symbol then? just a space or "-" don't work...

For Avkon listboxes you will need "aknlists.h".

The following code snippet shows how to create and initialize listbox. Certain parts of initialization are slightly different in case of CEikColumnListBox-derived and CEikFormattedCellListBox-derived listboxes.
