如何添加列表

1 CEikColumnListBox* iListBox;

2 建立:

iListBox = new ( ELeave ) CAknSingleNumberStyleListBox();     

iListBox->SetContainerWindowL( *this );

銷毀:

if( iListBox ) delete iListBox; 

3 添加:

CDesCArray* itemArray =

        static_cast<CDesC16ArrayFlat*>(iListBox->Model()->ItemTextArray());

itemArray->AppendL();

iListBox->HandleItemAdditionL();

CCoeControl

重載:

TInt CountComponentControls() const;

{return 1; }

CCoeControl *ComponentControl(TInt aIndex) const;

{switch( aIndex )

        {

        case 0:

            return iListBox;

        default:

            return NULL;               

        }

}

void SizeChanged();

{if ( iListBox )

        {

        iListBox->SetRect( Rect() );

        }

}

TKeyResponse OfferKeyEventL(const TKeyEvent &aKeyEvent, TEventCode aType); 

if ( aKeyEvent.iCode == EKeyDownArrow || aKeyEvent.iCode == EKeyUpArrow )

        // Forward key events to listbox               

        return iListBox->OfferKeyEventL( aKeyEvent, aType );

   

    return EKeyWasNotConsumed;   

 

ConstructL:

CreateWindowL(); // Creates window.       

    SetRect( aRect ); // Sets rectangle of frame.

       

    CreateListboxL();

    iListBox->SetRect(Rect());

    iListBox->MakeVisible( ETrue );

    iListBox->SetFocus(ETrue);

   

    ActivateL(); // Activates window. ( Ready to draw )   

 

CreateListboxL

 

iListBox = new ( ELeave ) CAknSingleNumberStyleListBox();

iListBox->SetContainerWindowL( *this );

iListBox->ConstructFromResourceL( reader );
