Step 1: Supporting all necessary languages

File CYrRss.l01:

// English language support
 
#define lb_item1 "\tItem1\t"
#define lb_item2 "\tItem2\t"
#define lb_item3 "\tItem3\t"
#define lb_item4 "\tItem4\t"
#define lb_item5 "\tItem5\t"
#define lb_item6 "\tItem6\t"
#define lb_item7 "\tItem7\t"
#define lb_item8 "\tItem8\t"
#define lb_item9 "\tItem9\t"

File CYrRss.l16:

// Russian language support - russian text should be saved in UTF 8 !
CHARACTER_SET UTF8
 
#define lb_item1 "\tЭлемент1\t"
#define lb_item2 "\tЭлемент2\t"
#define lb_item3 "\tЭлемент3\t"
#define lb_item4 "\tЭлемент4\t"
#define lb_item5 "\tЭлемент5\t"
#define lb_item6 "\tЭлемент6\t"
#define lb_item7 "\tЭлемент7\t"
#define lb_item8 "\tЭлемент8\t"
#define lb_item9 "\tЭлемент9\t"

Step 2: Defining listbox in project resources

File CYrRss.rss:

CHARACTER_SET UTF8
 
#ifdef LANGUAGE_01
#include "CYrRss.l01"
#endif
 
#ifdef LANGUAGE_16
#include "CYrRss.l16"
#endif
 
...
 
RESOURCE LISTBOX r_list_box
    {
        flags = EAknListBoxSelectionList;
        array_id= r_list_box_item_array;
    }
 
RESOURCE ARRAY r_list_box_item_array
    {
    items =
        {
        LBUF { txt = lb_item1;},
        LBUF { txt = lb_item2;},
        LBUF { txt = lb_item3;},
        LBUF { txt = lb_item4;},
        LBUF { txt = lb_item5;},
        LBUF { txt = lb_item6;},
        LBUF { txt = lb_item7;},
        LBUF { txt = lb_item8;},
        LBUF { txt = lb_item9;},
        };
    }

Step 3: CYrContainer.h

• Open your CYrContainer.h file.
  
• Inlcude entries for required header files.

#include <aknlists.h> // For List Box
#include <barsread.h> //For Resource Reader

• Add function which will be needed for getting Key response.

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

• Declare object of Listbox:

private: // data
    // ..
    CAknSingleStyleListBox* iListBox;

• Define in mmp-file library:

LIBRARY bafl.lib

Step 4: CYrContainer.cpp

• Open your "CyrContainer.cpp" file.
• Inlcude an additional entry for .rsg file. Like:

#include <YrListBox.rsg>

• Now in the ContructL() function of your CYrContaner.cpp file:

void CYrContainer::ConstructL(const TRect& aRect)
    {
    CreateWindowL();
 
    iListBox= new (ELeave) CAknSingleStyleListBox();
    iListBox->SetContainerWindowL(*this);
 
    TResourceReader rr;
    iCoeEnv->CreateResourceReaderLC(rr, R_LIST_BOX);
    iListBox->ConstructFromResourceL(rr);
    iListBox->CreateScrollBarFrameL(ETrue);
    iListBox->ScrollBarFrame()->SetScrollBarVisibilityL(CEikScrollBarFrame::EOn, CEikScrollBarFrame::EAuto);
 
    CleanupStack::PopAndDestroy();//rr
 
    SetRect(aRect);
    ActivateL();
    }
 
void CYrContainer::SizeChanged()
    {
    iListBox->SetExtent(TPoint(0,0), iListBox->MinimumSize() );
    }
 
 
TInt CYrContainer::CountComponentControls() const
    {
    return 1; // return number of controls inside this container
    }
 
CCoeControl* CYrContainer::ComponentControl(TInt aIndex) const
    {
    switch ( aIndex )
        {
        case 0:
            return iListBox;
        default:
            return NULL;
        }
    }
 
TKeyResponse CYrContainer::OfferKeyEventL(const TKeyEvent &aKeyEvent, TEventCode aType)
    {
    return iListBox->OfferKeyEventL(aKeyEvent, aType);
    }
