/**

*  CDialer class.

*

*  @lib dialer.lib

*  @since Series60_5.0

*

*  Description:

*   Dialer is used in two applications, telephony and video telephony.

*

*   In Telephony dialer handles number (number/sip address) input from 

*   user via touch screen, VKB or hw keyboard (ITU-T and QWERTY).

*

*   From host application dialer requires:

*   - View/container as CCoeControl

*

* 

*  Usage:

*

    // Hide status pane.

    if ( Layout_Meta_Data::IsLandscapeOrientation() )

        {

        static_cast<CAknAppUi*>( CEikonEnv::Static()->EikAppUi())->

            StatusPane()->MakeVisible( ETrue);

        }

    else

        {

        static_cast<CAknAppUi*>( CEikonEnv::Static()->EikAppUi())->

            StatusPane()->MakeVisible( EFalse );

        }

    // Calculate dialer area:

    TRect screenRect( 

        TPoint( 0, 0 ), 

        iCoeEnv->ScreenDevice()->SizeInPixels() );   

    TAknLayoutRect appRect;

    appRect.LayoutRect( 

        screenRect, AknLayout::application_window( screenRect );

    TAknLayoutRect mainRect;

    mainRect.LayoutRect( 

        appRect.Rect(), 

        AknLayout::main_pane( appRect.Rect(), 0, 1, 0 ) );

    TRect mainPane( mainRect.Rect() );

    // Reduce the space that CBA need from the rect

    CEikButtonGroupContainer cba = iEikEnv.AppUiFactory()->Cba();

    TRect mainPane( aRect );    

    cba->ReduceRect( mainPane );

    // Create dialer from container (CCoeControl) that created

    // dialer window (CreateWindowL).

*  In telephony dialer:

    // Create dialer.

    CDialer* dialer = CDialer::NewL( *this, aDialerArea );

    // Open dialer

    // Open and show dialer

    iDialer->CreateNumberEntry();

    // methods in MNumberEntry are available to contol dialer and

    // get/set text in number entry.

    // Close dialer

    iDialer->RemoveNumberEntry( );

    // Delete dialer

    delete dialer;
