TInt screenWidth = 240 ; // set width as per your requirement.
AknTextUtils::WrapToArrayL(buffer, screenWidth,*font, *iTextArray);
TInt Height = 0; //to set height of label.[[Category:Symbian C++]]
for (TInt i = 0; i < iTextArray->Count(); i++)
{
TInt length = iTextArray->At(i).Length() + 1;
iMultiLineText = iMultiLineText->ReAllocL(iMultiLineText->Length() + length);
iMultiLineText->Des().Append(iTextArray->At(i));
iMultiLineText->Des().Append(_L("\n"));
Height += font->HeightInPixels() + font->AscentInPixels()/2;
}

iLabel->SetTextL(iMultiLineText->Des());

// setting font color to red.
iLabel->OverrideColorL( EColorLabelTextEmphasis, KRgbRed );
