The object of CEikRichTextEditor does not scale

Hello,

I use two objects of CEikRichTextEditor in one window.

iRt1 = new (ELeave) CEikRichTextEditor();
iEditPhraseEdwin->SetContainerWindowL (*this);
iEditPhraseEdwin->ConstructL (CEikEdwin::ENoAutoSelection | CEikEdwin::EReadOnly | CEikEdwin::EAvkonDisableCursor|CEikEdwin::EAvkonEditor );

iRt2 = new (ELeave) CEikRichTextEditor();
iEditPhraseEdwin->SetContainerWindowL (*this);
iEditPhraseEdwin->ConstructL (CEikEdwin::ENoAutoSelection | CEikEdwin::EReadOnly | CEikEdwin::EAvkonDisableCursor|CEikEdwin::EAvkonEditor );

when I switch the phone from portrait mode to landscape mode, those two rich text editors do not scale.

I also use this function to set the size of the rich text editor
void SizeChanged()
{
TInt height = (Size().iHeight) / 2;
TInt width= Size().iWidth;
TPoint edit_origin(0, 0);
TPoint disp_origin(0, height);

iRt1->SetExtent (edit_origin, TSize (width, height));
iRt2->SetExtent (disp_origin, TSize (width, height));
