Calculate Line Height

Is there a possibility to calculate the estimated line height before a TRichViewEdit will be filled with data (pure text, no tables, images aso)?

You can measure a height of a text item by applying its font to some canvas, then calling Canvas.TextHeight.
To apply a style, call
RVStyle.ApplyStyle(Canvas, StyleNo, rvbdUnspecified, False, True, nil, False, False), where StyleNo = RichViewEdit.GetItemStyle(ItemNo), where ItemNo is an index of the text item.
