  After some experiment and reading the Qt code, seems there is no easy way to extend the line height..
  E.g. QPlainTextEdit will show the text with different line height, so I believe I couldn't do it with in Qt.
  So I tried to use a small trick to fill the gap.
  If there is some gap need to be filled, then the code tried to draw some transparent text so the background will be extended to fill the gap. Then draw the real text.
  The solution is hacky though.
