ТТК.Treeview-не удается изменить высоту строки

Я использую ttkcalendar.py где можно найти в этой ссылке.

я адаптировал его для использования в Python 3.3

в основном то, что я пытаюсь сделать, это ввести этот виджет календаря в мое приложение Tkinter, которое отлично работает, и там нет проблем.

проблемы, которые я хочу преодолеть:

1. как изменить размер шрифта календаря (месяц, дни и даты) -завершено
2. как сделать Я меняю выбранную дату, чтобы она шла bold. - завершено
3. как я могу изменить высоту строк treeview как в попытках предыдущего, размер шрифта может быть увеличен, но высота строки не увеличивается с размером шрифта. - ВСЕ ЕЩЕ ЖДЕМ ПОМОЩИ

спасибо заранее.
