# Method GTK2.CellRendererText()->set_fixed_height_from_font()

Method set_fixed_height_from_font

  `GTK2.CellRendererText set_fixed_height_from_font(int number_of_rows)`

Description

  Sets the height of a renderer to explicitly be determined by the "font" and "y_bad" property set on it. Further changes in these properties do not affect the height, so they must be accompanied by a subsequent call to this function. Using this function is unflexible, and should really only be used if calculating the size of cell is too slow (i.e., a massive number of cells displayed). If number_of_rows is -1, then the fixed height is unset, and the height is determined by the properties again.
