gtk:cell-renderer-text-set-fixed-height-from-font (renderer rows)

renderer -- a gtk:cell-renderer-text object
rows -- an integer for the number of rows of text each cell renderer is allocated, or -1

Sets the height of a renderer to explicitly be determined by the font and padding properties 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 a cell is too slow, that is, a massive number of cells displayed. If the rows argument is -1, then the fixed height is unset, and the height is determined by the properties again. The gtk:cell-renderer-text implementation is deprecated since 4.10. Please do not use it in newly written code.
