GdkFont::height
int height(string text_string);
The return value of height() is
arrived at by summing the values of ascent and
descent returned by
extents() and relating to the
current string.
Under win32, this is a bogus value. Add the values returned by the
GdkFont properties
ascent and
descent to get the value of the
font's height.
The value of the height is the line-height, given in pixels, and
represents the logical space required by a line. If you are using
this measurement to calculate the size of a text box, you will need to
add 6 pixels to the total to allow for the borders of the text widget.
