font actual font ?-displayof window? ?option?
Returns information about the the actual attributes that are obtained when font is used on window 's display; the actual attributes obtained may differ from the attributes requested due to platform-dependant limitations, such as the availability of font families and pointsizes. font is a font description; see FONT DESCRIPTIONS below. If the window argument is omitted, it defaults to the main window. If option is specified, returns the value of that attribute; if it is omitted, the return value is a list of all the attributes and their values. See FONT OPTIONS below for a list of the possible attributes.
Question: what kind of paramater is given to the -displayof argument? A Tk window name ?
For instance, if I say:
button .b -font fixed font actual -dislayof .b
I see an error. However, I seem to get somem sort of answer when I say:
font actual .b
Is the results the real information, or the info that Tk uses, then deviates from until it finds a best match?
