:-) I added this the other day to the article Painting a Page. I paste
it here again:
For justification, you need to know the length of a string. For this you
can use
aFont stringWidthOf: aString at: aFontsize.
Using our example you would write
(Graphics.Fonts.Font fontAt: #Helvetica) stringWidthOf: 'Hello' at: 10.
returning 22.78 which is the width in PostScript points in an unscaled
coordinate system.

For the report layout: is there a way to know the font size when
calculating layout? My understanding is that the report code will have
to deal with word wrap and text justification. I will need to know how
long a string of characters in a given font. For now I'm using estimated
values. It works, but it's not the correct solution.
