Now I want to be able to calculate the optimal width of the view so
that the entire text is visible.
This worked wonders for me:

This also does not solve my problem.
Getting the height of a text for a given width is easy and I've done
that countless times.
Also getting the width of a string (layed out in one line if it has no
newlines) is no problem.
But I have a different problem. I try to give an easier explanation of
my problem:
I have a text view that has a height that can hold three lines of
text. Now I have one long string (without newlines). When putting this
string into the text view, the text is automatically wrapped around.
But maybe - for the initial width of the view - it will need four (or
more) lines instead of just three. Now I want to calculate the optimal
(minimum) width of the text view, to that the string is wrapped around
in just three (or less) lines.
In the meantime I guess I have the solution. I don't think that there
is really a way in Cocoa or Quartz that solves this problem. So I
really have to "try" different widths, let the layout manager layout
the text and see how much lines it needs. So I can do a "binary
search" to get an ideal width.
Even if Cocoa or Quartz would have a method for calculating the width,
it would internally also have to do such a binary search. I don't
think that it's possible to calculate the perfect width in one step.
So I just do it myself and it works quite well.
Thanks for your attention,
Mani
