Hello,

I am drawing qgraphicscenes using pyqt and different elements in it. One of these \
elements is a qgrapchissimpletextitem, where I use a monospaced font (Courier, size \
12) printing a long string with capital letters. Below this string I'd like to show a \
histogram, building a qgraphicsrectitem for each letter of the string above. For \
doing this I need to well position my rectangles below each letter. This was possible \
in Linux systems, where I could set a exact width to each rectangle.

Now I open the whole thing in Mac OSX Snow Leopard and the monospaced font is not \
shown the same way, So I had a look into fontmetrics for this font, I used the \
charWidth function, which returns me 8 pixels for one char of Courier, 12. Still my \
rectangles below don't fit. I tried to use the width function, without success \
(returns 0). 

Basically I cannot manage to fit the width of my rectangles to the width of my \
characters of my string....did somebody experienced the same issues. It worked fine \
on openSuse, but is a headache in Mac. 

I know that instead of using a String for the sequence I could print every character \
as seperate object, however this would overload the scene and I don't see the point \
if monospaced fonts are available. 

Thanks in advance.

Peter
