Thanks for the two suggestions. The Pango::Alignment method doesn't work 
- as I am trying to align the text labels to specific points on the 
screen. I did use it too - to be sure. The best method I found after 
your suggestion was,

void get_pixel_size(int& width, int& height) const

This gives me the dimensions of my Pango::Layout before drawing it to 
the screen - I can use these two dimensions to calculate the best 
positions for my text labels. Many thanks for pointing these functions out.

I just need to figure the symbols out now - it is a scientific 
application. Probably of no use to many people outside of my research 
group and so I can ensure the Symbol font is installed on the systems 
the software will be installed on :)

Thanks for the help,

Marcus
