[Qt-interest] aspect-ratio for graphs

[phil prentice]

Sorry Sean
  Finger/Brain trouble...

  Indeed I am trying to use heightForWidth()...See my original mail which has 
a derived object within a layout.  I am cutting it down though and will 
continue to try and get it to work.  If no success I will mail the cut down 
version of my code. If I am successful I will also provide the code.
Thanks for your help
Phil
