Re: Changing the graph color at run time

[Roland Bock <box2OO6 eudoxos de>]

Hi Nisha,

I see no reason why this should not work in principle.

Remarks:

a) To me (not knowing your application) it seems a little strange that 
you want to put each graph into a different box? Your introduction 
sounds different.

b) If p and i are shared among the threads, you need some thread 
synchronization. Otherwise you could have situations where i does not 
stay the same during that code sequence


Regards,

Roland
