Re: [Jython-users] type conversions to Graphics2D

[Mark R. <blo...@ho...>]

cheers, I had intended to send it to the list, but I just cocked it all up 
;)

What I am actually trying to do is in order to gain some familiarity with 
jython I am rewriting a java prog I have in a book in jython. In the java 
example it was typed exactly as in my first example i.e.

g2 = (Graphics2D)g

it seems to work in java...guess I will have to keep tinkering to work out 
how jython wants to do it
