Re: [Repast-interest] Beginner--GUI display object call order

[Chris B. <cbe...@ec...>]

Well, that was fast!  I've made so many discoveries and changes to the 
code I guess I stopped looking for simple things. 

I moved the setXY() out of buildModel() and into buildDisplay() after 
constructing the main objects and the display does work now.  However, 
clicking the Step button produces no effect in the agent behavior, so 
either I'm not calling the right method for updating the display or the 
agent isn't implemented correctly (or something else :).  I'll continue 
to investigate and when the code looks submittable I'll let you know.

Regarding the lack of errors, I'm stuck using Windows ME for the time 
being, and I've noticed a number of instances of strange behavior such 
as widgets not being redrawn correctly, so it's quite possible that 
RePast is throwing the errors but I just don't see them.  When I run the 
old code, the GUI simply hangs.  Ah well, can't let that stop me.

Thanks for your help.

-Chris.
