Summary: scaling and multiple displays

Initial Comment:
Hi Brian,

Since no one seems to have an answer to your question
(regarding that it is not the first time you ask this
question), I share my experience on this, even if I
don't really have a solution to your problem.

I have the same problem as you have, using multiple
displays at the same time.
The problem seems not to be related with the particular
kind of grids you use, since i'm using Object2DGrids
and MultiObject2DGrids.

I think it is a problem with the diaplays. It seems
like the problem occurs when converting mouseclick
coordinates to actual grid coordinates. After some
testing, I came to the conclusion that the scaling
factors are the same for all displays, meaning that
when you have multiple displays with different sizes,
the conversion uses the scaling factor of one daisplay
even when converting coordinates for others, instead of
using the appropriate scaling factors for each display.

My "solution" to this is to make all displays the same
size by dragging the frames.
Since the sizes keep the same after restarting RePast
when you don't add or remove displays in the code, it's
not as tedious as one might be afraid.

But it's still not very elegant...
So I would appreciate a more profound answer to this
question by someone with a deeper understanding of the
displaying mechanisms.

Hope this was somehow helpful.

Subject: [Repast-interest] Problem with Probeable Agents
 
Hello all!

For some time I have been struggling with an apparent
scaling problem between my grid and my display surface.  

I "believe" I have verified with print statements that
my agents are accurately reflected on the display
surface but when I try to probe some of the agents,
either the wrong agent is displayed (easily detected
since the agent states do not match the displayed
states) or nothing is displayed (which usually happens
in the lower right section of the display surface).

Somehow, it seems like the underlying grid and display
surface are out of scale.  Incidentally, I have
returned to the defaults for cell depth, health, and
width and am using just a single Object2DTorus instead
of a MultiObject2DTorus but I still cannot correct the
problem.  

Any suggestions would be greatly appreciated!

Thanks,
Brian
