Subject: [uDraw(Graph)-Users] uDraw -- is there a way to suspend updates?

Good day everyone:

I have a simulation I am writing that adds a bunch of graph nodes at  
startup time and then shifts to an intermittent add/delete/change  
model. Is there a way to tell the front-end via the API to suspend  
updates to the actual display and then recalculate the graph when I am  
done with the bulk adds? I suspect this would (dramatically) speed up  
my sim-startup without me having to write a bunch of code to aggregate  
all the startup messages and then somehow not aggregate them when in  
update mode. I.E., I want to be lazy ;).

Any thoughts?

unfortunately you can't suspend updates in uDraw(Graph), each API command
is executed immediately. No chance to be lazy in this part of your code. ;-)
