[PD] Data structure: drawnumbers in an array

mac2k1 Thu, 11 Oct 2012 09:33:31 -0700

Dear List,

I have an issue with a data structure consisting of a rectangle and an array of 
dots, with x/y coordinates and a z value for each dot. I displayed the z value 
with [drawnumber]. See the attached patch.


I can clic and move the dots. However, mouse clics do not seem to reach the 
number area correctly. There seems to be a wrong scaling of mouse coordinates 
when trying to reach numbers nested in arrays. In pd 0.43 vanilla and 0.42.5 
extended.

I remember a behavior of the same kind with objects filled with lots of text 
lines. This one was apparently fixed in pd 0.43. 

I wish I could enter my numbers by mouse or keyboard, but for now I can handle 
them via the data properties window.
