hey list, Jonathan.
You start with a struct:[struct foo float x float y canvas a b] Then create a scalar from this struct. The scalar will have an "x" value, a "y" value, and a canvas "a" which gets filled with the contents of an abstraction "b.pd" that is somewhere in Pd's search path. Now here's the neat thing-- inside the newly instantiated "b.pd" you can do this: [loadbang]|[field x]|[print x]
imagine you have a drawing instruction like this:[draw rect 0 0 20 20]
When you create the scalar you get a little black box on a canvas. With a canvas field like I described, you can right-click the scalar and choose "Open" to show a canvas window.
while trying to create [struct foo float x float y canvas a b], i get: canvas: no such type, using pd 0.46.6 what am I missing?
