That's not possible. Essentially what you want is to take a click from
one draw command-- [filledpolygon]-- and "map" it or forward it to
another-- [drawnumber]. Scalars don't give you any tools to hook in to
a parent drawing command's widgetbehavior that way.

You could probably do it if you use a field variable to define hotspots
on every 6x6 tile of the rectangle. But you'd also have to constrain
movement of the rectangle by abusing the quanta syntax, something like
(-whatever:whatever)(0:0). That would presumably constrain the field
variable's screen coordinates so that it doesn't move when you
click-drag it. Then use the same field variable for your [drawnumber].
I'm almost finished with some new drawing instructions for data
structures in Pd-l2ork that implement a subset of the svg spec. I've got
some mouseover/mouseout widgetbehaviors working, but still nothing
particularly sophisticated in terms of mapping mouse/keyboard
interaction to field variables.
One possibility is to make the hotspot bbox settable. Or maybe have a
method to forward widgetbehaviors to another drawing command.
