who is in charge about coordinating tcl/tk and pd?
there is no-one in charge
guess that an option to query objects for their parameters would really speed up and enhance interface design in pd. something like "; myhslider get_width"
i think this reflective nature for objects is in the design spec for DesireData (look for the PS published for Piksel '05, or the earlier one for PD-C 1.0). im pretty sure it hasnt reached the point of stability that it is being considered to be rolled into the the mainline version of PD maintained by the original author. one thing that could help change that is for you to test it out.. it is in the devel_0_39 branch of CVS
a nice interactive property inspector can be done up in 10 lines of Tk..
in desireData, the object properties are stored in a hash with keys like $_(objectID:property), in ixpd, theyre stored in a TCL dictionary
if what you want is the ability to query any object (including the core, non-GUI ones) for their current state, and set any properties via an inspector, this doesnt quite exist (although with the class inspector from impd you could probably get close to at least knowing what stuff is changeable, without digging thru the help patches or object source)
pd is still a work in progress...
