I can't comment on the PMW framework and I haven't tried it in
Python Tix but the Tcl documents claim Tix does a similar thing.
Certainly insofar as it provides a framework for creating your
My Tcl/Tk Nutshell book says:
"Tix adds an object oriented (AG: ie. to Tcl/Tk) framework for
new widget types from existing widget types. Instances of these
new widget types are called mega-widgets. Tix includes over
40... and several commands for designing new ones..."
The main creation commands I see are tixWidgetClass, tixCallMethod,
tixChainMethod. There are maybe half a dozen others.
A quick look in Python Tix reveals a TixWidget class. But the
other commands are not obvuiously available - but they may
be hidden as methods of something else...

It can do the forwarding of methods but I can't see any validators
It would be interesting to do a bit of comparison, if only there were
some decent documents for Python Tix! :-(
