[Plplot-devel] Can we get the plframe widget working with python/Tkinter now?

[Alan W. I. <ir...@be...>]

The only limitation that I am aware of for the normal python build is we are
not yet able to use the plframe widget with python/Tkinter.  I would like
to see this limitation removed.

Geoffrey, this note is a reminder that our tkdemos.tcl and tcldemos.tcl
examples now work under tclsh and wish using dynamic loading.  In the past
you have said that was a prerequisite for getting plframe to work with
python/Tkinter.

I just tried to get the old set of python scripts (pytkdemo, Plframe.py, and
the old x??.py examples that are called by pytkdemo) to work.  Obviously
bit-rot has set in, but by doing some obvious hacks (pl --> plplot, etc.) I
got this far using a test version of pytkdemo called test.py:

./test.py
Building the Python Tk demo application main window.
Traceback (most recent call last):
  File "./test.py", line 174, in ?
    demo = DemoApp()
  File "./test.py", line 18, in __init__
    s.create_widgets()
  File "./test.py", line 27, in create_widgets
    s.plf = PlXframe(s, width="17c", height="17c" )
  File "./Plframe.py", line 127, in __init__
    s.plf = Plframe( s, kw )
  File "./Plframe.py", line 37, in __init__
    Widget.__init__( self, master, 'plframe', cnf, kw )
  File "/usr/lib/python2.1/lib-tk/Tkinter.py", line 1756, in __init__
    self.tk.call(
TclError: invalid command name "plframe"

So what is the next step (perhaps some additional special wrapper functions
need to be written for plplot_widgetmodule.c?) to get the plframe widget
working in an environment where anything from the plplplot libraries can be
dynamically loaded into python/Tkinter?
