[PYTHONMAC-SIG] MacSpeech

[Mark Alford]

I'm sorry about my earlier "missent" attempt.
Please ignore it.

Here is a clearer description of my problem.


I've been having a problem using Tkinter and MacSpeech together,
on a PowerPC laptop. I'm running Mac System 8, with Python 1.5b3.
I've created a script that displays the problem (see below).

On the laptop, this script invariably dies
the *second* time I run it. How it dies depends on how much
memory is allocated to Python. Usually it freezes up
the whole machine, or gives "error type 112".

I'd be very grateful if anyone else could verify that this happens
(and perhaps suggest a cure...)
The laptop is a Powerbook 3400c, with 80M of RAM.

#----------- Example script, dies on *second* running -----------
from Tkinter import * 
import macspeech

class MacSpeaker:   # taken and simplified from grail.py in Mac speech demo
  def __init__(self):
    self.voices = []
    self.nvoices = macspeech.CountVoices()
    self.curvoice = 1

  def _newvoice(self):
    vd = macspeech.GetIndVoice(self.curvoice)
    sc = vd.NewChannel()
    self.curvoice = self.curvoice + 1
    if self.curvoice > self.nvoices:
      self.curvoice = 1
    return sc

  def newvoices(self, n):
    self.voices = []
    for i in range(n):
      self.voices.append(self._newvoice())

                   # The class for the main window:
class  Box(Frame): 
    def __init__(self, parent=None): 
        Frame.__init__(self, parent) 
        self.speaker = MacSpeaker()           # open up the speaker
        nv = self.speaker.nvoices
        print nv

              # Here is where it freezes upon the second running if nv is 22, 
              # the full number of voices available
# *******>>>>>>
        self.speaker.newvoices(nv)


bb = Box()
bb.mainloop()
#--------------- End of example script --------------------
