All,
	I am using the AppShell framework for a test application and am
trying to get my callbacks working correctly.  I have the AppShell
application which makes a call to a Pmw.ComboBoxDialog class.  How do I
need setup my callbacks for my AppShell application??  Yes I'm new to
Pmw :)

My call in the AppShell application:


def viewArmorLibrary(self):
    """Creates Tkinter listbox to select which library, Armor or
Device"""
    ComboBoxDialog.ComboBoxDialog(None, 'armors')


My ComboBoxDialog class:


#!/usr/bin/env python

from Tkinter import *
import Pmw
import xml.sax
import XBeepXmlReader

class ComboBoxDialog(Pmw.Dialog):
    # Dialog window with simple combobox.
   =20
    # Dialog window displaying a list and entry field and requesting
    # the user to make a selection or enter a value

    def __init__(self, *args, **kw):
        #define which library to view, Armor or Device
        self.library =3D args[1]
        self.library_var =3D ""
        self.changed =3D BooleanVar()
        self.instructions =3D 'Double click value to select:\n'
       =20
        if self.library =3D=3D 'armors':
            self.label =3D 'Armor'
        elif self.library =3D=3D 'devices':
            self.label =3D 'Device'
           =20
        # Define the megawidget options.
        INITOPT =3D Pmw.INITOPT
        optiondefs =3D (
            ('borderx',    10,              INITOPT),
            ('bordery',    10,              INITOPT),
        )
        self.defineoptions(kw, optiondefs)

        # Initialise the base class (after defining the options).
        Pmw.Dialog.__init__(self, args[0])
   =20
        # Create the components.
        interior =3D self.interior()
   =20
        aliases =3D (
            ('listbox', 'combobox_listbox'),
            ('scrolledlist', 'combobox_scrolledlist'),
            ('entry', 'combobox_entry'),
            ('label', 'combobox_label'),
        )
        self.parser =3D xml.sax.make_parser()
        self.handler =3D XBeepXmlReader.XBeepXmlReader()
        self.parser.setContentHandler( self.handler )
       =20
        #Need to check to see if file exists
        if self.library =3D=3D 'armors':
            file =3D "XBEEP/BEEP_Armors.xml"
        elif self.library =3D=3D 'devices':
            file =3D "XBEEP/BEEP_Devices.xml"
        else:
            print 'Cannot find the library...'
            sys.exit(1)
           =20
        self.parser.parse(file)

        self._combobox =3D self.createcomponent('combobox',
            aliases, None,
            Pmw.ComboBox, (interior,),
            labelpos =3D 'n',=20
            label_text =3D self.instructions + self.label + ':',
            scrolledlist_items=3Dself.handler.names,
            scrolledlist_dblclickcommand =3D self.getValue,
            dropdown =3D 0,
        )
        self._combobox.pack(side=3D'top', expand=3D'true', =
fill=3D'both',
            padx =3D self['borderx'], pady =3D self['bordery'])
       =20
        # Check keywords and initialise options.
        self.initialiseoptions(ComboBoxDialog)
       =20
    def myDestroy(self):
        print 'Here...'
        self.destroy()
       =20
    def getValue(self):
        self.library_var =3D self._combobox.get()
        print '%s library value selected: %s' % (self.label,
self.library_var)
        self.myDestroy()

Pmw.forwardmethods(ComboBoxDialog, Pmw.ComboBox, '_combobox')


Thanks in advance, =20
