I am trying to figure out how to change widgets in Python/TK so that I can clear and refill listboxes also so that I can change the state of Buttons and other objects.  here is some example code.

from Tkinter import *

class Delivery:
    def __init__(self, master):
        frame = Frame(master, width=500, height=400, bd=1)
        frame.pack()

      self.mbar = Frame(frame, relief = 'raised', bd=2)
      self.mbar.pack(fill = X)

      # Create File menu
      self.filebutton = Menubutton(self.mbar, text = 'File')
      self.filebutton.pack(side = LEFT)

      self.filemenu = Menu(self.filebutton, tearoff=0)
      self.filebutton['menu'] = self.filemenu

      # Populate File menu
      self.filemenu.add('command', label = 'Exit', command = self.quit)

      # Create  help menu
      self.helpbutton = Menubutton(self.mbar, text = 'Help', )
      self.helpbutton.pack(side = RIGHT)

      self.helpmenu = Menu(self.helpbutton, tearoff=0)
      self.helpbutton['menu'] = self.helpmenu

      # Populate help menu
      self.helpmenu.add('command', label = 'help', command = self.stub)

        iframe1 = Frame(frame, bd=2, relief=SUNKEN)
        Button(iframe1, text='Button').pack(side=LEFT, padx=5)
        Checkbutton(iframe1, text='CheckButton').pack(side=LEFT, padx=5)

        v=IntVar()
        #Radiobutton(iframe1, text='Button', variable=v,
        #            value=3).pack(side=RIGHT, anchor=W)
        #Radiobutton(iframe1, text='Dio', variable=v,
        #            value=2).pack(side=RIGHT, anchor=W)
        #Radiobutton(iframe1, text='Ra', variable=v,
        #            value=1).pack(side=RIGHT, anchor=W)
        #iframe1.pack(expand=1, fill=X, pady=10, padx=5)

        iframe2 = Frame(frame, bd=2, relief=RIDGE)
        Label(iframe2, text='OFFENBACHERS Delivery Scheduling System').pack()
        t = StringVar()
        #Entry(iframe2, textvariable=t, bg='white').pack(side=RIGHT, padx=5)
        #t.set('Entry widget')
        iframe2.pack(expand=1, fill=X, pady=10, padx=140)

        dframe2 = Frame(frame, bd=2, relief=RIDGE)
        Label(dframe2, text='ENTER TICKET NUMBER:').pack(side=LEFT, padx=5)
        t = StringVar()
        Entry(dframe2, textvariable=t, bg='white').pack(side=LEFT, pady=10)
        t.set('')
        Button(dframe2, text="SUBMIT",command = self.submitticket).pack(side=LEFT)
        dframe2.pack(expand=1, fill=X, pady=15, padx=140)

        zframe2 = Frame(frame, bd=2, relief=RIDGE)
        Label(zframe2, text='ENTER ZIP CODE:').pack(side=LEFT, padx=5)
        t = StringVar()
        Entry(zframe2, textvariable=t, bg='white').pack(side=LEFT, pady=10)
        t.set('')
        Button(zframe2, text="SUBMIT").pack(side=LEFT)
        zframe2.pack(expand=1, fill=X, pady=5, padx=140)

        iframe3 = Frame(frame, bd=2, relief=GROOVE)
        listbox = Listbox(iframe3, state=DISABLED, height=4, width=30)
        scroll = Scrollbar(iframe3, command=listbox.yview)
        listbox.configure(yscrollcommand=scroll.set)
        for item in ['January','February','March','April','May','June','July','August','September','October','November','December']:
            listbox.insert(END, item)
        scroll.pack(side=LEFT, fill=Y)
        listbox.pack(fill=X)
        iframe3.pack(expand=1, fill=X, pady=10, padx=140)
       
        iframe4 = Frame(frame, bd=2, relief=GROOVE)
        listbox = Listbox(iframe4, state=DISABLED, height=15, width=30)
        scroll = Scrollbar(iframe4, command=listbox.yview)
        listbox.configure(yscrollcommand=scroll.set)
        for item in ['January','February','March','April','May','June','July','August','September','October','November','December']:
            listbox.insert(END, item)
        scroll.pack(side=LEFT, fill=Y)
        listbox.pack(fill=X)
        iframe4.pack(expand=1, fill=X, pady=10, padx=5)

        f1=Frame(frame, width=300, height=10)
        Button(f1, text="SCHEDULE DELIVERY", bg='gray75', state=DISABLED).pack(side=LEFT, padx=40)
        f1.pack()
       
        iframen = Frame(frame, bd=2, relief=FLAT)
        Message(iframen, text='', width=300,
                relief=SUNKEN).pack(fill=X, padx=5)
        iframen.pack(expand=1, fill=X, pady=22, padx=5)

    def quit(self):
        root.destroy()

    def stub(self):
        pass

    def submitticket(self):
        pass
     
root = Tk()
root.option_add('*font', ('verdana', 10, 'bold'))
all = Delivery(root)
root.title('Delivery Scheduling')
root.mainloop()



In the Above example I wouldl like to make def submitticket change the iframe3 to state=Normal and as well I would like it to Clear the Items that are there and Add new ones to that listbox.....  

Thanks in advance

Here you go.  The changes are:

 o Keep references to your listboxes, as self.listbox1 and self.listbox2
 o Don't disable the listboxes until after you've populated them
 o In submitticket, enable the listbox, delete the items, and add new ones.

from Tkinter import *

class Delivery:
    def __init__(self, master):
        frame = Frame(master, width=500, height=400, bd=1)
        frame.pack()

        self.mbar = Frame(frame, relief = 'raised', bd=2)
        self.mbar.pack(fill = X)

        # Create File menu
        self.filebutton = Menubutton(self.mbar, text = 'File')
        self.filebutton.pack(side = LEFT)
       
        self.filemenu = Menu(self.filebutton, tearoff=0)
        self.filebutton['menu'] = self.filemenu

Here you are.  self.listbox1.bind('<ButtonRelease>', self.onselect) is the "how the events work and such" piece!

from Tkinter import *

class Delivery:

        frame = Frame(master, width=500, height=400, bd=1)
