Pass text variables to Labels in Tkinker GUI?

[2inshix]

I'm trying to put together this GUI, it's my first attempt. It's mostly a collage of code I put together from samples I found here and there.

So, far so good, except I can't seem to be able to figure out how to pass "text variables" from an array to labels.

#If you go to def printLabels(sel f), and def on_move(), you will see what I mean:),

Thanks a million. (I'm just learnig to #program, sorry about the mess!)

#! /usr/bin/env python
# -*- coding: cp932 -*-
from Tkinter import *
import tkMessageBox

#If you go to def printLabels(self) you will see my #question, thanks a million. (I'm just learnig to #program, sorry about the mess!)

There are two ways to update your labels. Use widget method w.config() to reassign a new label in your on_click() method. Alternatively, create Tkinter.StringV ar objects and configure your Tkinter.Label objects with keyword textvariable instead of text and assign it to the appropriate variable. Reassign the value of the variables using StringVar method set() in your on_click() method.

Here's an example using a Tkinter.StringV ar in combination with a Tkinter.Label.

textFont1 = ("Arial", 16, "bold")

class Clock(Tkinter.Frame):

        master.config(menu=menubar)
        optionsMenu = Tkinter.Menu(tearoff=0)
        menubar.add_cascade(label="Options", menu=optionsMenu)
        optionsMenu.add_command(label='Print', command=self.print_value)
        optionsMenu.add_command(label='Stop', command=self.destroy)
        optionsMenu.add_command(label='Restart', command=self.start)
        optionsMenu.add_command(label='Quit', command=master.destroy)
        self.start()

    def start(self):
        Tkinter.Frame.__init__(self, self.master)
        self.pack(fill=BOTH, expand=1)
        self.clockVar = Tkinter.StringVar(self.master)
        self.clockLabel = Tkinter.Label(self, textvariable=self.clockVar,
                                        relief="raised", font=textFont1,
                                        bd=3,
                                        bg='#ffffff000',
                                        fg="#000000fff",
                                        activebackground = "#000000fff",
                                        activeforeground = "#ffffff000",

                                        pady=3)
        self.clockLabel.pack(fill=BOTH, expand=1)
        self.run()

    def run(self):
        timeStr = time.strftime("%A, %b %d, %Y\n%I:%M:%S %p\n%Z")
        # 24 hour clock
        #timeStr = time.strftime("%A, %b %d, %Y\n%X\n%Z")
        if timeStr != self.clockVar.get():
            self.clockVar.set(timeStr)
        self.after(200, self.run)

    def print_value(self):
        print self.clockVar.get()

thanks bvdet I think I understand but I won't know for sure until I give it a shot. I'll let you know how it went!

Cheers,

happy holidays.

Ok!

I tried it and it worked right away!

I'm a happy man!

Happy holidays everyone!
