Hi Friend.This is my code for Status bar.Even though i didn’t get any error or warning. I had failed to obtain the status bar. But my Widget is getting opened with empty in it.Can any one please help me in this aspect.

Thank you

It’s there; it’s just very small because none of the widgets requested much space.
If you put some text in the Label, or gave root a geometry, it would be easier to see:

import Tkinter as tk
class StatusBar(tk.Frame):   
    def __init__(self, master):
        tk.Frame.__init__(self, master)
        self.variable=tk.StringVar()        
        self.label=tk.Label(self, bd=1, relief=tk.SUNKEN, anchor=tk.W,
                           textvariable=self.variable,
                           font=('arial',16,'normal'))
        self.variable.set('Status Bar')
        self.label.pack(fill=tk.X)        
        self.pack()

root=tk.Tk()
d=StatusBar(root)
root.geometry('300x100')
root.mainloop()

By the way, to allow the text inside the label to change, use a tk.StringVar.
Calling self.variable.set(...) will change the label’s text. And to clear it just call self.variable.set('').
