Hide text in entry box when i click on it.(GUI using Tkinter in python)

[hmmeera...@gmail.com]

Hello Guys,
Here i am creating a entry box with some text,i need to hide the text when i click on it.
Here is my code

from Tkinter import *
obj = Tk()
b = Entry(obj,width=100)
b.insert(0,"Enter the value to search")
b.pack()
mainloop()

You need to bind a callback function to a mouse event:

import Tkinter as tk

def clear_search(event):
search.delete(0, tk.END)

root = tk.Tk()

search = tk.Entry(root, width=100)
search.insert(0, "Enter the value to search")
search.pack()
search.bind("<Button-1>", clear_search)

root.mainloop()

This will always clear the Entry; you probably want to check if it contains
the initial message first to avoid that the user accidentally loses input.

This is the correct answer for a mouse click. The typical use case
(disappearing placeholder) should also trigger, when somebody uses the
tab key to set the focus to the window. This can be achieved by binding
to the <FocusIn> event instead:

search.bind("<FocusIn>", clear_search)

In addition, repeated clicking does not clear the text then.

Did you look at the exception you get when this runs? It might
possibly be able to point you to the problem, and maybe suggest how
you could resolve it (by importing something, perhaps).

Spot the difference between the identifiers I underlined. If you run
this from the command line, the traceback tells you exactly what is
going on.
