How to set default text for a Tkinter Entry widget

Question

How do I set the default text for a Tkinter Entry widget in the constructor? I checked the documentation, but I do not see a something like a "string=" option to set in the constructor?

There is a similar answer out there for using tables and lists, but this is for a simple Entry widget.

Solution 1

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

Solution 2

For me,

Entry.insert(END, 'your text')

didn't worked.

I used Entry.insert(-1, 'your text').

Thanks.
