How to connect a variable to Entry widget?
I think you want something like this. In the example below, I created a variable myvar
and assigned it to be textvariable
of both a Label
and Entry
widgets. This way both are coupled and changes in the Entry widget will reflect automatically in Label.
You can also set trace on variables, e.g. to write to stdout.
from tkinter import *root = Tk()root.title("MyApp")myvar = StringVar()def mywarWritten(*args): print "mywarWritten",myvar.get()myvar.trace("w", mywarWritten)label = Label(root, textvariable=myvar)label.pack()text_entry = Entry(root, textvariable=myvar)text_entry.pack()root.mainloop()
