Entry
widgets seem only to deal with single line text. I need a multiline entry field to type in email messages.
Anyone has any idea how to do that?
You could use the Text widget:
from tkinter import *
root = Tk()
text = Text(root)
text.pack()
root.mainloop()
Or with scrolling bars using ScrolledText:
from tkinter import *
from tkinter.scrolledtext import ScrolledText
root = Tk()
ScrolledText(root).pack()
root.mainloop()
