tkinter Frame does not detect event

Question

Why tkinter.Frame in python does not work with someframe.bind("<Motion>", somefunc)? In this case somefunc does not get executed. Can someone please explain this to me?

code: self.frame.bind("<Motion>", tippy.update)

If I bind this to for example tkinter.Label, everything works as expected. Code is executed.

EDIT: I thought that if I have tkinter.Label in tkinter.Frame and if I hover the mouse over the tkinter.Label, it will get executed because its in the tkinter.Frame. However tkinter.Frame detects movement only if there is no other widget in the place. Basically i thought that tkinter.Frame space is not overwrited with tkinter.Label.

We'll need more information to be able to answer the question. Please edit your post to include the piece of code that doesn't work as expected. — Daniel, Oct 08 '17 at 08:57
The frame _does_ work with the `` event. Please show an [mcve] that illustrates why you think it doesn't. — Bryan Oakley, Oct 08 '17 at 14:05
@SolarFactories: focus only related to keyboard events, not mouse events. — Bryan Oakley, Oct 08 '17 at 14:05

The below code demonstrates that the <Motion> event does work with a Frame widget in tkinter:

from tkinter import *

root = Tk()

def callback(*args):
    print("Motion detected")

frame = Frame(root, width=100, height=100)

frame.bind("<Motion>", callback)

frame.pack()

root.mainloop()

If you can provide an MCVE we can try and help you through whatever problem you're having.
