How to capture events on tkinter child widgets?

In the following block, clicking on a_frame triggers the event handler on_frame_click, but clicking on a_label which is a child of a_frame does not. Is there a way to force a_frame to trap and handle events which originated on it's children (preferably with out having to add handlers to the children directly)? I am using Python 3.2.3.

import tkinter

def on_frame_click(e):
    print("frame clicked")

tk = tkinter.Tk()
a_frame = tkinter.Frame(tk, bg="red", padx=20, pady=20)
a_label = tkinter.Label(a_frame, text="A Label")
a_frame.pack()
a_label.pack()
tk.protocol("WM_DELETE_WINDOW", tk.destroy)
a_frame.bind("<Button>", on_frame_click)
tk.mainloop()
events tkinter python

Depending on what you're trying to do, you could bind everything

print(a_label.bindtags())  # ('.!frame.!label', 'Label', '.', 'all')

tk.bind_class('.', "<Button>", on_frame_click)
