Answer 1

The events <FocusIn> and <FocusOut> are what you want. Run the following example and you'll see you get focus in and out bindings whether you click or press tab (or shift-tab) when focus is in one of the entry widgets.

from Tkinter import *

def main():
    global text

    root=Tk()

    l1=Label(root,text="Field 1:")
    l2=Label(root,text="Field 2:")
    t1=Text(root,height=4,width=40)
    e1=Entry(root)
    e2=Entry(root)
    l1.grid(row=0,column=0,sticky="e")
    e1.grid(row=0,column=1,sticky="ew")
    l2.grid(row=1,column=0,sticky="e")
    e2.grid(row=1,column=1,sticky="ew")
    t1.grid(row=2,column=0,columnspan=2,sticky="nw")

    root.grid_columnconfigure(1,weight=1)
    root.grid_rowconfigure(2,weight=1)

    root.bind_class("Entry","<FocusOut>",focusOutHandler)
    root.bind_class("Entry","<FocusIn>",focusInHandler)

    text = t1
    root.mainloop()

def focusInHandler(event):
    text.insert("end","FocusIn %s\n" % event.widget)
    text.see("end")

def focusOutHandler(event):
    text.insert("end","FocusOut %s\n" % event.widget)
    text.see("end")


if __name__ == "__main__":
    main();

Answer 2

This isn't specific to tkinter, and it's not focus based, but I got an answer to a similar question here:

Detecting Mouse clicks in windows using python

I haven't done any tkinter in quite a while, but there seems to be "FocusIn" and "FocusOut" events. You might be able to bind and track these to solve your issue.
