Depending on exactly what you want to do, it may be possible in
Tkinter. You can use something like this to find out when a widget
gets and loses focus:
import Tkinter
def gotFocus(event):
print 'Focus in'
def lostFocus(event):
print 'Focus out'
root = Tkinter.Tk()
e = Tkinter.Entry()
e.bind('<FocusIn>', gotFocus)
e.bind('<FocusOut>', lostFocus)
e.pack()
root.mainloop()
Also, you can use this to set the focus to a widget.
e.focus_set()
