Check if Entry widget is selected

I'm making a program on the Raspberry Pi with a touchscreen display. I'm using Python Tkinter that has two entry widgets and one on screen keypad. I want to use the same keypad for entering data on both entry widgets.

Can anyone tell me how can i check if an entry is selected? Similar like clicking on the Entry using the mouse and the cursor appears. How can I know that in Python Tkinter?

Thank you.

There is always a widget with the keyboard focus. You can query that with the focus_get method of the root window. It will return whatever widget has keyboard focus. That is the window that should receive input from your keypad.

You can use events and bindigs to catch FocusIn events for your entries.

entry1 = Entry(root)
entry2 = Entry(root)

def callback_entry1_focus(event):
    print 'entry1 focus in'

def callback_entry2_focus(event):
    print 'entry2 focus in'

entry1.bind("<FocusIn>", callback_entry1_focus)
entry2.bind("<FocusIn>", callback_entry2_focus)
