Focusing on next entry box after typing a number in current entry box

Question

I'm trying to see if there's a way to type a number between 1 and 4 into an entry box, then go to the next entry box (with the number entered into the box; the code below skips to the next entry without entering anything)

I'm creating a program that will take item-level data entry to be computed into different subscales. I have that part working in different code, but would prefer not to have to hit tab in between each text entry box since there will be a lot of them.

Basic code:

from tkinter import *

master = Tk()
root_menu = Menu(master)
master.config(menu = root_menu)

def nextentrybox(event):
    event.widget.tk_focusNext().focus()
    return('break')

Label(master, text='Q1',font=("Arial",8)).grid(row=0,column=0,sticky=E)
Q1=Entry(master, textvariable=StringVar)
Q1.grid(row=0,column=1)
Q1.bind('1',nextentrybox)
Q1.bind('2',nextentrybox)
Q1.bind('3',nextentrybox)
Q1.bind('4',nextentrybox)
Label(master, text='Q2',font=("Arial",8)).grid(row=1,column=0,sticky=E)
Q2=Entry(master, textvariable=StringVar)
Q2.grid(row=1,column=1)
Q2.bind('1',nextentrybox)
Q2.bind('2',nextentrybox)
Q2.bind('3',nextentrybox)
Q2.bind('4',nextentrybox)
### etc for rest of questions

### Scale sums, t-score lookups, and report generator to go here

file_menu = Menu(root_menu)
root_menu.add_cascade(label = "File", menu = file_menu)
file_menu.add_separator()
file_menu.add_command(label = "Quit", command = master.destroy)

mainloop()

Thanks for any help or pointers!

It's because you've bound those number keys solely to move fields. What you need to do instead is remove that condition so that you can enter those numbers, and instead add a condition that checks if one of those numbers has been input before moving on. Edit: For clarity, try writing in any LETTER, or number >4, or 0. — visualnotsobasic, Feb 05 '19 at 16:00

The simplest solution is to enter the event keysym before proceeding to the next field.

In the following example, notice how I added a call to event.widget.insert before moving the focus:

def nextentrybox(event):
    event.widget.insert("end", event.keysym)
    event.widget.tk_focusNext().focus()
    return('break')
