String int confused

[janeik]

There is a better way to associate label text with an int. Use a tk.variable.

import tkinter as tk


def cmdinczoom(event):
    print(event)
    increment = {"Up": 1, "Right": 1, "Down": -1, "Left": -1}.get(event.keysym, 0)
    zoom.set(max(1, min(zoom.get() + increment, 16)))


window = tk.Tk()
zoom = tk.IntVar(window, 1)
label = tk.Label(window, width=10, font=("Ariel", 16, "bold"), textvariable=zoom)
label.pack(padx=20, pady=20)
for key in ("<Left>", "<Right>", "<Up>", "<Down>"):
    window.bind(key, cmdinczoom)

window.mainloop()

Why does your key press callback function press a mouse button?

hello. I am using [url=https://github.com/TomSchimansky/TkinterMapView#create-polygon-from-position-
list]https://github.com/TomSchimansky/TkinterMapView#create-polygon-from-position-list[/url]



I wanted to keep track of zoom level on his app, view lvl on a label and use up and down arrow on keyboard to increase/decrease zoom level 1-16.

I didnt find any direct function in Schimansky app, so I thought I should do it programmatically
