ny help to get the proper syntax regarding zoom. (great confusion in tha family).
Anyone? lblzoomlvl = customtkinter.CTkLabel(window, width=80, font=("Ariel",16,"bold"),text_color="#0000ff", fg_color="#ffffff", text="")
lblzoomlvl.place(x=1160,y=241)
def cmdinczoom(event):
#read Text from label lblzoomlvl into an integer variable zoom
temp = lblzoomlvl["text"]
zoom =int(temp)
if (zoom<16):
# add 1 to int variable zoom
zoom=zoom+1
# update text on label lblzoomlvl
lblzoomlvl.configure(text=zoom)
# set mouse x,y position
mouse.position = (32,53)
# click once with left mouse button
mouse.click(Button.left,1)
# update text on lblzzoom by zoom
lblzoomlvl.configure(text=zoom)
btninczoom = customtkinter.CTkButton(window, width=20, height=10, font=("Ariel",20,"bold"), border_color="#add19e", fg_color="#aaaaaa",text_color="#000000", text="+",command=cmdinczoom)
lblzoomlvl.[output]Tk.bind("<Up>",cmdinczoom)
File "D:\Python311\Lib\tkinter\__init__.py", line 1448, in bind
return self._bind(('bind', self._w), sequence, func, add)
^^^^^^^^^^
AttributeError: 'str' object has no attribute '_bind'. Did you mean: 'find'?

Try somewidget.bind("<Up>",cmdinczoom) perhaps.

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

I did consentrate on the arrow up and this solved it:
def pilopp(event):
tekst = lblzoomlvl.cget("text")
print(tekst)
if (int(tekst)<16):
# set mouse x,y position
mouse.position = (32,53)
mouse.click(Button.left,1)
tekst = int(tekst) + 1
lblzoomlvl.configure(text=tekst)
window.bind("<Up>",pilopp)

Why are you setting the mouse position and calling mouse click? Is that supposed to press the zoom button? zoom and set_zoom() are part of the map api, why not use them? You've posted code that uses the set_zoom() function.
Below is something I posted before with the addition of binding the arrow keys to zoom in and out.
import tkinter as tk
from tkintermapview import TkinterMapView
class MyWindow(tk.Tk):
"""A window that selects one of several pages to display."""
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.map = TkinterMapView(self, width=800, height=600, corner_radius=0)
self.map.pack(expand=True, fill=tk.BOTH)
self.map.set_position(60.03345, 11.35806) # Norway
self.map.set_address("fjellvegen 4, auli, norway", marker=True)
self.map.set_zoom(16)
self.zoom_label = tk.Label(self, text="Zoom = 16", font=(None, 24), width=20)
self.zoom_label.pack(padx=10, pady=10)
for key in ("<Left>", "<Right>", "<Up>", "<Down>"):
self.bind(key, self.zoom)
def zoom(self, event):
increment = {"Up": 1, "Right": 1, "Down": -1, "Left": -1}.get(event.keysym, 0)
value = max(1, min(19, self.map.zoom + increment))
self.zoom_label["text"] = f"Zoom = {value}"
self.map.set_zoom(value)

The best way to "keep track" of the zoom level is ask the map what the current zoom level is. There are too many ways this can change. You can change the zoom programmatically. You can change the zoom by hitting the zoom in (+) and out (-) buttons. You can zoom using the mouse wheel. There might be a way to have the map tell you when the zoom level changes. I didn't see it, but that doesn't mean it isn't there. If you want to display the current zoom level you could fire off an event that runs periodically to update the zoom display (use tkinter.after()). If you just want to know what the current zoom is, to save in a configuration file for example, just ask the map.zoom.

I wasnt aware of the api, just looked for a function which could possibly inc/dec zoom of the map. So I use the maps own zoom buttons instead. Thats not a good solution. Else I cut out the -/+ buttons and use keyboard down/up instead and plan to block the third mousewheel info as its dependant of mouse config. Do You mind post link to api?

value = max(1, min(19, self.map.zoom + increment))
self.zoom_label["text"] = f"Zoom = {value}"
self.map.set_zoom(value)
Your code is most elegant :)

Buttons already cuttoff. Mousewheel 3 will too, if possible. Just need the zoom for later rewinding of maparea and its marks/icons/symbols.

This does save and restore.

self.map.set_address("fjellvegen 4, auli, norway", marker=True)
self.map.set_zoom(16)
self.save()
# Create save and restore buttons for saving/restoring map position and zoom.
frame = tk.Frame(self)
frame.pack(expand=True, fill=tk.X)
button = tk.Button(frame, text="Save", command=self.save, font=(None, 24))
button.pack(side=tk.LEFT, expand=True, fill=tk.X)
button = tk.Button(frame, text="Restore", command=self.restore, font=(None, 24))
button.pack(side=tk.LEFT, expand=True, fill=tk.X)
# Bind arrow keys to zooming in/out.
self.zoom_keys = {"Up": 1, "Right": 1, "Down": -1, "Left": -1}
for key in self.zoom_keys:
self.bind(f"<{key}>", self.arrow_zoom)
def arrow_zoom(self, event):
"""Zoom map using arrow keys."""
increment = self.zoom_keys.get(event.keysym, 0)
self.map.set_zoom(self.map.zoom + increment)

self.saved_info = (self.map.zoom, self.map.get_position())
