Create map widget on Toplevel window

[akrish1998]

Hi,

I'm currently using tkintermapview version 1.19 and python 3 version 3.9.6 and I'm running the following code but I'm seeing a blank map:

import tkinter
import tkintermapview

# create tkinter window
root_tk = tkinter.Tk()
root_tk.geometry(f"{800}x{600}")
root_tk.title("map_view_example.py")

# create map widget
map_widget = tkintermapview.TkinterMapView(root_tk, width=800, height=600, corner_radius=0)
map_widget.place(relx=0.5, rely=0.5, anchor=tkinter.CENTER)

root_tk.mainloop()

Is there something I can do to see the map correctly?

Thanks

I don't know what's the problem there, for me everything is working fine on Windows. What you can do is search the following url in your browser and see if you receive a valid tile image or an error message:

the map is working when i call it outside a function.

from tkinter import*
import tkintermapview

self=Tk()
my_label=LabelFrame(self)
my_label.place(x=0,y=100)

map_widget=tkintermapview.TkinterMapView(my_label,width=1270, height=500, corner_radius=20)
map_widget.pack()
self.mainloop()

this works and successfully brings up the map

from tkinter import*
import tkintermapview
win=Tk()
def map_win():
    import tkintermapview
    winmap=Tk()
    winmap.title("Set Location")
    winmap.geometry("1366x768")

    my_label=LabelFrame(winmap)
    my_label.pack(pady=20)

    map_widget=tkintermapview.TkinterMapView(my_label,width=800,height=600)
    map_widget.pack()
    winmap.mainloop()
next_btn=Button(win,text="next",height=2,width=20, command=map_win)
next_btn.place(x=450,y=476)
win.mainloop()

The above code does not work and the resultant window which opens on the click of the button looks like this: and returns the following error:

"C:\Users\User\AppData\Local\Programs\Python\Python311\Lib\tkinter__init__.py", line 2832, in _create return self.tk.getint(self.tk.call( ^^^^^^^^^^^^^ _tkinter.TclError: image "pyimage3" doesn't exist

My use case requires me to open the map window using a button , whose command is to create a new window which contains the map. Is there anything i can do to fix it?

Thanks in advance!

I am also facing the same issue, the map isn't showing up properly and instead ,showing a blank space.

That's not how you create a secondary window in tkinter. This cannot work. There should only be one instance of Tk() and mainloop() can only be called once. You should create a toplevel object like this:

import tkinter
import tkintermapview

def map_win():
    toplevel_window = tkinter.Toplevel()
    toplevel_window.title("Set Location")
    toplevel_window.geometry("1366x768")

    my_label = tkinter.LabelFrame(toplevel_window)
    my_label.pack(pady=20)

    map_widget = tkintermapview.TkinterMapView(my_label, width=800, height=600)
    map_widget.pack()

app = tkinter.Tk()
app.geometry("800x600")

next_btn = tkinter.Button(app, text="next", height=2, width=20, command=map_win)
next_btn.place(x=450, y=476)

app.mainloop()

But that's also not how you would create such an app with a secondary window. Because with the method above you create a new window every time you press the button and that's not how it should be. With the following object oriented approach, you can create only one map window at a time and that's also the architecture of how I would do such an app:

import tkinter
import tkintermapview

class MapWindow(tkinter.Toplevel):
    def __init__(self):
        super().__init__()
        self.title("Set Location")
        self.geometry("1366x768")

        self.my_label = tkinter.LabelFrame(self)
        self.my_label.pack(pady=20)

        self.map_widget = tkintermapview.TkinterMapView(self.my_label, width=800, height=600)
        self.map_widget.pack()

class App(tkinter.Tk):
    def __init__(self):
        super().__init__()
        self.geometry("800x600")

        self.next_btn = tkinter.Button(self, text="next", height=2, width=20, command=self.open_map_window)
        self.next_btn.place(x=450, y=476)

        self.map_window = None

    def open_map_window(self):
        if self.map_window is None or not self.map_window.winfo_exists():
            self.map_window = MapWindow()  # create new window
        else:
            self.map_window.lift()  # bring already existing window to the top

app = App()
app.mainloop()
