tkinter grid having problems

Recommended Posts

Hey, I am currently having problems with the .grid() function in python. 

Can someone help?


import tkinter as tk
from tkinter import ttk

LARGE_FONT = ("Verdana", 12)

class funapp(tk.Tk):

    def __init__(self, *args, **kwargs):

        tk.Tk.__init__(self, *args, **kwargs)

        ## tk.Tk.iconbitmap(self, default="testicon.ico")

        container = tk.Frame(self)
        container.pack(side="top", fill="both", expand = True)
        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)
        

        self.frames = {} # creating a dictionary

        for F in (StartPage, Page1):

            frame = F(container, self)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky = "nsew")

        self.show_frame(StartPage)

    def show_frame(self, cont):

        frame = self.frames[cont]
        frame.tkraise()

def qf(param):
    print (param)

class StartPage(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        label = tk.Label(self, text="Home", font=LARGE_FONT)
        label.pack(pady=10, padx=10)

        button1 = ttk.Button(self, text = "Page 1",
                            command = lambda: controller.show_frame(Page1)) # can change to home page
        button1.pack()
        
        

class Page1(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)
        label = tk.Label(self, text="Page 1!!!", font=LARGE_FONT)
        label.pack(pady=10, padx=10)

        button1 = ttk.Button(self, text = "Back to Home",
                            command = lambda: controller.show_frame(StartPage))
        button1.grid(row = 0, column = 0)
        


app = funapp()
app.geometry("1280x720") # changes the size and shape of the entire
app.mainloop()

not sure if I should put this directly into the message or should have uploaded a file. I can change it to a txt file if there is a problem.
