Resize window does not resize content in tkinter

Question

I am making my first GUI application and I ran into a dumb problem. Resizing the main window does not resize its contents and leaves a blank space. I read TKDocs and they only say that you should use sticky weight and column / row attributes, but I really don't understand how they work. Here is my code (only parts of the coverage of widgets, if you think that the problem is not here, I will lay out the rest):

from tkinter import * from tkinter import ttk root = Tk() mainframe = ttk.Frame(root, padding="3 3 12 12") mainframe.grid(column=0, row=0, sticky=(N, W, E, S)) mainframe.columnconfigure(0, weight=1) mainframe.rowconfigure(0, weight=1) player1 = StringVar() player2 = StringVar() player1.set('Player 1') player2.set('Player 1') timer=StringVar() running=BooleanVar() running.set(0) settimer = ttk.Entry(mainframe, width=7, textvariable=timer) settimer.grid(column=2, row=1, sticky=(N, S)) ttk.Button(mainframe, text="Start", command=start).grid(column=2, row=2, sticky=(N, S)) ttk.Label(mainframe, textvariable=player1, font=TimeFont).grid(column=1, row=3, sticky=(W, S)) ttk.Label(mainframe, textvariable=player2, font=TimeFont).grid(column=3, row=3, sticky=(E, S)) for child in mainframe.winfo_children(): child.grid_configure(padx=80, pady=10) root.mainloop() 

Thank you for your time!

Perhaps this will help you in the right direction. Be sure to adjust the column / row values ​​at each level.

 import tkinter.ttk from tkinter.constants import * class Application(tkinter.ttk.Frame): @classmethod def main(cls): tkinter.NoDefaultRoot() root = tkinter.Tk() app = cls(root) app.grid(sticky=NSEW) root.grid_columnconfigure(0, weight=1) root.grid_rowconfigure(0, weight=1) root.resizable(True, False) root.mainloop() def __init__(self, root): super().__init__(root) self.create_variables() self.create_widgets() self.grid_widgets() self.grid_columnconfigure(0, weight=1) def create_variables(self): self.player1 = tkinter.StringVar(self, 'Player 1') self.player2 = tkinter.StringVar(self, 'Player 2') self.timer = tkinter.StringVar(self) self.running = tkinter.BooleanVar(self) def create_widgets(self): self.set_timer = tkinter.ttk.Entry(self, textvariable=self.timer) self.start = tkinter.ttk.Button(self, text='Start', command=self.start) self.display1 = tkinter.ttk.Label(self, textvariable=self.player1) self.display2 = tkinter.ttk.Label(self, textvariable=self.player2) def grid_widgets(self): options = dict(sticky=NSEW, padx=3, pady=4) self.set_timer.grid(column=0, row=0, **options) self.start.grid(column=0, row=1, **options) self.display1.grid(column=0, row=2, **options) self.display2.grid(column=0, row=3, **options) def start(self): timer = self.timer.get() self.player1.set(timer) self.player2.set(timer) if __name__ == '__main__': Application.main()
