Functions with Parameters with Tkinter GUI buttons - Tkinter tutorial Python 3.4 p. 3

In this Tkinter with Python 3 tutorial video, we cover how to not only pass functions as commands for our buttons, but also pass parameters through those functions using lambda.

[Kazutadashi]

Hopefully this class stuff will start to make more sense as I go through the GUI tutorials, but so far you have had some of the best tutorials on youtube! Keep it up man!

I am seriously envious of your typing skills! 😎

[lukasz]

this is exactly what I needed! lambda is the king, thank you ;)

Great concise information explaining a lot of the convention in an easily understandable way.  Great work, thank you much.

Excellent! Answered a question I had on callbacks with parameters 😀. Thanks!

I want to pass multiple variables through the quick function that lambda creates, what should I do?

[mittromney]

Just wondering how I can pass variables/parameters between classes or, if that topic is in one of the videos further down the line, which video it appears in? Thanks!

form a class i have to check some values in Login then if it returns true then i want to move to another frame but i cannot use the variables here is the snippet of the code

class Login(tk.Frame):
def __init__(self, parant, controller):

tk.Frame.__init__(self, parant)
self.un= tk.Entry(self, textvariable=StringVar())
self.un.grid(row=3, column=2)
self.pw = tk.Entry(self, textvariable=StringVar())
self.pw.grid(row=4, column=2)

self.butsavedata = ttk.Button(self, text='Login', width=10, command=lambda:controller.show_frame(login))
self.butsavedata.grid(row=7, column=0)

class login(tk.Frame):
def __init__(self, parant, controller):
tk.Frame.__init__(self, parant)
loglist=[self.un.get(), self.pw.get()]
x=Auth.main(loglist)
if x:
self.butsavedata.destroy()
self.butquit = ttk.Button(self, text='Continue', width=10, command=lambda:controller.show_frame(hotel))

is it possible to design a code to get a new frame by clicking on the button("visit page 1") which will get the values of the same page .
for eg. a restaurant program after giving a total a button is provided in a frame as bill, and on clicking it you will get the exact bill that is printed on the previous frame .and the new frame includes bill paid message, , , , ..., , ., .., , . so basically i want to know hot to get same arguments on a new frame.

Great tutorial! thanks a lot. How can i change the size of each window? how can i add a menu bar tu first page?

[akshatsharma]

why did we take container ? does it means that container is a frame and all other pages are loaded as frames in this container frame.?

[kaden]

Can anyone please tell me which video he goes into threading with this Tkinter application?

[underwaterguitar]

Thanks, your videos are very helpful. Someone showed me the "partial" function you can use by importing "partial" from "functools":
from functools import partial
then in your mainloop:
button1 = Button(topFrame, text="---", command=partial(---, ---))
maybe you will cover this in a later video, but is "lamda" doing the same thing as "partial"?

Do you have a video were you make. Box and the player can't walk into it or it activates something
