Re: Tkinter widgets into classes.

[Lewis Wood]

Thanks all who replied, will look further into megawidgets and the Toplevel() 
function. Is there a way to get a separate window to return something when 
closed?

Tkinter widgets into classes.

[Lewis Wood]

I was wandering if I could dynamically change my GUI and after a few searches 
on Google found the grid_remove() function. What I'm wandering now is if there 
is a way to group a lot of widgets up into one, and then use the one 
grid_remove function which will remove them all.

Is it possible to do this in a class like this?

class group1:
label1=Label(text=Upon clicking the button).grid(row=0,column=0)
label2=Label(text=The menu will dynamically change).grid(row=1,column=0)

group1.grid_remove()

Oh and another question, say I make another window in the program itself using 
this:

def secondwindow():
root2=Tk()
root2.mainloop()

Would it be possible for me to use some code which would return True if one of 
these windows is currently up, or return False if the window is not up?

 No need. Only one at a time can be running,  and you won't return
 
  from this function till it's done.
 
 
 
 To put it another way, you only want one mainloop in your code.

But I can click the button Multiple times and it will create multiple windows?

 Not using the function you showed.

It does, this is the whole code:

from tkinter import *

root=Tk()
root.title(Second Root Testing)



def secondwindow():
root2=Tk()
root2.mainloop()


button1=Button(root,text=Root2,command=secondwindow).grid(row=0,column=0)



root.mainloop()

[Lewis Wood]

I cannot say how grateful I am to find such a community willing to help 3 
Thanks to everyone posting, learned a lot of new stuff :) Never knew you could 
just bring a local var into a def block using global inside of the function. 
Again, thanks for taking your time to help out newbies to programming such as 
myself.

Also anyone know how to create an entry box for Tkinter where you can only 
enter in 2 digits?

Re: Tkinter GUI Error

[Lewis Wood]

When I try to use the labelent1.configure, it greets me with an error:
AttributeError: 'NoneType' object has no attribute 'configure'

I changed the labelent's to global. Don't suppose you know why?
Also how would I go about using an object for the entire window. I am still a 
Novice at Tkinter and Python but can make my way around it.
