I'm trying to close the previous window when I click the button to go to the next window. I'm not being able to do it. What's wrong?
from tkinter import *
def newwindow2():

newwindow2.title('Nível da grama região 3')
newwindow2.geometry('580x520')
labl3 = Label(newwindow2, text='A foto do nível da grama na região 3 foi tirada: \n', font=30).place(x=110, y=10)

As you can see I'm trying to use .destroy() but it's not working. Any solutions? I'm just starting to learn Python so I'm aware this might be very simple. Thanks for the help!
I see see several problems. The main one being that you can't call newwindow.destroy() because newwindow is a function not a tk.Toplevel widget. Another is the janela1.destroy() destroying itself, and it's the root window.
Instead of destroying windows, you can just withdraw() them. Here's code that I think does what you want:
from tkinter import *
import tkinter as tk
def make_newwindow2():
# newwindow.destroy()
global newwindow2
newwindow.withdraw()
newwindow2 = tk.Toplevel()
newwindow2.title('Nível da grama região 3')
newwindow2.geometry('580x520')
labl3 = Label(newwindow2,
text='A foto do nível da grama na região 3 foi tirada:\n', font=30)
labl3.place(x=110, y=10)
tk.Button(newwindow2, text='Fim', command=root.quit).place(x=250, y=470)
def make_newwindow():
# janela1.destroy()
global newwindow
root.withdraw()
newwindow = tk.Toplevel()
newwindow.title('Nível da grama região 2')
newwindow.geometry('580x520')
labl2 = Label(newwindow,
text='A foto do nível da grama na região 2 foi tirada:\n', font=30)
labl2.place(x=110, y=10)
tk.Button(newwindow, text='Próximo', command=make_newwindow2).place(x=250, y=470)
root = tk.Tk()
root.title('Nível da grama região 1')
root.geometry("580x520")
labl1 = Label(root, text='A foto do nível da grama na região 1 foi tirada: ', font=30)
labl1.place(x=110, y=10)
tk.Button(root, text='Próximo', command=make_newwindow).place(x=250, y=470)
root.mainloop()
Something else I changed, even though it wasn't strictly necessary, was how you were assigning the result of calling place() to the names of a widgets. Since place() (and pack() and grid()) always return None, that's the value the variable will end up with — which is never what you'd want. You're getting away with it here, but only because those names aren't referenced again.

I'm having trouble creating buttons in tkinter, I've tried doing it in different ways, but I haven't reached the solution.
It turns out that one of the requirements that they have made me when making this calculator is to create three text boxes and eleven buttons, so when I create the positioning of the boxes and I want to place the buttons they do nothing, if I try to tell them to position in column 3, row 4 is not positioned.
Image of the code output
This is the code, if you see something wrong that I have not been able to see and that is the cause of such an error, I would appreciate it

Please help would be very good, thank you ...
I think you must first of all use only one type of geometry management, and then keep it simplest, I've made some changes to show how to use grid manager with some loop.

You souldn't mix .pack(), .grid(), and .place() in the same master window.
I generate frames according to the selection made on a treeview. this treeview is connected to a sqllite3 type database. I have a concern which is the following (I hope to be clear in my explanations). once the selections are made (example 3 selections), I delete one of them. Then I make a new selection. the added frame is positioned on the last current one. instead of getting 3 frames again, we only get two frames. While the Full_list has 3 selection (Full_List is a list containing the information of the selections made). I think the problem is with the var variable which I can't seem to resolve. in the code, this happens between the selectItem (frame) and removeLabel (frame, var) function. thanks for your time for a solution.

As you can see my program has a window in which I put a couple of Labels, and a couple of buttons. The problem is caused by the function asigned to the load_button (def function_load), because the filedialog opens but I suppose the process keeps running and that causes the button stay pressed.
You needn't to bind a event for your button widget if you want to do something when you press them,just set a command for it.And you have a spelling error in your code.Your final code:

I have a problem that i still cant solve, specifically involving tkinter.
Eventhough some parts of the code are written in spanish I hope its not a problem.

If you spot an error,Ill apreciate all feedback!
BTW when I run this code I get an error saying :
TypeError: a float is required
modulo = Vel_in_y* math.sin(Angulo_desp.get())
math.sin has no idea what to do with an IntVar ... you must get the value
the same applies everywhere else you are trying to access the value of the variables
I don't understand why you use IntVal instead int .
You need to convert IntVal type to int type by use the get function .
Here is your code , it was fixed :
def calcular_modulo(root):
modulo = Vel_in_y.get()* math.sin(Angulo_desp.get())
label = tkinter.Label(frame,textvariable=modulo)
label.pack()
if modulo == 0:
modulo = math.sqrt(Vel_in_x.get()**2+ Vel_in_y.get()**2)
label = tkinter.Label(frame,textvariable=modulo)
label.pack()

On this GUI, I have a button, and on this button, I do this:
def OnButtonClick(self):
#self.labelVariable.set( self.labelVariable.get() + "\n" + self.entryVariable.get()+" (You clicked the button)" ) #muda o texto da labelVariable com o valor de entryVariable
#self.texto.insert(Tkinter.END, self.entryVariable.get() + "\n")
from AcharCompatibilidadeEntreAmigosTudoJunto import AcharCompatibilidadeEntreAmigosTudoJunto
achaCompatibilidade = AcharCompatibilidadeEntreAmigosTudoJunto(self.access_token, self)
achaCompatibilidade.calcularCompatibilidadeEntreEsseAmigoETodosOsMeusAmigos(self.entryVariable.get())
self.entry.focus_set()#seleciona o texto todo assim que o usuário aperta botão ou enter
self.entry.selection_range(0, Tkinter.END)
The problem is that I want to change the cursor of my mouse to a loading cursor when the user clicks on the button and it will have to change back when the .onButtonClick() function ends. How do i do that?
Have the button pressed call a method which sets the cursor into whatever you want it to, and then in the same method start a new thread of the actual method you were trying to call. Then at the end of this method change the cursor back.
This link: http://effbot.org/zone/tkinter-busy.htm should help you with changing of the cursor, and a quick google search or search on this website should give you all the information you need for threading. The module you are looking for is called 'threading' by the way.
