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
from tkinter import *
#instancia de calculadora
calculadora = Tk()
#Nombre de la ventana grafica
calculadora.title("Practica calculadora con tkinter")
#tamano de la ventana
calculadora.geometry("600x750")
#color personalizado de la ventana
calculadora.configure(bg="black")
firtDisplay = Entry(calculadora, state="readonly", width=25).place(x=0, y=5)
secondDisplay = Entry(calculadora, state="readonly", width=25).place(x=300, y=5)
thirdDisplay = Entry(calculadora, state="readonly", width=25).place(x=149, y=40)
#Botones
Button(calculadora, text="7", width=15).grid(row=5, column=3)
Button(calculadora, text="8", width=15)
Button(calculadora, text="9", width=15)
calculadora.mainloop()
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 tried to make a simple code to do a joke with my friends. It's based in: they entry with her names, and when they clicked in button, a answer appears. Before this, i maked a simple code based in: if(xxxx), so print(xxxxx). Now, i using tkinter to give a GUI to my code. But, i don't know how make the button do this when i push him.

Who can help a poor beginner?
You should have done a little research before asking. Learn about how-to-ask. And Refer here to know about the Entry widget in Tkinter.
Declare a string variable (needed to store the user's input.) Then, make that string variable as the Entry box's textvariable. And, set "command=piadinhas" so that the function is called on clicking that button.
inp = StringVar()
entrada_nome = Entry(janela,textvariable = inp)
...
botao_resultado = Button(janela, width=20, height=2, command=piadinhas)
Also, make these changes in your function:
def piadinhas():
nome = inp.get()
Read the documentation to know more.
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.

So I got the assignment to make a small Bingo App (Windows btw) after I followed a few webinars on Tkinter GUI and some Googling.
I have made successfull little apps that worked correctly, but this time I try to make it with knowledge I think I have.
Anyway, in that Bingo app, I want 50 labels that represent 50 numbers of the Bingo card, 5 rows of 10 numbers.
I know how to align them, but they need to show up first.
Can you look at my code and assess what I do wrong?
Ignore the many Dutch comments :)

You need to learn about data structures, like list.
You had root.mainloop() early on in the code. That starts a loop. Nothing after that is executed until the window is closed, which means it has to be at the end.
Choose one geometry manager. You can't use both grid() and pack() in the same parent widget, much less on the same child widget.
You had some typos, like label7 = instead of label17 =, and label28.Label instead of label28 = Label. Most of these would never have happened if you had used a list.
Obviously, 50 labels won't fit in a single column in a window of that size. You've got some decisions ahead of you involving window size, label placement, possible scrollbar, and so on.
The resulting code taking into account all these points (except the last) is shown below.
from tkinter import *
root = Tk()
root.wm_title("Bingo Python")
root.wm_maxsize("800","600")
root.wm_minsize("800","600")
labels = [Label(root, text=i) for i in range(1, 51)]
for label in labels:
label.pack()
root.mainloop()
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.
When trying to calculate the hypotenuse of a triangle with Vel_in_y as the opposing side.
import tkinter
import math
window= tkinter.Tk()
frame = tkinter.Frame(window)
frame.pack()
Velocidad_in =tkinter.IntVar()
Angulo_desp = tkinter.IntVar()
Altura_max = tkinter.IntVar()
Alcan = tkinter.IntVar()
Temp = tkinter.IntVar()
Vel_in_y= tkinter.IntVar()
Vel_in_x= tkinter.IntVar()
var = [Velocidad_in,Angulo_desp ,Altura_max,Alcan,Temp,Vel_in_y,Vel_in_x]
opciones_de_Vel = ['Velocidad Inicial en X','Velocidad Inicial en Y','Modulo de Velocidad']
def Velocidad_Inicial(root):
for (tipo,var) in ((' La Velocidad Inicial en X',Vel_in_x),(' La Velocidad Inicial en Y',Vel_in_y),(' El Modulo de Velocidad',Velocidad_in)):
label = tkinter.Label(frame,text= 'Inserte '+ tipo)
label.pack()
entry= tkinter.Entry(frame,textvariable = var)
entry.pack()
def Angulo_Despegue(root):
label = tkinter.Label(frame,text='Inserte el Angulo de despegue')
label.pack()
entry= tkinter.Entry(frame,textvariable = Angulo_desp)
entry.pack()
def Altura_Maxima(root):
label = tkinter.Label(frame,text='Inserte la Altura Maxima')
label.pack()
entry= tkinter.Entry(frame,textvariable = Altura_max)
entry.pack()
def Alcance(root):
label = tkinter.Label(frame,text='Inserte el Alcance')
label.pack()
entry= tkinter.Entry(frame,textvariable = Alcan)
entry.pack()
def Tiempo(root):
label = tkinter.Label(frame,text='Inserte el Tiempo')
label.pack()
entry= tkinter.Entry(frame,textvariable = Temp)
entry.pack()
def calcular_modulo(root):
modulo = Vel_in_y* math.sin(Angulo_desp)
label = tkinter.Label(frame,textvariable=modulo)
label.pack()
if modulo == 0:
modulo = math.sqrt(Vel_in_x**2+ Vel_in_y**2)
label = tkinter.Label(frame,textvariable=modulo)
label.pack()
button = tkinter.Button(frame,text='respuesta' ,command = lambda: calcular_modulo(window))
button.pack()
menubar = tkinter.Menu(window)
option_menu =tkinter.Menu(menubar)
option_menu.add_command(label= 'Velocidad Inicial',command=lambda:Velocidad_Inicial(window))
option_menu.add_command(label= 'Angulo de Despegue',command=lambda:Angulo_Despegue(window))
option_menu.add_command(label= 'Altura Maxima',command=lambda:Altura_Maxima(window))
option_menu.add_command(label= 'Alcance',command=lambda:Alcance(window))
option_menu.add_command(label= 'Tiempo', command=lambda:Tiempo(window))
menubar.add_cascade(label= 'Tipo de Variable',menu=option_menu)
window.config(menu=menubar)
window.mainloop()
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()
I am using Tkinter to create my UI on python.
Currently, the .__init__() and .initialize() are like this:
def __init__(self,parent):
Tkinter.Tk.__init__(self,parent)
self.parent = parent
self.initialize()
def initialize(self):
self.grid()
self.entryVariable = Tkinter.StringVar()
self.entry = Tkinter.Entry(self,textvariable=self.entryVariable)#Entry é um nome de Textfield da tela
self.entry.grid(column=0,row=0,sticky='EW')#EW é pra ele grudar nas edges
self.entry.bind("<Return>", self.OnPressEnter)#dispara onPressEnter quando enter é pressionado no ttext field
self.entryVariable.set(u"Entre com o nome do amigo que você quer convidar pra sair")
button = Tkinter.Button(self,text=u"Ver compatibilidade!",
command=self.OnButtonClick)#botao clicavel dispara onButtonClick
button.grid(column=1,row=0)
self.labelVariable = Tkinter.StringVar()
#label = Tkinter.Label(self,textvariable=self.labelVariable, # label que usa variável labelVariable como texto
#anchor="w",fg="white",bg="black", height=35, width=55)#NOVO WIDTH E HEIGHT FIXO
#PESQUISAR COMO SE ADD SCROLLBAR PRA LABEL, SE TEM COMO OU ADD LABEL EM WINDOW E AIH BOTAR SCROLLBAR
self.texto = Tkinter.Text(self, fg="white",bg="black", height=35, width=55)
self.texto.grid(column=0,row=1,columnspan=2,sticky='EW')
# create a Scrollbar and associate it with txt
scrollb = Tkinter.Scrollbar(self, command=self.texto.yview)
scrollb.grid(row=1, column=1, sticky='nsew')
self.texto['yscrollcommand'] = scrollb.set
#label.grid(column=0,row=1,columnspan=2,sticky='EW')
self.labelVariable.set(u"Hello !")
self.grid_columnconfigure(0,weight=1)#estica a coluna 1 mesmo com resize da janela
self.resizable(True,True)#soh ppode resize horizontalmente! vertical nao pode
self.update()
self.geometry(self.geometry())
self.entry.focus_set()#textfield foca
self.entry.selection_range(0, Tkinter.END)
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.
