Bonjour,
Je suis un débutant en python.
Quand je lance le code la fenetre Tkinter se lance bien mais quand j'essaie d'interagire il ne se passe rien je pense que c'est dus car mon code est en dehors du
root = tk.Tk()
est du
root.mainloop()
Mais quand je met mon code python a l'interieur il me dit : FileNotFoundError: [WinError 3] Le chemin d’accès spécifié est introuvable: ''
car pour avoir ce chemin d'accès il faut remplir un champ de texte dans ma page tkinter et appuyer sur un bouton pour exécuter la fonction prévue a cet effet. Mais comme le code est a l'interieur de la boucle de la fenètre tkinter je n'ai pas le temps de remplire le champ de texte.
Peut-être faut t'il crée une autre fonction je sait pas je suis au pied du mur.
Pouvez vous m'aider s'il vous plait.
J'ai essayé de changer l'ordre de mes bloc de code mais pas d'effet.
i am trying to learn python from a book. I'm trying to do an exercise with tinker. Click on a button and advance to the limit of the window. Then always by clicking on the same button to advance the circle to the other side of the window. Thanks for your help.
from tkinter import *
def avance(n, g):
global x, y, step
# nouvelles coordonnées :
x[n] = x[n] + g # deplacement de l'axe des x
# déplacement du dessin dans le canevas :
can.coords(bille[n], x[n]-10, y[n]-10, x[n]+10, y[n]+10)
# affichage pour info du x:

i = 0
if x[n] >= 50:
while i <= 400:
step = +20
i = i+5
if x[n] >= 400:
step = -20
i = i-5
return step
def go():
avance(0, step)
bille = [0] # liste servant à mémoriser les références du cercle
x = [50] # X de départ
y = [100] # y de départ
step = 0 # "pas" de déplacement initial
# Construction de la fenêtre :

fen.title("avance quand on clique jusqu'à la limite de la fenêtre et revient")
Info = Label(fen) # pour afficher l'info du x
Info.grid(row=3, column=0)
# Canvas :

can.grid(row=2, column=0, columnspan=2)
bille[0] = can.create_oval(x[0]-10, y[0]-10, x[0]+10, y[0]+10,

# bouton avance :
f = Frame(fen)
f.grid(row=4, column=0, sticky=W, padx=10)
Button(f, text="Go", fg='blue', command=go).pack(side=LEFT)
fen.mainloop()
the problem is that when the ball reaches the limit (first while loop) when it starts the second loop, it returns to the conditions of the first.
sorry for my English
thank for help

I use this method for Game of Life but I would like to automatize the steps. I tried to change the next_step but it doesn't work.
Could you help me please?
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.

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.
