Tkinter create RadioButtons from dictionary issue - dictionary

Question

Here is my problem: I've made a tkinter program which calculate the cost of a creation my wife make. She sews accessories. So far my program is working pretty well. I search in a JSON file if this fabric already exist in some kind of catalogue.
When my catalogue have the same fabric name, I want to make a popup window with radiobutton. By checking the correct radiobutton I chose the correct fabric. So I've extracted the dictionary of same fabric names, when I type the fabric name entry and then click on enter, it sends the dictionnary to the popup window which creates radiobutton in a for loop.
The problem comes here, my radiobutton are correctly made but impossible to get there state nor which button is checked...
First, here's the dictionary :
{"Tissu 1": {"Type": "Tissu", "Matière": "coton", "Prix du coupon": "8",
"Laise du coupon (cm)": "150",
"Prix au mètre (€)": 8.0,
"Fournisseur": "lol"},
"Tissu 2": {"Type": "Tissu", "Matière": "molleton", "Prix du coupon": "10",
"Laise du coupon (cm)": "150",
"Prix au mètre (€)": 10.0,
"Fournisseur": "lol"},
"Tissu 3": {"Type": "Tissu", "Matière": "coton", "Prix du coupon": "12",
"Laise du coupon (cm)": "150",
"Prix au mètre (€)": 12.0,
"Fournisseur": "mol"}}
Here's my code:
First there is the main class:
class ProgramCalcul(tk.Tk):
def __init__(self, *args, **kwargs):
self.frames = {}
for F in (StartPage, CalculTissuPage, CalculMercPage):
frame = F(container, self)
self.frames[F] = frame
frame.grid(row = 0, column = 0, sticky = "nsew")
self.show_frameSP(StartPage)
def show_frameSP(self, cont):
frame = self.frames[cont]
frame.tkraise()
Then I have a class for each other calcul page
Here is the fabric calcul page (I've removed some entries and other widgets for legibility and because they work fine):
class CalculTissuPage(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
tissuType = tk.StringVar()
TissuNameEntry = tk.Entry(self, textvariable = tissuType, width = 50)
TissuNameEntry.grid(row = 2, padx = 20, pady = 5, sticky = "ew")
def keyPress(arg):
checkCatalogueTissu(TissuNameEntry.get())
TissuNameEntry.bind('<Return>', keyPress)
def checkCatalogueTissu(txt):
tmpDict = {}
with open("catalogue tissu.json") as json_file:
data = json.load(json_file)
dictLen = len(data)
for i in range(1, dictLen+1):
if "Tissu {}".format(i) not in data:
pass
else:
if data["Tissu {}".format(i)]["Matière"] == txt:
tmpDict["Tissu {}".format(i)] = data["Tissu {}".format(i)]
popupRadio(tmpDict)
def setText(txtPrix, txtFournisseur, txtLaise, txtLong):
couponPrixEntry.delete(0,tk.END)
couponPrixEntry.insert(0,txtPrix)
fournisseurEntry.delete(0, tk.END)
fournisseurEntry.insert(0, txtFournisseur)
laiseDimEntry.delete(0, tk.END)
laiseDimEntry.insert(0, txtLaise)
longCouponEntry.delete(0,tk.END)
longCouponEntry.insert(0,txtLong)
And finally the function which create the popup in which appear the radiobuttons:
def popupRadio(tmpDict):
popup = tk.Toplevel()
popup.wm_title("!")
popupVar = tk.IntVar()
def checkState(popupVar):
print(popupVar.get())
for (key, val) in tmpDict.items():
tk.Radiobutton(popup, text = key, variable = popupVar, value = val, command = checkState(popupVar)).grid()
print(key, popupVar.get())
chk = ttk.Button(popup, text = "Select this", command = checkState(popupVar))
chk.grid()
popup.mainloop()
When I run it, the checkState() method seems to run automatically and then the chk button doesn't do anything... I can check the radiobuttons but nothing happens (even if I pass the command=chechState in the radiobutton settings. I want to get which button is checked to use this value in my setText() method further.
for the moment, here is the output the print() send in my console :
0
Tissu 1 0
0
Tissu 3 0
0
So here I am, it's been 2 days since I've tried evrything I found on the web but nothing...
A little help would be very appreciated
PS: sorry if my english is not perfect :)
