[Tkinter] How to add an argument to a buttons command call

[petterg]

Hi!

using Python 3.6 and Tkinter

Im calling a method with a button. The method will change text on a label

Here is my button:

1	self.button5 = Button(middleframe6, text="Configure machine", command=self.ReceiptFormat, relief=RAISED)

which calls the method:

1 2	def ReceiptFormat(self, *args):     self.labelwindow['text'] = "Please select receipt Logo"

The label will get the new text

1 2	self.labelwindow = Label(master)         self.labelwindow.place(relx=0.45, rely=0.4, relwidth=0.47, relheight=0.47)

This works fine, but the problem is when im passing in an argument from the command. So im doing this:

1	self.button5 = Button(middleframe6, text="Configure RVM", command=self.ReceiptFormat("text"), relief=RAISED

The methode im calling

1 2 3

def ReceiptFormat(self, confirm, *args):         newtext = confirm         self.labelwindow['text'] = newtext

When im calling the method with the argument i get the following error message "AttributeError: 'SendT70' object has no attribute 'labelwindow'"

Any idead why i cant change the label text when im using arguments when calling the method?

To add arguments to a function called as a command you can use partial from functools

1 2 3 4

from functools import partial         self.button5 = Button(middleframe6, text="Configure RVM", command=partial(self.ReceiptFormat, "text"), relief=RAISED
