I'm testing customtkinter module, and I have a problem. I've made test gui and some code, which should execute when button is clicked. Unfortunately when I click button I have error:
C:\Users\Jacek\Desktop>python test.py
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Python\Python38-32\lib\tkinter\__init__.py", line 1883, in __call__
return self.func(*args)
File "C:\Python\Python38-32\lib\site-packages\customtkinter\widgets\ctk_button.py", line 390, in clicked
self.function()
TypeError: 'str' object is not callable
That is not even in my code (I have only 250 lines). I've checked all types, and it's all good. Does anyone know how do deal with it?

CodePudding user response：
It says line 1883 because it the library line 1883 it giving a error because something is not correct in your script If I could see your code I could help solve this problem
CodePudding user response：
The error happens at this line
button = customtkinter.CTkButton(master=frame_left, text="Enter", command="print_test").grid(row=11, column=0, padx=20, pady=15)
you cannot call a function as a string to fix it try this line
button = customtkinter.CTkButton(master=frame_left, text="Enter", command=print_test()).grid(row=11, column=0, padx=20, pady=15)
