Need assistance with determining which button was pressed

I'm using the complex_example.py included in the customkinter download. The code runs fine, but I just can't figure out how to tell what button was pushed self.sidebar_button_1, self.sidebar_button_2 or self.sidebar_button_3 as they all return the same message "sidebar_button click".

I'll admit that I know way more about COBOL and CICS then I do PYTHON, and I'm still trying to learn.

Any and all help will be greatly appreciated.

I tried adding adding additional parameters to the default values, which didn't work and also tried to print out the button name (text="name") in the def sidebar_button_event(self): print(text) but that didn't work either. I was hoping that it would give me a clue to the button pressed, but it just printed out ".".

I do not know why you needed to hang one handler on two buttons. But you can create your own handler for each button and call the desired method from them

self.sidebar_button_1 = customtkinter.CTkButton(self.sidebar_frame, 
command=self.sidebar_button_event_1)
self.sidebar_button_2 = customtkinter.CTkButton(self.sidebar_frame, 
command=self.sidebar_button_event_2)
...
def sidebar_button_event(self, *args, **kwargs):
print("sidebar_button click")
print(args, kwargs)
def sidebar_button_event_1(self):
self.sidebar_button_event("btn 1")
def sidebar_button_event_2(self):
self.sidebar_button_event("btn 2")

If you want you can edit your sidebar_button_event function ever so slightly to include another argument, such as the button number, and simply pass that argument through a lambda function when the button is clicked. It would look like this:

First redefine the sidebar_button_event:

def sidebar_button_event(self, buttonNum):
print(f"sidebar_button {buttonNum} click") # don't miss the f (formatted string)

And then edit your buttons as such:

self.sidebar_button_1 = customtkinter.CTkButton(self.sidebar_frame, command=lambda: self.sidebar_button_event(1))
self.sidebar_button_2 = customtkinter.CTkButton(self.sidebar_frame, command=lambda: self.sidebar_button_event(2))

I left the third button out both because it is disabled when you launch the program and to give you some practice if you want to enable it, but this will print to the console what button you are clicking! Enjoy Python!
