Tkinter padx problem

brad.bylls — Sat, 15 Aug 2020 19:29:12 GMT

I am building a Python tkinter GUI

The code below works just fine.

ttk.Label(win, text='Select a screw size from the list:',

anchor = 'e',

background = bgColor,

font = 16,

width = 25).grid(column=0, row=0)

But if I add the padx option,

ttk.Label(win, text='Select a screw size from the list:',

anchor = 'e',

background = bgColor,

padx = 5,

font = 16,

width = 25).grid(column=0, row=0)

I get an error:

Exception has occurred: TclError

unknown option "-padx"

Everything I find online says this should work.

Any ideas please?

Thank you.

Did not find a Python resource, but some Googling turned up info on ttk.Label and tkinter.Label having different options. So, maybe "padding"?

Compare these:

Are you using Windows or Mac? There are known issues with Tkinter on Mac, (https://www.python.org/download/mac/tcltk/). Because of that not much effort has gone into testing Tkinter with Fusion. I know in the early days of the API, I wrote some test apps thinking Tkinter would be a good GUI solution. I wrote them on Windows but then they didn't work on Mac and eventually abandoned the idea of using Tkinter as a general GUI solution.

You said in the early days you tried tkinter.
Have you tried it recently?
It seems so easy to work with compared to the API
And there is no good documentation and examples to help build a GUI in the
API.

Thank you for the input.
