 [Tkinter] how do i add a margin to a Listbox
#21
Well after finally getting a moment to look at the code and implementing it into my code... for some reason it does not work. It is clearly something I am doing wrong in the initial writing of the code.

Both of the code version works perfectly as they are but when it is put into my original coding it will not display the Listbox widget at al. No error codes are given but it is not seen.

Hi DT2000

So for me it is becoming difficult to understand what is going on at your side. Unfortunately without seeing your complete code piece i can't help you further on. Here i have tested the code successfully with Ubuntu 18.04, Windows 10 and Python 3.5.2

DT2000 - It seems as though you are taking the code that wuf wrote, and trying to manipulate it into some other body of code.
The code wuf debugged, is what you said was your complete code.
Therefore, delete what you presented to wuf, and replace it 100 % with wuf's debugged version.

I uploaded the window_2 part of the code, without the background image because that is where the Listbox is used.

Here is the full code.

window_2 starts at line 54. The Listbox code is at line 332.

Hi DT2000

Thanks for showing your extended app script. As i see you are using mainly the place layout structure. Thats the reason why you could not implement my recommended 'listbox' proposal. For me its also very difficult to integrate my recomondations in your existing script as it is. I would have to modify your whole script. Unfortunaly i have no time for this. Wishing you good luck for the further development of your application.

Being new to python I am still learning the best ways to write. I appreciate the time taken to look things over.
For now I will live with the lack of padding inside the Listbox, at least until I am more familiar with proper layout techniques so I can rewrite the code.

Thank you, to you and Larz for all the advice and help it is greatly appreciated.
