Troubleshooting

These items may solve your problem. Please check those you've done by changing - [ ] to - [X]

  • Searched main docs for your problem www.PySimpleGUI.org
  • Looked for Demo Programs that are similar to your goal Demos.PySimpleGUI.org
  • If not tkinter - looked for Demo Programs for specific port
  • For non tkinter - Looked at readme for your specific port if not PySimpleGUI (Qt, WX, Remi)
  • Run your program outside of your debugger (from a command line)
  • Searched through Issues (open and closed) to see if already reported Issues.PySimpleGUI.org
  • Tried using the PySimpleGUI.py file on GitHub. Your problem may have already been fixed but not released

Detailed Description

The horizontal_scroll=True property of sg.Listbox element throws an exception in the version 4.60.0.

Error message:
"File "C:\Users\User\AppData\Local\Programs\Python\Python39\lib\site-packages\PySimpleGUI\PySimpleGUI.py", line 15546, in PackFormIntoFrame
element.TKText.config(wrap='none')
AttributeError: 'NoneType' object has no attribute 'config'"

The bug does not depend on the source code, it is related to the version 4.60.0 (I guess the TTK changes)

Code To Duplicate

import PySimpleGUI as sg

sg.Window('Title', [[sg.Listbox([1,2,3,4,5], horizontal_scroll=True)]]).read(close=True)

It should be revised in 4.60.0 for the TTK scrollbars.

Wrong code copy directly from the code for Multiline element.

                # Horizontal scrollbar
                if element.HorizontalScroll:
                    element.TKText.config(wrap='none')        # Wrong statement, wrong widget and wrong option `wrap`, for Listbox element
                    _make_ttk_scrollbar(element, 'h', toplevel_form)
                    element.hsb.pack(side=tk.BOTTOM, fill='x')
                    element.Widget.configure(xscrollcommand=element.hsb.set)

That's a big oops... will make a new pypi dot-release this weekend for this one. Bad thing to have released for sure. Thank you for the great code snippet!

Fixed in 4.60.0.7

Released in 4.60.1 to PyPI on Sunday 22 May 2022.

(Thank you so much for cleaning up the Issues @jason990420 !)
