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. It is recommend you use the Demo Browser! 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
• Have upgraded to the latest release of PySimpleGUI on PyPI (lastest official version)
• Tried using the PySimpleGUI.py file on GitHub. Your problem may have already been fixed but not released

Detailed Description

I'm sending a document to a Multiline Element that has embedded tabs(\t). The original doc shows these as four spaces. The Multiline Element shows these as eight spaces. I'd like to see an option to choose the tab_size i.e. tab_size=4.

Code To Duplicate

A short program that isolates and demonstrates the problem (Do not paste your massive program, but instead 10-20 lines that clearly show the problem)

This pre-formatted code block is all set for you to paste in your bit of code:

sg.Multiline(size=(40, 14), key="-BEFORE-")

window["-BEFORE-"].update(r.get_before())

Wow! I forgot about those other answers entirely. If this is a duplicate, I'll take the blame for it as I send @casmithac here to open a request.

I was experimenting with an oversimplified attempt at setting tabs to be 4 spaces but didn't have very good luck.

# in the layout
        [sg.Multiline(key='-ML-', s=(60,10), )],

# later...
        window['-ML-'].widget.config(tabs=sg.Text.char_width_in_pixels(window['-ML-'].widget['font'], ' ')*4)

It's not as easy as I would have hoped it would be. It would be a nice parameter to add to Multiline for inputs. I definitely see where it would be useful to have 4 char tabs for a text editor application for example.

@casmithac - WOW you've got SOOOOOOOOOOOOO much experience in this craft. Love it
that you're using PySimpleGUI! Thanks for taking the time to fill out the request.
