[Question] PySide cannot accept a list of objects as the values for the Combobox element

從 PySimpleGUIQt.py 中 Combo 的更新路徑開始，找到呼叫 self.QT_ComboBox.addItems(values) 的位置，並將其與處理物件值的初始化路徑進行比較。執行提供的 Point 重現程式，並確認使用物件更新 Combo 時顯示的是它們的字串值，而不是空白行。

Troubleshooting

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

• Searched main docs for your problem PySimpleGUI Documenation
• Looked for Demo Programs that are similar to your goal. It is recommend you use the Demo Browser! Demo Programs
• None of your GUI code was generated by an AI algorithm like GPT
• 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.com
• Have upgraded to the latest release of PySimpleGUI on PyPI (lastest official version)
• Tried running the Development Build. Your problem may have already been fixed but not released. Check Home Window for release notes and upgrading capability
• For licensing questions please email license@PySimpleGUI.com

Detailed Description

PySide2.QtWidgets.QComboBox.addItems(texts)

Parameters:

texts – list of strings

PySimpleGUI/tkinter can accept objects as values of widget, but PySimpleGUIQt/PySide cannot.

• Source code when initiate a Combobox, and it's fine.

items_as_strings = [str(v) for v in element.Values]
# element.QT_ComboBox.addItems(element.Values)
element.QT_ComboBox.addItems(items_as_strings)

• Source code when update a Combobox

self.QT_ComboBox.addItems(values)

You can find that there's no code to converts values to a list of str in PySimpleGUIQt.py when update, so we need to do it by ourself, or new values will be shown as blank lines in the Combobox element after updated.

Code To Duplicate

import PySimpleGUIQt as sg

class Point:
    def __init__(self, location) -> None:
        self.location = location

    def __str__(self) -> str:
        return f"Location {self.location}"

points = [Point(i) for i in range(5)]

window = sg.Window("Title", [[sg.Combo([0,1,2,3,4], key='COMBO')]], finalize=True)
window['COMBO'].update(values=points)
# window['COMBO'].update(values=tuple(map(str, points)))
window.read(close=True)
