PySimpleGui 中的文本未更新

Text not updating in PySimpleGui

在我的代码中,我正在尝试制作一个计算器。所以有一个 1 按钮,当按下它时,通过将 1 添加到它的文本来更新 Question: 文本。所以当我按下 1 时,文本将从 Question: 转换为 Question: 1。但它没有更新。我以前也遇到过这个问题。我想当我执行 .update 时,它只会更新值,直到它的字母数与文本已有的字母数相同。如果它有 2 个字母并且我尝试 .update('123'),它只会更新为 12。有什么办法可以解决这个问题吗???

import PySimpleGUI as sg

layout = [
    [sg.Text('Question: ', key='-IN-')],
    [sg.Text('Answer will be shown here', key='-OUT-')],
    [sg.Button('1'), sg.Button('2'), sg.Button('3')],
    [sg.Button('4'), sg.Button('5'), sg.Button('6')],
    [sg.Button('7'), sg.Button('8'), sg.Button('9')],
    [sg.Button('Enter'), sg.Button('Exit')]
]

window = sg.Window('calculator', layout)

while True:
    event, values = window.read()
    if event is None or event == 'Exit':
        break
    elif event == '1':
        bleh = window['-IN-'].get()
        teh = f'{bleh}1'
        window['-IN-'].update(value=teh)

window.close()

如上评论,例子是这样的,

import PySimpleGUI as sg

layout = [
    [sg.InputText('Question: ', readonly=True, key='-IN-')],
    [sg.Text('Answer will be shown here', key='-OUT-')],
    [sg.Button('1'), sg.Button('2'), sg.Button('3')],
    [sg.Button('4'), sg.Button('5'), sg.Button('6')],
    [sg.Button('7'), sg.Button('8'), sg.Button('9')],
    [sg.Button('Enter'), sg.Button('Exit')]
]

window = sg.Window('calculator', layout)
input = window['-IN-']
while True:
    event, values = window.read()
    if event is None or event == 'Exit':
        break
    elif event in '1234567890':
        bleh = window['-IN-'].get()
        teh = f'{bleh}{event}'
        input.update(value=teh)
        input.Widget.xview("end")   # view end if text is too long to fit element

window.close()
