AttributeError: 'tuple' object has no attribute 'ParentContainer'

Question

我是 python 的初学者并且正在使用 PySimpleGUI，但我一直收到此错误并且无法弄清楚原因。欢迎帮助...

错误是：

Traceback (most recent call last):
  File "/Users/georgeknight/pythonProject/Metrics.py", line 17, in <module>
[tm_number], [sg.Column(col1)], [sg.Column(col2)],
  File "/Users/georgeknight/pythonProject/venv/lib/python3.10/site-packages/PySimpleGUI/PySimpleGUI.py", line 7811, in __init__
self.Layout(layout)
  File "/Users/georgeknight/pythonProject/venv/lib/python3.10/site-packages/PySimpleGUI/PySimpleGUI.py", line 7893, in layout
self.AddRow(*row)
  File "/Users/georgeknight/pythonProject/venv/lib/python3.10/site-packages/PySimpleGUI/PySimpleGUI.py", line 7851, in add_row
    if element.ParentContainer is not None:
AttributeError: 'tuple' object has no attribute 'ParentContainer'

这是我的代码：

import PySimpleGUI as sg

tm_number = sg.Text("Technical Manual Number:",  font=(24,24)),
            sg.Input(key='tm_number', font=(24,24), size=(48,24))
review = sg.Text("Type of Review:",  font=(24,24)),
         sg.Input(key='review', font=(24,24), size=(12,24))
pages = sg.Text("Number of Pages: ",  font=(24,24)),
        sg.Input(key='pages', font=(24,24), size=(6,24))
submission_date = sg.Text("Date of Submission: ",  font=(24,24)),
                  sg.Input(key='submission_date', font=(24,24), size=(12,24))
writer = sg.Text("Writer's Name: ",  font=(24,24)),
         sg.Input(key='writer', font=(24,24), size=(24,24))
col1 = [[review], [submission_date]]
col2 = [[writer], [pages]]

layout = [[sg.Text("Writer's Submission Form", font=(48,48))],
          [tm_number], [sg.Column(col1), sg.Column(col2)],
          [sg.Button("SUBMIT FOR REVIEW", size=(24,1), font=24)]]

window = sg.Window("Technical Manual Engineering Review (TMER)", layout)

event, values = window.read()

window.close

我正在尝试构建一个简单的 GUI，顶部带有变量“tm_number”，然后是 2 列：一列带有变量“review”和“submission_date”，另一列带有“writer”和“pages”。该按钮应该位于窗口的右下角（还没有那么远）。

Answer 1

c = a, b    # c = (a, b)
d = [c]     # d = [(a, b)], not [a, b]

检查布局格式是否为

List[List[Element]] | Tuple[Tuple[Element]]

.

import PySimpleGUI as sg

tm_number       = [sg.Text("Technical Manual Number:",  font=(24,24)), sg.Input(key='tm_number', font=(24,24), size=(48,24))]
review          = [sg.Text("Type of Review:",  font=(24,24)), sg.Input(key='review', font=(24,24), size=(12,24))]
pages           = [sg.Text("Number of Pages: ",  font=(24,24)), sg.Input(key='pages', font=(24,24), size=(6,24))]
submission_date = [sg.Text("Date of Submission: ",  font=(24,24)),sg.Input(key='submission_date', font=(24,24), size=(12,24))]
writer          = [sg.Text("Writer's Name: ",  font=(24,24)), sg.Input(key='writer', font=(24,24), size=(24,24))]
col1            = [review, submission_date]
col2            = [writer, pages]

layout = [
    [sg.Text("Writer's Submission Form", font=(48,48))],
     tm_number,
    [sg.Column(col1), sg.Column(col2)],
    [sg.Button("SUBMIT FOR REVIEW", size=(24,1), font=24)],
]
window = sg.Window("Technical Manual Engineering Review (TMER)", layout).read(close=True)
