嵌套时 PysimpleGui 按钮不起作用

Question

这是我的代码：

import PySimpleGUI as sg

layout1 = [[sg.Button('New', "center")], [sg.Button("Load Save", "center")]]
layout2 = [[sg.Text("2nd Page")], [sg.Button("New Page", "center")], [sg.Button("Load Page", "center")]]

layout = [[sg.Column(layout1, key='-COL1-'), sg.Column(layout2, visible=False, key='-COL2-')]]

window = sg.Window('ORIGINAL').Layout(layout)

while True:             # Event Loop
    event, values = window.Read()
    if event in (None, 'Exit'):
        break
    if event == 'New':
        print("hello")
    elif event == '2':
        print("hello 2")
window.Close()

当我点击按钮时没有任何反应。如果我将这些按钮放在布局中（而不是 layout1 或 layout2），它们就可以完美工作。所以我的问题是如何让这些按钮正常工作，同时将它们留在原处？

对不起，如果这是一个愚蠢的问题，我是 pysimplegui 的新手

问题不在于按钮元素的位置，而在于您向 sg.Button 提供的参数。

sg.Button 定义为

class Button(Element):
    """
    Button Element - Defines all possible buttons. The shortcuts such as Submit, FileBrowse, ... each create a Button
    """

    def __init__(self, button_text='', button_type=BUTTON_TYPE_READ_FORM, target=(None, None), tooltip=None,
                 file_types=(("ALL Files", "*.*"),), initial_folder=None, default_extension='', disabled=False, change_submits=False,
                 enable_events=False, image_filename=None, image_data=None, image_size=(None, None),
                 image_subsample=None, border_width=None, size=(None, None), s=(None, None), auto_size_button=None, button_color=None,
                 disabled_button_color=None,
                 highlight_colors=None, mouseover_colors=(None, None), use_ttk_buttons=None, font=None, bind_return_key=False, focus=False, pad=None, key=None,
                 k=None, right_click_menu=None, expand_x=False, expand_y=False, visible=True, metadata=None):

当您将参数传递给 sg.Button 时省略了关键字，第二个参数将是 button_type，不确定您为什么给出 'center'。除了 button_text、key 或 key 之外，显然没有任何其他参数可以具有这样的值 'center'.

import PySimpleGUI as sg

layout1 = [
    [sg.Button('New')],
    [sg.Button('Load')],
    [sg.Button('Save')],
]

layout2 = [
    [sg.Text("2nd Page")],
    [sg.Button("New Page")],
    [sg.Button("Load Page")],
]

layout = [
    [sg.Column(layout1, key='-COL1-'),
     sg.Column(layout2, visible=False, key='-COL2-')],
]

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

while True:

    event, values = window.read()

    if event  == sg.WINDOW_CLOSED:
        break
    elif event == 'New':
        print("Hello New")
    elif event == 'Load':
        print("Hello Load")
    elif event == 'Save':
        print("Hello Save")

window.close()
