如何刷新/重新初始化 QStackedWidget 中的小部件

Question

我正在尝试创建一个脚本，使 API 调用网站以获取信息（通过请求模块）。 然后用户可以使用我的脚本/gui 操作网站。

我的应用程序的主要 window 将在底部有几个按钮，它们像选项卡一样在窗口之间切换（为了争论起见，我们说 2 个按钮在两个窗口之间切换）。

当进行某些更改时，我需要 QStackedWidget 刷新某些 windows 中当前未显示的所有小部件/标签。

我的代码摘要：

# Global Variables
app = QApplication(sys.argv)
win = QtWidgets.QStackedWidget()
response = {} # global dict to store API response from website


class UiWindowOne(QMainWindow):
    # This window mostly shows information that I get from the website.
    def __init__(self):
        super(UiWindowOne, self).__init__()
        self.setup_ui(self)
        self.retranslate_ui(self)
        # Then I map buttons to methods
    
    def setup_ui(self, WindowOne):
        # This was generated by QT Designer and places widgets
    
    def retranslate_ui(self, WindowOne):
        # This was generated by QT Designer and places widgets
        
        
    def refresh(self):
        '''
        This function refreshes the current window. Basically, I put everything in the __init__ function in here (except "super(UiWindowOne, self).__init__()".
        :return: None
        '''
        self.setup_ui(self)
        self.retranslate_ui(self)
        # Also map buttons to methods

    


class UiWindowTwo(QMainWindow):
    def __init__(self):
        super(UiWindowTwo, self).__init__()
        self.setup_ui(self)
        self.retranslate_ui(self)
        # Then I map buttons to methods
    
    def setup_ui(self, WindowTwo):
        # This was generated by QT Designer
    
    def retranslate_ui(self, WindowTwo):
        # This was generated by QT Designer
        
        
    def refresh(self):
        '''
        This function refreshes the current window. Basically, I put everything in the __init__ function in here (except "super(UiWindowTwo, self).__init__()".
        :return: None
        '''
        self.setup_ui(self)
        self.retranslate_ui(self)
        # Also map buttons to methods

    def update_website(self):
        # Make changes to website
        # After changes were made, I want to get modified info from the website and re-initialize/refresh both windows to reflect the changes made.
        # I can easily call self.refresh() to refresh WindowTwo. But I cannot refresh WindowOne from here.
        

def main():
    # Here I make API calls to the Website to get info/images
    

    icon = QtGui.QIcon()
    icon.addPixmap(QtGui.QPixmap(".\\imgs/static/A.png"), QtGui.QIcon.Mode.Normal, QtGui.QIcon.State.Off)
    win.setWindowIcon(icon)
    win.setWindowTitle("NAME")
    
    
    first_window = UiWindowOne()
    second_window = UiWindowTwo()
    

    win.addWidget(first_window)
    win.addWidget(second_window)
    

    win.setGeometry(250, 250, 820, 854)
    win.setFixedWidth(820)
    win.setFixedHeight(854)
    win.show()


    sys.exit(app.exec())


if __name__ == '__main__':
    main()      

我曾尝试在 UiWindowTwo 的 update_website() function 下执行“first_window.refresh()”，但随后 python 告诉我未定义 first_window。

然后我尝试制作 first_window 和 second_window 全局变量，但最终我重新排序了我的整个脚本并且无法运行它。

@musicamante，谢谢你提供的信息。 看起来我对 PyQT 的整个方法都是错误的。 我暂时删除了主要的 function，一切正常。 我将按原样完成我当前的脚本，然后尝试通过不编辑 pyuic 文件来按照您的建议进行操作。 我还将研究在 StckedWidget 中不使用 QMainWindow。 谢谢你！
