我正在尝试创建一个脚本，该脚本对网站进行 API 调用以获取信息（通过请求模块）。然后用户可以使用我的脚本/gui 来操作网站。
我的应用程序的主窗口底部有几个按钮，它们的作用类似于在窗口之间切换的选项卡（为了论证的缘故，假设有 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 来刷新当前未显示的某些窗口中的所有小部件/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() 函数下执行“first_window.refresh()”，但随后 python 告诉我 first_window 未定义。
然后我尝试制作 first_window 和 second_window 全局变量，但后来我重新排序了我的整个脚本并且无法让它运行。
