[英]How Refresh/Re-initialize Widgets in QStackedWidget
我正在嘗試創建一個腳本,使 API 調用網站以獲取信息(通過請求模塊)。 然后用戶可以使用我的腳本/gui 操作網站。
我的應用程序的主要 window 將在底部有幾個按鈕,它們像選項卡一樣在窗口之間切換(為了爭論起見,我們說 2 個按鈕在兩個窗口之間切換)。
當進行某些更改時,我需要 QStackedWidget 刷新某些 windows 中當前未顯示的所有小部件/標簽。
我的代碼摘要:
# 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()
我曾嘗試在 UiWindowTwo 的 update_website() function 下執行“first_window.refresh()”,但隨后 python 告訴我未定義 first_window。
然后我嘗試制作 first_window 和 second_window 全局變量,但最終我重新排序了我的整個腳本並且無法運行它。
@musicamante,謝謝你提供的信息。 看起來我對 PyQT 的整個方法都是錯誤的。 我暫時刪除了主要的 function,一切正常。 我將按原樣完成我當前的腳本,然后嘗試通過不編輯 pyuic 文件來按照您的建議進行操作。 我還將研究在 StckedWidget 中不使用 QMainWindow。 謝謝你!
