我對蟒蛇和PyQt5很陌生。我的目標是使用“按鈕”移動到“堆疊布局”中的下一個小部件。但是，它沒有響應，并且似乎不會進入函數以移動到下一個小部件。我不知道是我搞砸了的遺產，還是別的什么。任何指導都非常感謝。謝謝！from PyQt5 import QtCore, QtGui, QtWidgetsclass Menu(QtWidgets.QWidget): def setupUI(self, Main): Main.setObjectName("Main") Main.setFixedSize(900, 500) self.width = 900 self.height = 500 self.setFixedSize(self.width, self.height) self.menu = QtWidgets.QStackedLayout() self.welcomeMenu = QtWidgets.QWidget() self.mainMenu = QtWidgets.QWidget() self.welcomeUi() self.menuUi() self.menu.addWidget(self.welcomeMenu) self.menu.addWidget(self.mainMenu) def welcomeUi(self): #Button for entering portal self.entrBtn = QtWidgets.QPushButton(self.welcomeMenu) self.entrBtn.setGeometry(QtCore.QRect(25,150,200,50)) self.entrBtn.setText("To the menu screen!") #Having welcome text self.welcomeText = QtWidgets.QLabel(self.welcomeMenu) self.welcomeText.setGeometry(QtCore.QRect(30, 120, 480, 200)) self.welcomeText.setAlignment(QtCore.Qt.AlignLeading|QtCore.Qt.AlignLeft|QtCore.Qt.AlignTop) self.welcomeText.setText("Welcome!") def menuUi(self): self.text = QtWidgets.QLabel(self.mainMenu) self.text.setGeometry(QtCore.QRect(30, 120, 480, 200)) self.text.setText("test")class Main(QtWidgets.QMainWindow, Menu): def __init__(self): super(Main, self).__init__() self.setupUI(self) self.entrBtn.clicked.connect(self.menuWindow) def menuWindow(self): self.menu.setCurrentWidget(self.mainMenu)if __name__ == "__main__": import sys app = QtWidgets.QApplication(sys.argv) m = Main() sys.exit(app.exec_())

問題很簡單：QLabel位于按鈕的頂部，因此它將阻止所有鼠標事件。簡單的解決方案是使用raise_（）將QPushButton放在Q標簽上：
# ...
self.welcomeText.setText("Welcome!")
self.entrBtn.raise_()
但這解決了表面的問題，你還有其他更大的問題：你不應該繼承2 QWidget，也沒有顯示Main。最好按如下方式重寫代碼：
from PyQt5 import QtCore, QtGui, QtWidgets
class MainWindow(QtWidgets.QMainWindow):
def __init__(self, parent=None):
super().__init__(parent)
self.welcomeMenu = QtWidgets.QWidget()
self.mainMenu = QtWidgets.QWidget()
self.fill_welcomeUi()
self.fill_menuUi()
self.stacked_lay = QtWidgets.QStackedLayout()
self.stacked_lay.addWidget(self.welcomeMenu)
self.stacked_lay.addWidget(self.mainMenu)
central_widget = QtWidgets.QWidget()
self.setCentralWidget(central_widget)
central_widget.setLayout(self.stacked_lay)
self.entrBtn.clicked.connect(self.menuWindow)
self.resize(640, 480)
def menuWindow(self):
self.stacked_lay.setCurrentWidget(self.mainMenu)
def fill_welcomeUi(self):
#Button for entering portal
self.entrBtn = QtWidgets.QPushButton(self.welcomeMenu)
self.entrBtn.setGeometry(QtCore.QRect(25,150,200,50))
self.entrBtn.setText("To the menu screen!")
#Having welcome text
self.welcomeText = QtWidgets.QLabel(self.welcomeMenu)
self.welcomeText.setGeometry(QtCore.QRect(30, 120, 480, 200))
self.welcomeText.setAlignment(QtCore.Qt.AlignLeading|QtCore.Qt.AlignLeft|QtCore.Qt.AlignTop)
self.welcomeText.setText("Welcome!")
self.entrBtn.raise_()
def fill_menuUi(self):
self.text = QtWidgets.QLabel(self.mainMenu)
self.text.setGeometry(QtCore.QRect(30, 120, 480, 200))
self.text.setText("test")
if __name__ == "__main__":
import sys
app = QtWidgets.QApplication(sys.argv)
m = MainWindow()
m.show()
sys.exit(app.exec_())
