我正在嘗試構(gòu)建一個(gè)基于 python 的軟件。（基于 PYQT 的軟件）問(wèn)題：我的第二個(gè)窗口在打開(kāi)后立即關(guān)閉。問(wèn)題：我的代碼有問(wèn)題嗎？我如何解決它？注意：?jiǎn)螕糸_(kāi)始按鈕時(shí)會(huì)打開(kāi)第二個(gè)窗口。這是我的代碼：class MainWindow(QMainWindow): switch_window=pyqtSignal(str) def __init__(self): super().__init__() self.initUI() def initUI(self): #Initialize self.setGeometry(1000, 300, 1200, 800) self.setWindowTitle('Sensorlyze') self.setWindowIcon(QIcon('biosensor.jpg')) icon = QIcon('biosensor.jpg') # Add Text l1= QLabel("Welcome to SensorLyze",self) l1.move(25, 350) # l1.setWordWrap(True) l1.setFont(QFont('Calibri',15)) l1.adjustSize() l2 = QLabel("A software to simply sensor analytics", self) l2.move(25, 400) l2.setFont(QFont('Calibri', 10)) l2.adjustSize() #Add Buttons button1 = QPushButton('Start',self) button1.resize(button1.sizeHint()) button1.clicked.connect(start_clicked) button1.move(60, 450) button2 = QPushButton('Exit', self) button2.resize(button2.sizeHint()) button2.clicked.connect(exit_clicked) button2.move(240, 450)stylesheet = """ QMainWindow { background-image: url("C:/Users/admin/Desktop/Sensorlyze/biosensor.jpg"); background-repeat: no-repeat; background-position: center; }"""# def switch(self):# self.switch_window.emit(self.line_edit.text())def start_clicked(): window=QMainWindow() window.setGeometry(300, 500, 500, 500) window.setWindowTitle('Hello') window.show() win.hide()def exit_clicked(): msgBox=QMessageBox() msgBox.setIcon(QMessageBox.Information) msgBox.setText("Are you sure you want to exit?") msgBox.setWindowTitle("Exit Sensorlyze") msgBox.setStandardButtons(QMessageBox.Ok|QMessageBox.Cancel) msgBox.buttonClicked.connect(msgButtonClick) returnValue = msgBox.exec() if returnValue==QMessageBox.Ok: exit()def msgButtonClick(i): print("Buttonclickedis:",i.text())我在這里錯(cuò)過(guò)了什么嗎？任何幫助...
