在本文中，您将学习如何创建一个PyQt5消息框

import sys
    from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QMessageBox
    from PyQt5.QtGui import QIcon
    from PyQt5.QtCore import pyqtSlot
    
    class App(QWidget):
        
        def __init__(self):
            super().__init__()
            self.title = 'PyQt5 messagebox - pythonspot.com'
            self.left = 10
            self.top = 10
            self.width = 320
            self.height = 200
            self.initUI()
        
        def initUI(self):
            self.setWindowTitle(self.title)
            self.setGeometry(self.left, self.top, self.width, self.height)
            """使用方法QMessageBox.question()来显示消息框"""
            """参数：处于哪个控件内    消息框标题    消息内容    按钮内容    默认选择按钮"""
            buttonReply = QMessageBox.question(self, "PyQt5 message", "Do you like PyQt5?", 
                                               QMessageBox.Yes | QMessageBox.No, QMessageBox.No)
            if buttonReply == QMessageBox.Yes:
                print("Yes clicked!")
            else:
                print("No clicked!")
            
            self.show()
    
    if __name__ == "__main__":
        app = QApplication(sys.argv)
        ex = App()
        sys.exit(app.exec_())

消息框按钮概括：
