猜数字小游戏

总结：

1。下面这行代码用于点击关闭的时候提示弹窗；

def closeEvent(self, event):
        reply = QMessageBox.question(self, '确认', '确认退出吗？', QMessageBox.Yes|QMessageBox.No)
        if reply == QMessageBox.Yes:
            event.accept()
        else:
            event.ignore()

遗留问题：机制还不是很清楚，还有，为什么只是定义了一个方法，而没有调用呢？

 

2.怎么判断输入为空？

原来的程序它没写完

def gass(self):
        number = int(self.lineEdit.text())
        # if self.lineEdit.text().isEmpty():
        #     QMessageBox.about(self, '警告', '必须输入一个0-10的数字！')
        #     self.lineEdit.clear()
        #     self.lineEdit.setFocus()
        if number > self.num:
            QMessageBox.about(self, '结果', '猜大了！')
            self.textEdit.append(self.lineEdit.text()+' 猜大了！')
            self.lineEdit.clear()
            self.lineEdit.setFocus()
        elif number < self.num:
            QMessageBox.about(self, '结果', '猜小了！')
            self.textEdit.append(self.lineEdit.text()+' 猜小了！')
            self.lineEdit.clear()
            self.lineEdit.setFocus()
        elif number == self.num:
            QMessageBox.about(self, '结果', '恭喜你猜对了！')
            self.textEdit.append(self.lineEdit.text())
            self.num = random.randint(0,10)
            print(self.num)
            self.lineEdit.clear()
            self.textEdit.clear()
            self.lineEdit.setFocus()
        else:
            pass

我改了一下：

    def gass(self):
        number = self.lineEdit.text()
        if number == '':
            QMessageBox.about(self, '警告', '必须输入一个0-10的数字！')
            self.textEdit.append(' 必须输入一个0-10的数字！')
            self.lineEdit.clear()
            self.lineEdit.setFocus()
        else:
            number=int(number)
            if number > self.num:
                QMessageBox.about(self, '结果', '猜大了！')
                self.textEdit.append(self.lineEdit.text()+' 猜大了！')
                self.lineEdit.clear()
                self.lineEdit.setFocus()
            elif number < self.num:
                QMessageBox.about(self, '结果', '猜小了！')
                self.textEdit.append(self.lineEdit.text()+' 猜小了！')
                self.lineEdit.clear()
                self.lineEdit.setFocus()
            elif number == self.num:
                QMessageBox.about(self, '结果', '恭喜你猜对了！')
                self.textEdit.append(self.lineEdit.text())
                self.num = random.randint(0,10)
                print(self.num)
                self.lineEdit.clear()
                self.textEdit.clear()
                self.lineEdit.setFocus()
            else:
                pass
