PyQt5 mp3 阅读

  • 772

我不明白这项工作listwidget，我需要当您单击显示mp3目录中可能的列表项时，一个播放音乐的功能将起作用（例如，通过pyglet或pygame-mixer）

我无法实现它mp3 плеер。

一段带有元素和函数的代码。

     def retranslateUi(self, MainWindow): 
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        __sortingEnabled = self.listWidget.isSortingEnabled()
        self.listWidget.setSortingEnabled(False)
        item=self.listWidget.item(0)
        item.setText(_translate("MainWindow", "New Item")) #Элементы, пришло в голову что можно воспользоваться такой структурой
        item = self.listWidget.item(1)                     #Но я всё равно не знаю как привязать элемент к файлу и как сделать открытие файла.
        item.setText(_translate("MainWindow", "New Item"))
        item = self.listWidget.item(2)
        item.setText(_translate("MainWindow", "New Item"))
        item = self.listWidget.item(3)
        item.setText(_translate("MainWindow", 'w'))
        self.listWidget.setSortingEnabled(__sortingEnabled)


class MainWindow(QMainWindow, Ui_MainWindow):                 
    def __init__(self):                         
        super().__init__()
        
        self.setupUi(self)
        
        self.itemlist = ['Item 1', 'Item 2', 'Item 3', 'Item 4', ] #список из элементов
        self.listWidget.addItems(self.itemlist)
        
        self.listWidget.itemClicked.connect(self.onClicked)
        
    def onClicked(self, item): #При нажатии на элемент срабатывает функция и выводит "0" 
        print('0')```

    1. 更新了班级MainWindow

    2. 导入库pygame

    3. 实现了播放器
