网易云音乐UI界面

接着上期的网易云音乐搜索和下载，现在再添加一个功能。用pyqt5制作一个UI界面
效果展示：
在这里插入图片描述
主窗口中有个控件：行编辑输入框、搜索按钮、表格

代码解释

自定义标签

  1. class MyQLabel(QLabel):...

重写鼠标事件

  1. def mouseReleaseEvent(self, QMouseEvent):
  2.         self.clicked_signal.emit()

发送信号，当标签被点击了调用相应的事件

  1. def connect(self, callback):
  2.         self.clicked_signal.connect(callback)

主窗口类
