这里就是现在是用了4个listwidget ，需要再每个的触发函数中把其他三个的数据屏蔽了，不知道网易原生是不是这样实现的。 

/*
 * 推荐列表
void MainWindow::on_listWidget_itemClicked(QListWidgetItem *item)





    
    Q_UNUSED(item);
//    qDebug()<<item->text();
    ui->listWidget_mymusic->clearSelection();
    my_Collect_Music_List->clearSelection();
    my_Create_Music_List->clearSelection();
 * 我的音乐列表
void MainWindow::on_listWidget_mymusic_itemClicked(QListWidgetItem *item)
    Q_UNUSED(item);
//    qDebug()<<item->text();
    ui->listWidget->clearSelection();
    my_Collect_Music_List->clearSelection();
    my_Create_Music_List->clearSelection();
 * 我创建的列表点击
void MainWindow::slot_my_Create_Music_List_itemClicked(QListWidgetItem *item)
    Q_UNUSED(item);
//    qDebug()<<item->text();
    ui->listWidget_mymusic->clearSelection();
    ui->listWidget->clearSelection();
    my_Collect_Music_List->clearSelection();
 * 我收藏的列表点击
void MainWindow::slot_my_my_Collect_Music_List_itemClicked(QListWidgetItem *item)
    Q_UNUSED(item);
//    qDebug()<<item->text();
    ui->listWidget_mymusic->clearSelection();
    ui->listWidget->clearSelection();
    my_Create_Music_List->clearSelection();
}

可以看下，这里就是间的把每个listwidget的最后一个选项取消。

还存在一个问题就是创建的歌单和收藏的歌单

这里就是用了简单的位置移动

主要的还是qss的问题，这里还有很多细节没有实现，不过没有耐心了，暂时这样吧。

看下整个代码

}

这些接口都还没有引出来，如果要实现功能，需要将接口引出。

好了，今天就到了这里吧，都哈哈
