Qt-网易云音乐界面实现-5 收藏列表，播放列表实现 QListWidget QTableWidget

先上目前完成的内容吧，发现后面越写越多。在看看点击量，心凉凉。

完成了左侧的导航列表，还有就是右下角的播放列表。

//创建的歌单
    my_Create_Music_List = new QListWidget(ui->widget_list);
    connect(my_Create_Music_List,&QListWidget::itemClicked,this,&MainWindow::slot_my_Create_Music_List_itemClicked);
    my_Create_Music_List->setStyleSheet("QListWidget{color:rgb(173,175,178); background:rgb(25,27,31);border:0px solid gray;}"
                                        "QListWidget::Item{height:30px;border:0px solid gray;padding-left:15;}"
                                        "QListWidget::Item:hover{color:rgb(255,255,255);background:transparent;border:0px solid gray;}"
                                        "QListWidget::Item:selected{border-image:url(images/listwidget_h.png); color:rgb(255,255,255);border:0px solid gray;}"
                                        "QListWidget::Item:selected:active{background:#00FFFFFF;color:#FFFFFF;border-0;}");
    //去掉滚动条
    my_Create_Music_List->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    my_Create_Music_List->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    my_Create_Music_List->hide();
 
    //创建列表测试
    QListWidgetItem *add_item_10 = new QListWidgetItem(my_Create_Music_List);
    add_item_10->setIcon(QIcon("./images/musicform/btn_like_n.png"));
    add_item_10->setText("我喜欢的音乐");
    QListWidgetItem *add_item_11 = new QListWidgetItem(my_Create_Music_List);
    add_item_11->setIcon(QIcon("./images/lock.png"));
    add_item_11->setText("我的音乐");
 
    QListWidgetItem *add_item_12 = new QListWidgetItem(my_Create_Music_List);
    add_item_12->setIcon(QIcon("./images/musiclist.png"));
    add_item_12->setText("我创建的歌单1");
 
    QListWidgetItem *add_item_13 = new QListWidgetItem(my_Create_Music_List);
    add_item_13->setIcon(QIcon("./images/musiclist.png"));
    add_item_13->setText("我创建的歌单2");
 
    QListWidgetItem *add_item_14 = new QListWidgetItem(my_Create_Music_List);
    add_item_14->setIcon(QIcon("./images/musiclist.png"));
    add_item_14->setText("我创建的歌单3");
 
 
 
    //收藏的歌单
    my_Collect_Music_List = new QListWidget(ui->widget_list);
    connect(my_Collect_Music_List,&QListWidget::itemClicked,this,&MainWindow::slot_my_my_Collect_Music_List_itemClicked);
    my_Collect_Music_List->setStyleSheet("QListWidget{color:rgb(173,175,178); background:rgb(25,27,31);border:0px solid gray;}"
                                         "QListWidget::Item{height:30px;border:0px solid gray;padding-left:15;}"
                                         "QListWidget::Item:hover{color:rgb(255,255,255);background:transparent;border:0px solid gray;}"
                                         "QListWidget::Item:selected{border-image:url(images/listwidget_h.png); color:rgb(255,255,255);border:0px solid gray;}"
                                         "QListWidget::Item:selected:active{background:#00FFFFFF;color:#FFFFFF;border-0;}");
    //去掉滚动条
    my_Collect_Music_List->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    my_Collect_Music_List->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    my_Collect_Music_List->hide();
 
    //收藏歌单测试
    QListWidgetItem *add_item_15 = new QListWidgetItem(my_Collect_Music_List);
    add_item_15->setIcon(QIcon("./images/musiclist.png"));
    add_item_15->setText("我收藏的歌单1");
 
    QListWidgetItem *add_item_16 = new QListWidgetItem(my_Collect_Music_List);
    add_item_16->setIcon(QIcon("./images/musiclist.png"));
    add_item_16->setText("我收藏的歌单2");
 
    QListWidgetItem *add_item_17 = new QListWidgetItem(my_Collect_Music_List);
    add_item_17->setIcon(QIcon("./images/musiclist.png"));
    add_item_17->setText("我收藏的歌单3");

　　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

/*
 * 创建列表展开列表
 */
static bool unfold_Flag = false;
void MainWindow::on_pushButton_unfold_clicked()
{
    if(!unfold_Flag)
    {

        ui->widget_list->resize(200,ui->widget_list->height() + 30*my_Create_Music_List->count());
        ui->widget_Collect_form->setGeometry(0,my_Create_Music_List->y()+30*my_Create_Music_List->count(),200,30);
        if(!my_Collect_Music_List->isHidden())

        ui->widget_list->resize(200,ui->widget_list->height() - 30*my_Create_Music_List->count());

        if(!my_Collect_Music_List->isHidden())
        {
            my_Collect_Music_List->setGeometry(0,ui->widget_Collect_form->y()+30,200,30*my_Collect_Music_List->count());
        }
    }
 
}
/*

static bool unfold_collect_Flag = false;
void MainWindow::on_pushButton_unfold_collect_clicked()

    if(!unfold_collect_Flag)
    {

                                                     "QPushButton::pressed{border-image:url(images/btn_down_n.png);}");
        ui->widget_list->resize(200,ui->widget_list->height() + 30*my_Create_Music_List->count());
 
 
    }
    else

        ui->widget_list->resize(200,ui->widget_list->height() - 30*my_Create_Music_List->count());
    }
 
}

　　剩下的就是右侧的这个播放列表了，这个就是用了一个tabwidget来显示播放列表和历史记录

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
