QListWidget 使用

1、QListWidget 插入Qwidget

QListWidgetItem *widgetItem = new QListWidgetItem(ui->listWidget);
widgetItem->setSizeHint(QSize(94, 48));
ui->listWidget->addItem(widgetItem);
WgFriendList*  wgFriend = new WgFriendList(　　this);
ui->listWidget->setItemWidget(widgetItem, wgFriend);

WgFriendList继承字QWidget。上述将一个窗口放入QListWidget的行中。

2、双击item项

void OnItemDoubleClicked(QListWidgetItem * item)
{
    int nIndex = ui->listWidget->currentIndex().row();
    qDebug() << "OnItemDoubleClicked" << nIndex;

    QWidget*  wg = ui->listWidget->itemWidget(item);
    WgPersonInfo* wgPi = (WgPersonInfo*)wg;
}

 

3、QListWidget 鼠标划过，按下背景色改变

QListWidget
{    
    background-color: rgba(0,108,255, 0.2);
    color:white;
    font-family:Microsoft YaHei;
}
QListWidget::Item
{
    border-bottom:1px solid rgba(0,106,255,0.5);
}

QListWidget::Item:hover
{
    background:rgba(0,191,255,0.3);
    font-family:Microsoft YaHei;
}

QListWidget::Item:selected

    background:rgba(0,191,255,0.8);
