windows - QTableView:如何将鼠标悬停在整行上？

Question

我继承了 QTableView、QAbstractTableModel 和 QItemDelegate。我可以将鼠标悬停在单个单元格上:

void SchedulerDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    ...

    if(option.showDecorationSelected &&(option.state & QStyle::State_Selected))
{
    QColor color(255,255,130,100);
    QColor colorEnd(255,255,50,150);
    QLinearGradient gradient(option.rect.topLeft(),option.rect.bottomRight());
    gradient.setColorAt(0,color);
    gradient.setColorAt(1,colorEnd);
    QBrush brush(gradient);
    painter->fillRect(option.rect,brush);
}

    ...
}

...但我不知道如何悬停整行。有人可以帮我提供示例代码吗？

有两种方法..

1) You can use delegates to draw the row background...
You will need to set the row to highlight in the delegate and based on that, do the highlighting.

2) Catch the signal of current row. Iterate over the items in that row and set background for each item.

你也可以试试样式表:

QTableView::item:hover {
    background-color: #D3F1FC;
}        

希望对大家有用。
