如何在悬停时更改QTreewidget标题背景

class CustomTreeWidgetItem : public QTreeWidgetItem {
public:
    CustomTreeWidgetItem(QTreeWidget* parent) : QTreeWidgetItem(parent) {}
    
    void paint(QPainter* painter, const QStyleOptionViewItem& option, int column) const override {
        if (option.state & QStyle::State_MouseOver) {
            painter->fillRect(option.rect, Qt::yellow); // 更改标题背景色
        }
        QTreeWidgetItem::paint(painter, option, column);
    }
};

QTreeWidget* treeWidget = new QTreeWidget(this);
CustomTreeWidgetItem* item1 = new CustomTreeWidgetItem(treeWidget);
item1->setText(0, "Item 1");
// 添加更多的自定义QTreeWidgetItem项

treeWidget->addTopLevelItem(item1);
// 添加更多的顶级项
