Question

我想设置一个自定义QHeaderView来旋转水平标题的文本。我正在使用QStandarItemModel

目前我已经

了

class QHeaderViewR : public QHeaderView
{
public:
    QHeaderViewR():QHeaderView(Qt::Horizontal)
    {}

    void paintSection(QPainter * painter, const QRect & rect, int logicalIndex) const
    {
      QPen pen(Qt::black);
      painter->setPen(pen);
      painter->translate(rect.width() * logicalIndex, (logicalIndex * -18) -18);
      painter->rotate(90);
      painter->drawText(rect,"header");
    }
};

我真的不明白我对翻译做了什么。我只是试验和错误，直到它与列有些匹配。它仍然没有完美地做到这一点，它没有明显的理由削减文本。我应该怎么做才能使文字与列匹配而不被切断？

"pic of the mismatch and cut text"

另一件事是我不想只在每一列上写“标题”。要查看的模型将HorizontalHeaderItem分配给每一列，我想显示这些标题

提前感谢您的帮助

我解决了。只需添加一个QStringList作为构造函数的参数，并使用逻辑索引迭代它。这是最终结果

class QHeaderViewR : public QHeaderView
{
QStringList heads;

public:
    QHeaderViewR(QStringList _heads):QHeaderView(Qt::Horizontal)
    {

        heads = _heads;
    }

    void paintSection(QPainter * painter, const QRect & rect, int logicalIndex) const
    {


        QPen pen(Qt::black);
        painter->setPen(pen);

        painter->rotate(90);
        painter->translate(0,-rect.width()+1);

        QRect copy = rect;

        copy.setWidth(rect.height());
        copy.setHeight(rect.width());
        copy.moveTo(0,-this->sectionPosition(logicalIndex));

        if (logicalIndex == 0)
        {
            copy.setHeight(rect.width()-1);
        }

        painter->drawText(copy, " " + heads.at(logicalIndex));
        painter->drawRect(copy);
    }
};

由于QHeaderView只是一个视图，您应该从模型中获取数据。

所以，类似于base implementation in QHeaderView：

QStandardItemModel::setHorizontalHeaderLabels(const QStringList &labels)

要在模型上设置标题，请使用例如
