本文介绍了一个 Qt 自定义控件 UrlView 的实现方法，该控件基于 QTableView 并支持鼠标事件处理及链接激活等功能。通过使用自定义代理和模型，UrlView 能够展示带有超链接的富文本。

#ifndef URLVIEW_H
#define URLVIEW_H

#include <QWidget>
#include <QTableView>


class UrlView : public QTableView
{
    Q_OBJECT
public:
    explicit UrlView(QWidget *parent = nullptr);

protected:
    void mousePressEvent(QMouseEvent *event) override;
    void mouseReleaseEvent(QMouseEvent *event) override;
    void mouseMoveEvent(QMouseEvent *event) override;

    QString anchorAt(const QPoint &pos) const;
signals:
    void linkActivated(QString link);
    void linkHovered(QString link);
    void linkUnhovered();
};

#endif // URLVIEW_H

#include "urlview.h"
#include <QStandardItemModel>

#include <QAbstractTextDocumentLayout>
#include <QHeaderView>
#include <QPainter>
#include <QScrollBar>
#include <QStyledItemDelegate>
#include <QTextDocument>
#include <QLabel>
#include <QTextBlock>

struct Date {
  QString msg;
  QString url;
  QString urlTip;
};

QVector<Date> datas = {
