下面是主要实现

继承自 QItemDelegate

主要是实现 了它的painter方法，把两个自定义的按钮绘制到视图并保存

还有editorEvent事件，用来处理点击事件，在点击时我们算一下鼠标的坐标在哪个按钮下，

再处理相应的点击事件

#ifndef BUTTONDELEGATE_H

#define BUTTONDELEGATE_H

#include <QItemDelegate>

class ButtonDelegate : public QItemDelegate

{

    Q_OBJECT

public:

    explicit ButtonDelegate(QObject *parent = );

    void paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const;

    bool editorEvent(QEvent *event, QAbstractItemModel *model, const QStyleOptionViewItem &option, const QModelIndex &index);

signals:

    void showMsg(QString str);

    typedef QMap<QModelIndex, QPair<QStyleOptionButton*, QStyleOptionButton*>* >  collButtons;

    collButtons m_btns;

};

#endif // BUTTONDELEGATE_H

        button2->text = "Y";

        button2->state |= QStyle::State_Enabled;

        buttons =new  QPair<QStyleOptionButton*, QStyleOptionButton*>(button1, button2);

        (const_cast<ButtonDelegate *>(this))->m_btns.insert(index, buttons);

    }

    buttons->first->rect = option.rect.adjusted(, , -(option.rect.width() /  + ) , -); //

    painter->save();

    if (option.state & QStyle::State_Selected) {

    }

    painter->restore();

    QApplication::style()->drawControl(QStyle::CE_PushButton, buttons->first, painter);

    QApplication::style()->drawControl(QStyle::CE_PushButton, buttons->second, painter);

}

bool ButtonDelegate::editorEvent(QEvent *event, QAbstractItemModel *model, const QStyleOptionViewItem &option, const QModelIndex &index)

{

    if (event->type() == QEvent::MouseButtonPress) {

        QMouseEvent* e =(QMouseEvent*)event;

        if (m_btns.contains(index)) {

            QPair<QStyleOptionButton*, QStyleOptionButton*>* btns = m_btns.value(index);

            }

                btns->second->state |= QStyle::State_Sunken;

            }

        }

    }

    if (event->type() == QEvent::MouseButtonRelease) {

        QMouseEvent* e =(QMouseEvent*)event;

        if (m_btns.contains(index)) {

            QPair<QStyleOptionButton*, QStyleOptionButton*>* btns = m_btns.value(index);

            if (btns->first->rect.contains(e->x(), e->y())) {

                btns->first->state &= (~QStyle::State_Sunken);

                showMsg(tr("btn1 column %1").arg(index.column()));

            } else if(btns->second->rect.contains(e->x(), e->y())) {

                btns->second->state &= (~QStyle::State_Sunken);

                showMsg(tr("btn2 row %1").arg(index.row()));

            }

        }

    }

}

void ButtonDelegate::showMsg(QString str)

{

    QMessageBox msg;

    msg.setText(str);

    msg.exec();

}

好了自定义按钮处理完了

    Qt::ItemFlags flag = QAbstractItemModel::flags(index);

    // flag|=Qt::ItemIsEditable // 设置单元格可编辑,此处注释,单元格无法被编辑

    return flag;

}

void TableModel::setHorizontalHeader(const QStringList &headers)

{

    m_HorizontalHeader =  headers;

}

QVariant TableModel::headerData(int section, Qt::Orientation orientation, int role) const

{

    if (role == Qt::DisplayRole && orientation == Qt::Horizontal) {

        return m_HorizontalHeader.at(section);

    }

    return QAbstractTableModel::headerData(section, orientation, role);

}

void TableModel::setData(const QVector<QStringList> &data)

{

    m_data = data;

}

TableView的实现，和model关联

#ifndef TABLEVIEW_H

#define TABLEVIEW_H

#include <QTableView>

#include "tablemodel.h"

#include "buttondelegate.h"

class TableView : public QTableView

{

    Q_OBJECT

public:

    explicit TableView(QWidget *parent = );

    TableModel* tableModel() {return m_model;}

    ~TableView();

signals:

public slots:

private:

    void iniData();

private:

    TableModel *m_model;

    ButtonDelegate *m_buttonDelegate;

};

#endif // TABLEVIEW_H
#include "tableview.h"

#include "tablemodel.h"

#include "buttondelegate.h"

TableView::TableView(QWidget *parent) :

    QTableView(parent)

{

    iniData();

}

TableView::~TableView()

{

    delete m_model;

}

void TableView::iniData()

{

    m_model = new TableModel();

    this->setModel(m_model);

    QStringList headers;

    headers << "Id" << "Progress";

    m_model->setHorizontalHeader(headers);

    QVector<QStringList> data;

    data.append(QStringList() << "" << "");

    data.append(QStringList() << "" << "");

    data.append(QStringList() << "" << "");

    data.append(QStringList() << "" << "");

    data.append(QStringList() << "" << "");

    m_model->setData(data);

    m_buttonDelegate = new ButtonDelegate(this);

    this->setItemDelegateForColumn(, m_buttonDelegate);

    emit m_model->layoutChanged();

    this->setColumnWidth(, );

}

这就完成了

我们看一下调用

    this->resize(, );

    TableView *tv = new TableView(this);

    QVBoxLayout* layout = new QVBoxLayout();

    layout->addWidget(tv);

    this->setLayout(layout);
