QHeaderView 禁用某些列排序和添加QCheckBox控件

QHeaderView禁用某些列的排序,则只需要重载mousePressEvent mouseReleaseEvent两个函数,在函数体内判断当前点击列是否为需要禁用的列,如果是则设置点击无效setSectionsClickable(false);  再调用QHeaderView::mousePressEvent(event);/QHeaderView::mouseReleaseEvent(event); 然后再setSectionsClickable(true);

代码如下:

void HanderView::mousePressEvent(QMouseEvent* event)
{
 const int index = logicalIndexAt(event->pos());
 if (0 <= m_forbinSortList.indexOf(index))
 {
  setSectionsClickable(false);
 }
 QHeaderView::mousePressEvent(event);
 if (!sectionsClickable())
 {
  setSectionsClickable(true);
 }
}

void HanderView::mouseReleaseEvent(QMouseEvent* event)
{
 const int index = logicalIndexAt(event->pos());
 if (0 <= m_forbinSortList.indexOf(index))
 {
  setSectionsClickable(false);
 }
 QHeaderView::mouseReleaseEvent(event);
 if (!sectionsClickable())
 {
  setSectionsClickable(true);
 }
}


添加QCheckBox:

HanderView::HanderView(Qt::Orientation orientation, QWidget *parent)
 : QHeaderView(orientation, parent)
{
 m_pCheckBox = new QCheckBox(this);
 m_pCheckBox->setFixedSize(qRound(1.3 * m_pCheckBox->sizeHint().height()),
  m_pCheckBox->sizeHint().height());
 m_pCheckBox->setFocusPolicy(Qt::NoFocus);
}


void HanderView::paintSection(QPainter* painter, const QRect& rect, int logicalIndex) const
{
 if (0 == logicalIndex)
 {
  int iYOffset = m_pCheckBox->height() < rect.height()
   ? (rect.height() - m_pCheckBox->height()) /2 : 0;
  QRect rectCheckBox(rect.x() + 3, rect.y() + iYOffset,
   m_pCheckBox->width(), m_pCheckBox->height());
  m_pCheckBox->setGeometry(rectCheckBox);
 }

 QHeaderView::paintSection(painter, rect, logicalIndex);
}


 header()->setStyleSheet("\
       QHeaderView::section {\
       background-color:#f2f2f2;\
       padding-left: 1px;\
       border-left:  0;\
       border-right: 0;\
       border-top: 1px solid #cdd4df;\
       border-bottom: 0;\
       height: 25px;}\
       QHeaderView::section:first{\
       padding: 0px 0px 0px 22px;}\
       QHeaderView::up-arrow{\
       subcontrol-origin: padding;\
       subcontrol-position: right;\
       width: 15px; padding-right: 20px;}\
       QHeaderView::down-arrow{\
       subcontrol-origin: padding;\
       subcontrol-position: right;\
       width: 15px; padding-right: 20px;\
       }");
