Draw grid in QListView

[woodtluk]

Hi there

I'd like to draw lines between items in my list.

I try to do it in my delegate (derived from QStyledItemDelegate):

void MembersListDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const {
  if(!index.isValid())
    return;
 
  painter->save();
  painter->setRenderHint(QPainter::Antialiasing);
 
  QStyleOptionViewItemV4 opt = option;
  QStyledItemDelegate::initStyleOption(&opt, index);
 
  // ...
 
  // seperation lines
  QPen linePen(Qt::gray);
  painter->setPen(linePen);
  painter->drawLine(0, opt.rect.height(), opt.rect.width(), opt.rect.height());
 
  painter->restore();
}

void MembersListDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const {
  if(!index.isValid())
    return;

  painter->save();
  painter->setRenderHint(QPainter::Antialiasing);

  QStyleOptionViewItemV4 opt = option;
  QStyledItemDelegate::initStyleOption(&opt, index);

  // ...
  
  // seperation lines
  QPen linePen(Qt::gray);
  painter->setPen(linePen);
  painter->drawLine(0, opt.rect.height(), opt.rect.width(), opt.rect.height());

  painter->restore();
}

To copy to clipboard, switch view to plain text mode 

If I do so the line is only painted under the first item. The paint method should be called for each index and paint the line on bottom of the item.

Isn't there a ready made function for the lines between items like in QTableView::setShowGrid(bool show)?

Thaks!
