Treeview with grid lines

[phamtv]

I have a custom QSortFilterProxyModel with its source model set to the QFileSystemModel displayed via a QTreeView. Is it possible for the QTreeView to show gridlines vertically and horizontally? If so, can you provide an example. Thanks!

Hi
You can create a delegate for example :-

.h

@class TreeViewDelegate : public QStyledItemDelegate
{
Q_OBJECT
public:
explicit TreeViewDelegate(QObject *parent = 0);
void paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const;

};@

.cpp

@TreeViewDelegate::TreeViewDelegate(QObject *parent) :
QStyledItemDelegate(parent)
{

}

void TreeViewDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
QStyledItemDelegate::paint(painter,option,index);

QPen pen;
pen.setWidth(1);
painter->setPen(pen);
painter->drawRect(option.rect);

}@

then you can set the the delegate to the treeView

@ui->treeView->setItemDelagate(treeDelegate);@
