Answering on my second part of question for others.

I looked for drawing functions in QTreeView and found following:

void QTreeView::drawBranches ( QPainter * painter, const QRect & rect, const QModelIndex & index )

With this function you can draw whatever you want at the left side of each item.

And another good choice to hanlde this - use Style Sheets for QTreeView:

QTreeWidgetItems have the property childIndicatorPolicy. The allowed values are:

  • QTreeWidgetItem::ShowIndicator
  • QTreeWidgetItem::DontShowIndicator
  • QTreeWidgetItem::DontShowIndicatorWhenChildless

You want the first one.

theItem.setChildIndicatorPolicy(QTreeWidgetItem.ShowIndicator)
