Answer 1

QTreeWidgetItems have the property childIndicatorPolicy. The allowed values are:

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

You want the first one.

theItem.setChildIndicatorPolicy(QTreeWidgetItem.ShowIndicator)
