Question

I have a QTreeWidget that items append to it dynamically, I want to set lines between them, I have first pictures and I want it to be like the second one, but I don't know how doing it? thank you in advance!

Well you can experiment with stylesheets:

treeWidget->setStyleSheet("QTreeWidget::item { border-bottom: 1px solid black;}");

But I am not sure if can get exactly the look you want. You can also subclass QStyledItemDelegate and provide your own sizeHint() and paint() implementations.
