What is QAbstractItemDelegate?What is QItemDelegate?
Tino: Please drop the latter two ones. Lets try to concentrate on QML as much as possible not to confuse the students.
Tino: Attached properties. This is very important. How to use the attached properties, provided by views to delegates? They are visible to the root of the delegate only, so this is also important thing to mention. There could be trivial examples, such as currentItem but also Path attributes in the path view provides visually nice examples.
K: Attached properties are ListView.delayRemove, ListView.isCurrentItem, ListView.view and ListView.section stuff
