问题 I'm working on a simple project to try and learn QT 5.7, QML, and C++. I want to create a simple interface that has a list of items that I can add and remove items from using a couple of buttons. I've been reading a bunch of different guides online trying to piece together something but I keep getting stuck. I've tried using QQmlListProperty<T> and QAbstractListModel but I have questions about both approaches: For my project is QQmlListProperty<T> the right thing to use or I should use

Add 32-bit versions of Qt 5.7 on a 64-bit machine
