Avoiding QVariant::fromValue around your Own Types

In my code I have a lot of custom classes I use with model/view, including Money, PercentageValue, TimeValue just to name a few. For years I've written code like this in my data methods of QAbstractItemModel subclasses: return QVariant::fromValue(cost); // cost is an instance of the class Money In this short video you will learn a very simple trick to avoid this. The example code showcased in this video is available here: https://github.com/KDAB/kdabtv/tree/m... and https://github.com/KDAB/kdabtv/tree/m... All Qt Widgets and more videos:    • Qt Widgets and more   About the host: The video is presented by Jesper Pedersen, who started with Qt back when Qt was widgets only and the version was 1.44, which gives him 21 years of experience with Qt. Since 2000 he has taught almost 100 Qt classes, ranging from Qt Widgets to QML. Heck, Jesper even taught a few classes on QTopia Core — Trolltech's initial attempt at creating a phone stack. Today Jesper holds a fancy business title, but that doesn't prevent him from coding both in his job and in his spare time.
