Introduction to Qt / QML (Part 17) - Custom Components
Welcome to the fourth module of our "Introduction to Qt / QML" series! In this module we will explore components: that is, how to reuse QML code by encapsulating it in a separate piece that we can then create as many times as needed.
In this video, we will show the basics of creating an "out-of-line" component: a component defined in a separate QML file. This is so easy it's almost magical.
The hard part comes later: how do we define a proper API for our components, so that we can use them effectively? This involves defining properties, methods, signals, slots on our components. We are going to discuss properties in this video, and the rest in the next video of this module.

About the host:
This 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.
