One of the most important inspectors available in GammaRay is the Qt Quick Scenes inspector. It allows you to visualize the object tree of a QML scene, the visual positioning of the items, and much more. In this video, we are going to show you how to use GammaRay to solve a practical problem in Qt Quick: why is my element not visible?

There are many possible reasons, and the non-imperative nature of QML makes it harder than usual to try and debug such a problem. However, GammaRay makes it possible to fix the mistake in a matter of seconds.
