Qt

The Qt module consolidates the contents of most of the other modules into a single module. (Excluded are the Qt3D, Chart, Data Visualization and Purchasing modules). This has the advantage that you don’t have to worry about which underlying module contains a particular class. It has the disadvantage that it loads the whole of the Qt framework, thereby significantly increasing the memory footprint of an application. Whether you use this consolidated module, or the individual component modules is down to personal taste.
