In this video, you will learn how to let the user drop files onto a Qt widget. The users of your application will appreciate being able to open a file by dragging it from a file manager (for instance), and dropping it onto your application.

QWidget makes this quite easy; you only have one method to call and two virtual methods to reimplement.

The example code showcased in this video is available here
