QIconDragEvent class indicates that a main icon drag has begun.
Icon drag events are sent to widgets when the main icon of a window has been dragged away. On macOS, this happens when the proxy icon of a window is dragged off the title bar.
It is normal to begin using drag and drop in response to this event.
