/// **Notice these docs are heavy WIP and not very relevent yet**
///
/// When a widget [accepts drop events](QWidget::setAcceptDrops())
/// , it will
/// receive this event if it has accepted the most recent QDragEnterEvent or
/// QDragMoveEvent sent to it.
///
/// The drop event contains a proposed action, available from proposedAction(), for
/// the widget to either accept or ignore. If the action can be handled by the
/// widget, you should call the acceptProposedAction() function. Since the
/// proposed action can be a combination of [Qt::DropAction](Qt::DropAction)
/// values, it may be
/// useful to either select one of these values as a default action or ask
/// the user to select their preferred action.
///
/// If the proposed drop action is not suitable, perhaps because your custom
/// widget does not support that action, you can replace it with any of the
/// [possible drop actions](possibleActions())
/// by calling setDropAction()
/// with your preferred action. If you set a value that is not present in the
/// bitwise OR combination of values returned by possibleActions(), the default
/// copy action will be used. Once a replacement drop action has been set, call
/// accept() instead of acceptProposedAction() to complete the drop operation.
///
/// The mimeData() function provides the data dropped on the widget in a QMimeData
/// object. This contains information about the MIME type of the data in addition to
/// the data itself.
