How to get called dropEvent() ?

[Yunuscinar41]

I found a toDoList project about drag&drop. And I wonder Can I get the item that dragging or dropped. I'm reading the documentation for 2 days. I implement the methods.

protected:
    void dragEnterEvent( QDragEnterEvent *anEvent ) override;
    void dragMoveEvent( QDragMoveEvent *anEvent ) override;
    void dragLeaveEvent( QDragLeaveEvent *anEvent ) override;
    void dropEvent( QDropEvent *anEvent ) override;

There are 2 listviews and toolbar. I add add and remove to the toolbar.
I can drag or drop but, I can't get text of the the items dragging. This is the main code.
And I really wonder, we override the methods right. But we do not connect the methods to something. How does the method works ?

todolist::todolist(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::todolist)

        pWidget->setLayout(pMainLayout);

        QLabel* pwTitle = new QLabel("To Do List", this);
