How to do action when QStringListModel changed?

Basically, I have 2 listviews and when I drag&drop one listview to another one,I want to execute a sql query.

I tried to override dropEvent but it does not getting called. However the drop action happening.(I go through the model data with for loop and I can print the items in the model)

enter image description here

Why the dropEvent not called when drop happens ?

protected:
    void mousePressEvent(QMouseEvent *event)override;
    void mouseMoveEvent(QMouseEvent *event)override;
    void dragEnterEvent(QDragEnterEvent *event)override;
    void dragMoveEvent(QDragMoveEvent *event)override;
    void dragLeaveEvent(QDragLeaveEvent *event)override;
    void dropEvent(QDropEvent *event)override;

void InformationMusteriDialog::dropEvent(QDropEvent *event) {
    QMessageBox::information(this,"x","xss");
    event->acceptProposedAction();
}
Solution

  • I solve the problem if anyone curious about this problem.

    I thought I can connect QStringListModel with SIGNAL and SLOT.

    connect(ui->listViewMusteri->model(),&QAbstractItemModel::dataChanged,this, &InformationMusteriDialog::listViewMusteriChanged);      
connect(ui->listViewToplam->model(),&QAbstractItemModel::dataChanged,this, &InformationMusteriDialog::listViewToplamChanged);

    When model's data is changed, you can do something.

    (btw I'm keep searching about DnD methods.)
