Details

    • Bug
    • Resolution: Done
    • P1: Critical

    Description

      The basis drag / drop functionality doesn't work anymore. The following example works in Qt 5.3.2 but not in Qt 5.4.0:

      void ListView::mouseMoveEvent(QMouseEvent* event)
{
    TRACE;
    if (!(event->buttons() & Qt::LeftButton)) {
        return;
    }
    if ((event->pos() - mMousePressPosition).manhattanLength() < QApplication::startDragDistance()) {
        return;
    }
    QDrag* drag = new QDrag(this);
    QMimeData* mimeData = new QMimeData;

    mimeData->setText(QString::fromLatin1("ABC"));
    mimeData->setUrls(QList<QUrl>() << QUrl::fromLocalFile("./test.cc"));

    drag->setMimeData(mimeData);

    qDebug() << Q_FUNC_INFO << mimeData->text();
    qDebug() << Q_FUNC_INFO << mimeData->urls();

    Qt::DropAction dropAction = drag->exec(Qt::CopyAction | Qt::MoveAction, Qt::CopyAction);

    qDebug() << Q_FUNC_INFO << "drop:" << dropAction;
}
