Multiple file insert in QTreewidget using Drag and Drop events

Question

I am working in Qt4.7 on MAC OSx. I want to insert files in QTreewidget using the Drag and Drop events. I want to add multiple files at a time. I am using this:

void MainWindow::dragEnterEvent(QDragEnterEvent * e)
{
    if(e->mimeData()->hasUrls())
    {
        e->acceptProposedAction();
    }

}
void MainWindow::dropEvent(QDropEvent * e)
{
    QTreeWidgetItem *Items = new QTreeWidgetItem(ui->treeWidget);
    foreach(const QUrl &url,e->mimeData()->urls())
    {
        const QString &filename = url.toLocalFile();
        qDebug() << "Dropped file:" << filename;
        Items->setText(0,filename);
    }
}

Using this, I am able to insert only one file at a time. Is there anyone who can help me out in this issue ? Your help will really appreciate.

Thanks, Ashish.

The problem is that you create only one tree view item. However you need one per each Url you passed with the mime data:

void MainWindow::dropEvent(QDropEvent *e)
{
    foreach(const QUrl &url, e->mimeData()->urls()) {
        QString filename = url.toLocalFile();
        qDebug() << "Dropped file:" << filename;
        QTreeWidgetItem *item = new QTreeWidgetItem(ui->treeWidget);
        item->setText(0, filename);
    }
}
