 QByteArray ba;
        // Create a data stream that operates on the binary data
        QDataStream ds(&ba, QIODevice::WriteOnly);
        // Add each item's text for col 0 to the stream
        QMimeData *md = new QMimeData;

Use QAbstractItemView::setDragDropMode and QAbstractItemView::setDragEnabled to enable drag & drop on your QTreeWidget.

Use QStandardItem::setDropEnabled to allow/disallow drops on a specific item.

Hi All

I enbled the drag and drop for QTreeWidget ...

ui->treeWidget->dragDropOverwriteMode();
ui->treeWidget->setDragEnabled(true);
ui->treeWidget->setDragDropMode(QAbstractItemView ::InternalMove);

toplevelitems only accept the drops... I don't know how do implement..and if dropped itmes already is in toplevel childs ,it won't accept...

Some has replied using QStandardItem..

I created object for QStandardItem and i assined the the toplevelitem for object.. But it is giving errors.

Any suggestions are most Welcome..

Advance Thanks
