[Qt-interest] QTReeWidget Drag and Drop

[Sujan Dasmahapatra]

Dear Friends
I am trying to implement drag and drop for QTreeWidgetItem.I have some
toplevelitems and some of them have children items. I want to implement
hte drag and drop functionality for the toplevel items, when an item if
dragged and dropped the toplevele items and its children items all
should occupy the new place. Somekind of reordering I want to achieve.
Please give me some guidelines.
I am curreny trying to implement startDrag() but its crashing.

void Tree::startDrag(Qt::DropActions supportedActions)
{
QDrag *drag = new QDrag(this);
QMimeData *data = new QMimeData;
data->setText(currentItem()->text(0));
drag->setMimeData(data);
drag->exec(supportedActions, Qt::MoveAction);
}

Thanks in advance

 

 

Kind Regards,
