QtreeWidget drag and drop

[addu]

Hi all


Please parden me ,if my question is silly..

How do implement the drag and drop for inside QTreewidget.. top toplevelitems only accept drops and if it have same item already it has to neglect it.. i tried with

void MainWindow::dragEnterEvent(QDragEnterEvent *event)
{
if (event->source() == this) {
            event->setDropAction(Qt::MoveAction);
            event->accept();
}
void MainWindow::dragEnterEvent(QDragEnterEvent *event)
{
    event->accept();
 
void MainWindow::dropEvent(QDropEvent *event)
{
 if(ui->treeWidget->topLevelItem(1))
    {
 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;
        // Set the data associated with the mime type foo/bar to ba
        md->setData("foo/bar", ba);
 
 }
}

void MainWindow::dragEnterEvent(QDragEnterEvent *event)
{
if (event->source() == this) {
            event->setDropAction(Qt::MoveAction);
            event->accept();
}
void MainWindow::dragEnterEvent(QDragEnterEvent *event)
{
    event->accept();

void MainWindow::dropEvent(QDropEvent *event)
{
 if(ui->treeWidget->topLevelItem(1))
    {
 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;
        // Set the data associated with the mime type foo/bar to ba
        md->setData("foo/bar", ba);

 }
}
