Qt Drag and Drop QListView removing the item on which it is released

Question

I working on a small QlistView which is Sortable.

    iListView = new QListView(this);
    //Creating a standard item model
    iStandardModel = new QStandardItemModel(this);

    //First item
    QStandardItem* item1 = new QStandardItem(QIcon(":/cover-story-album-art.jpg"),"First Item");
    //Second item
    QStandardItem* item2 = new QStandardItem(QIcon(":/cover-story-album-art.jpg"),"Second item");
    //third item 
    QStandardItem* item3 = new QStandardItem(QIcon(":/cover-story-album-art.jpg"),"Third![enter image description here][1] item");

    //Appending the items into model
    iStandardModel->appendRow(item1);
    iStandardModel->appendRow(item2);
    iStandardModel->appendRow(item3);

    //Setting the icon size
    iListView->setIconSize(QSize(40,30));

    //Setting the model
    iListView->setModel(iStandardModel);

    //Setting listview geometry
    iListView->setGeometry(QRect(0,0,240,320));
    iListView->setDragEnabled(true);
    iListView->setAcceptDrops(true);
    iListView->setDragDropMode(QAbstractItemView::InternalMove);

Well the Drag and Drop works but there is a issuse if i drop the item on the any other item replaced other than the end of the list.The "dragged" item replaces the "released up on" item.

Answer 1

That is because by default QStandardItem has Qt::ItemIsDropEnabled flag set. Just remove it by using QStandardItem::setFlags() function. Add following lines:

item1->setFlags(item1->flags() ^ (Qt::ItemIsDropEnabled));
item2->setFlags(item2->flags() ^ (Qt::ItemIsDropEnabled));
item3->setFlags(item3->flags() ^ (Qt::ItemIsDropEnabled));

iListView->showDropIndicator(); // For convenience..
