QListWidget Dragging Problem after scrolling down the list



  • I am creating A Sortable List in Qt. The Code works perfectly well for Downward Scroll but when i having some issues getting the draggable item after i scroll the list down. I have added some test case screenshot for better understanding

    Well this is the test case code

    @ ui->listWidget->addItem("SongOne");
    ui->listWidget->addItem("SongTwo");
    ui->listWidget->addItem("SongThree");
    ui->listWidget->addItem("SongFour");
    ui->listWidget->addItem("SongFive");
    ui->listWidget->setDragDropMode(QAbstractItemView::InternalMove);
    ui->listWidget->setDragEnabled(true);
    ui->listWidget->setAcceptDrops(true);
    ui->listWidget->setDropIndicatorShown(true);
    ui->listWidget->viewport()->setAcceptDrops(true);
    ui->listWidget->setSelectionMode(QAbstractItemView::SingleSelection);@

    Thankz for taking the time in reading my post. Do help me if you have any hint on what i am missing out.I think i am missing setting some property. In the main Program(not the test code), i tried rewriting the dragMoveEvent and few more method, but no use.



  • @#include <QtGui>

    int main(int argc, char **argv) {
    QApplication app(argc, argv);
    QListWidget *listWidget = new QListWidget;
    for(int i=0;i<100;++i){
    listWidget->addItem("SongOne");
    listWidget->addItem("SongTwo");
    listWidget->addItem("SongThree");
    listWidget->addItem("SongFour");
    listWidget->addItem("SongFive");
    }
    listWidget->setDragDropMode(QAbstractItemView::InternalMove);
    listWidget->setDragEnabled(true);
    listWidget->setAcceptDrops(true);
    listWidget->setDropIndicatorShown(true);
    listWidget->viewport()->setAcceptDrops(true);
    listWidget->setSelectionMode(QAbstractItemView::SingleSelection);
    listWidget->show();
    app.exec();
    delete listWidget;
    return 0;
    }@
