I was created a app ui, a file or program, represented by an icon,

I want draging a icon to github, and then the file upload to github
my drag code like this

Code:

---

QMimeData* mimeData = new QMimeData;
    QList<QUrl> urls;
    foreach (DesktopItemPointer pCheckedItem, m_checkedDesktopItems) {
        urls.append(pCheckedItem->getRawUrl());
    }
 
    mimeData->setUrls(urls);
 
    if (m_checkedDesktopItems.length() > 0){
        QPixmap dragPixmap = getCheckedPixmap();
        QDrag* pDrag = new QDrag(this);
        pDrag->setMimeData(mimeData);
        pDrag->setPixmap(dragPixmap);
        QRect borderRect = getCheckedBorderRect();
        pDrag->setHotSpot(QPoint(-borderRect.x() + QCursor::pos().x(), -borderRect.y() + QCursor::pos().y() ));
        Qt::DropAction action = pDrag->exec(Qt::MoveAction | Qt::CopyAction, Qt::CopyAction);

code on github: https://github.com/linuxdeepin/dde-d...frame.cpp#L514

but the file can't upload, I suspect that the problem is with mimedata ...

github support drag file to upload

"File uploading is now available
You can now drag and drop files into your repositories. "

What does "drag to github" mean?

Dragging into a special Github client app?
Dragging into a browser?
Dragging into a Git UI that works on a clone of a github repository?
