getting the icon of a dropped file

phirestalker

I am using qt5 and I have a qlistwidget that accepts drops. The drops work as I expect, now I would like to have the file or folder icon next to the path in the qlistwidgetitem. I see that it does accept an icon, I need to know how to get the icons. From looking through the autocomplete it looks like it is only a list of urls. What can I do to get the icons for the files?

Hi and welcome to devnet,

QFileIconProvider might be what you are looking for.

Hope it helps

ok I found out how to get the icon, but I was under the impression that giving an icon in the constructor of a new qlistwidgetitem would make it display the icon next to the text? Is there some special way to make the icon appear?

here is the relevant code
void myQListWidget::dropEvent(QDropEvent *event)
{
qDebug() << "dropEvent";

if (event->mimeData()->hasUrls())
 {
     QList<QUrl> urls = event->mimeData()->urls();

         QUrl url;
         foreach (url,urls)
         {
             QIcon icon(url.toLocalFile());
             this->addItem(new QListWidgetItem( icon, url.toLocalFile()));
         }
     event->acceptProposedAction();

 }
 QListWidget::dropEvent(event);

}

Did you check that the Icon is valid ?

ya I was doing it wrong. Thanks I got it working, here is the code now

void myQListWidget::dropEvent(QDropEvent *event)
{
    qDebug() << "dropEvent";

    if (event->mimeData()->hasUrls())
     {
         QList<QUrl> urls = event->mimeData()->urls();

             QUrl url;
             foreach (url,urls)
             {
                 QFileInfo file(url.toLocalFile());
                 QFileIconProvider iconProvider;
                 QIcon icon(iconProvider.icon(file));
                 this->addItem(new QListWidgetItem( icon, url.toLocalFile()));
             }
         event->acceptProposedAction();

     }
     QListWidget::dropEvent(event);
}
