Qt按住Ctrl将软件元素拖到文件资源管理器中，但文件资源管理器不接受它们

#include <QApplication>

        }
    }

    void dropEvent(QDropEvent *event) override {
        const QMimeData *mimeData = event->mimeData();
        if (mimeData->hasUrls()) {
            QList<QUrl> urlList = mimeData->urls();
            if (!urlList.isEmpty()) {

                // 处理文件路径
                qDebug() << "Dropped file:" << fileName;
            }

    DragWidget widget;

    widget.show();
