Qt 复制文件到剪贴板

复制图片的内容到剪贴板：

        QImage img(path);        Q_ASSERT(!img.isNull());        cb->setImage(img, QClipboard::Clipboard);

复制大量文件的路径：

void copyFilesToClipboard(const QStringList &paths){    //  Get clipboard    QClipboard *cb = QApplication::clipboard();    // Ownership of the new data is transferred to the clipboard.    QMimeData* newMimeData = new QMimeData();    // Copy old mimedata    const QMimeData* oldMimeData = cb->mimeData();    for ( const QString &f : oldMimeData->formats())        newMimeData->setData(f, oldMimeData->data(f));    // Copy file (gnome)    QByteArray gnomeFormat = QByteArray("copy\n");    QString text;    QList<QUrl> dataUrls;    for (QString path : paths) {        if (!path.isEmpty())            text += path + "\n";        dataUrls << QUrl(QFileInfo(path).absoluteFilePath());        gnomeFormat.append(QUrl::fromLocalFile(path).toEncoded()).append("\n");    }  //setText  need to be called, or you can't clip the context to clipboard.    newMimeData->setText(text);   newMimeData->setUrls(dataUrls);    gnomeFormat.remove(gnomeFormat.length() - 1, 1);    newMimeData->setData("x-special/gnome-copied-files", gnomeFormat);    // Set the mimedata    cb->setMimeData(newMimeData);}
