How to copy local file to QClipboard (in Gnome)?

QClipboard offers several ways to copy stuff into the clipboard. There are high level functions for standard desktop (text, pixmaps, etc), but I could not figure out how to implement the standard copy file operation. Google did not help.

Okay I found the solution to my problem. The problem is that gnome (working on linux) does its own thing. The file(s) are not stored in the text/uri-list format like N1ghtLight mentioned, but uses the special x-special/gnome-copied-files format. The following code did it:

//  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 path of file
newMimeData->setText(_file->absolutePath());

// Copy file
newMimeData->setUrls({QUrl::fromLocalFile(_file->absolutePath())});

// Copy file (gnome)
QByteArray gnomeFormat = QByteArray("copy\n").append(QUrl::fromLocalFile(_file->absolutePath()).toEncoded());
newMimeData->setData("x-special/gnome-copied-files", gnomeFormat);

// Set the mimedata
cb->setMimeData(newMimeData);

Just put appropriate mime type and URL of the local file into clipboard. Docs reference.

QMimeData* mimeData = new QMimeData();
mimeData->setData("text/uri-list", "file:///C:/fileToCopy.txt");
clipboard->setMimeData(mimeData);

You can use static method QUrl::fromLocalFile to get QUrl instance to be used in mimeData->setData :

mimeData->setData("text/uri-list", QUrl::fromLocalFile("C:/fileToCopy.txt"));
