QClipboard *clipboard = QApplication::clipboard();
QString text = clipboard->text();

• Use the mimeData object of QClipboard to determine the content properties of the clipboard.
• Compared with QClipboard, mimeData can recognize image data, html data, and plain text data.
• Example: (1) Obtain the contents of the system clipboard:

const QClipboard *clipboard = QApplication::clipboard();
const QMimeData *mimeData = clipboard->mimeData();

if (mimeData->hasImage()) {
    /* Get clipboard image data*/
    QPixmap pixmap = qvariant_cast<QPixmap>(mimeData->imageData());
    ...
} 
else if (mimeData->hasHtml()) {
    /* Get clipboard html data*/
    QString html = mimeData->html();
    ...
} 
else if (mimeData->hasText()) {
    /* Get the clipboard plain text data*/
    QString text = mimeData->text();
    ...
} 
else {
    setText("Cannot display data");
}

  (2) Set the content of the system clipboard:

QClipboard *clipboard = QApplication::clipboard();
QMimeData mimeData;
mimeData.setImageData(QPixmap("hello.png")); //image data
// mimeData.setHtml("<h1>Heool world.</h1>"); //Html data
// mimeData.setText("Hello world."); //plain text data
clipboard->setMimeData(&mimeData);
