How can i show rtf file in QTextEdit in qt?
Can I use QClipboard to convert the text to html and paste it in the QTextEdit like the following code? Thank you very much.

QString filename="/home/clement/test.rtf";
 
    QFile file(filename);
    if (file.open(QIODevice::ReadOnly | QIODevice::Text)) {
        ui->textEdit->setPlainText(file.readAll());
    }
    file.close();
 
    QTextDocument *document = ui->textEdit->document();
 
    QClipboard *board = QApplication::clipboard();
    QMimeData *mimeData = new QMimeData();
    mimeData->setText(document->toPlainText());
    board->setMimeData(mimeData, QClipboard::Clipboard);
 
    QString str = board->text();
    QMessageBox::information(NULL, tr("剪貼簿內容"), str);

QString filename="/home/clement/test.rtf";

    QFile file(filename);
    if (file.open(QIODevice::ReadOnly | QIODevice::Text)) {
        ui->textEdit->setPlainText(file.readAll());
    }
    file.close();

    QTextDocument *document = ui->textEdit->document();

    QClipboard *board = QApplication::clipboard();
    QMimeData *mimeData = new QMimeData();
    mimeData->setText(document->toPlainText());
    board->setMimeData(mimeData, QClipboard::Clipboard);

    QString str = board->text();
    QMessageBox::information(NULL, tr("剪貼簿內容"), str);

To copy to clipboard, switch view to plain text mode
