Couldn't print Arabic right

[deleted385]

Here's how it appears on UI and PDF:

looks ok on the UI BUT when I print it's terrible! Row Surah 1, Ayah 1 completely vanished in the PDF and those diacritical marks collude with previous/following rows. Here's the project in GitHub, I also have added the sample database, quran.db, for testing.

Please commit source code to GitHub as individual text files, not as a zipped file. That defeats the purpose of a version control system like Git.

Anyway, please tell us how you tried to print as PDF.

@JKSH, here's my print function:

void QueryResultView::printTable(){
    QPrinter printer;
    QPrintDialog dialog(&printer);
    if(dialog.exec() != QPrintDialog::Accepted) return;
    printer.setPageMargins(QMarginsF(72,72,72,72), QPageLayout::Point);
    printer.setResolution(fontMetrics().fontDpi());
    QTextDocument document;
    auto pageSize = printer.pageRect(QPrinter::DevicePixel).size();
    document.setPageSize(pageSize);
    QTextCursor cursor(&document);
    QTextTableFormat tableFormat;
    tableFormat.setBorder(0);
    tableFormat.setCellSpacing(0);
    tableFormat.setCellPadding(0);
    tableFormat.setHeaderRowCount(1);
    tableFormat.setWidth(QTextLength(QTextLength::PercentageLength, 100));
    int row = resultModel->rowCount() + 1;
    int column = resultModel->columnCount();
    cursor.insertTable(row, column, tableFormat);
    addHeader(cursor);
    for (int r = 1; r < row; r++) {
        for (int c = 0; c < column; c++) {
            auto index = table->model()->index(r, c);
            cursor.insertText( table->model()->data(index).toString() );
            cursor.movePosition(QTextCursor::NextCell);
        }
    }
    auto date = QDateTime::currentDateTime().toString("dd MMMM, yyyy");
    auto time = QDateTime::currentDateTime().toString("hh:mm:ss AP");
    int pageCount = document.pageCount();
    QPainter painter(&printer);
    for (int pageNo = 0; pageNo < pageCount; pageNo++) {
        if (pageNo > 0) printer.newPage();
        const QRectF currentPage(0, pageNo * pageSize.height(), pageSize.width(), pageSize.height());
        painter.save();
        painter.translate(0, -currentPage.top());
        document.drawContents(&painter, QRectF(0, currentPage.top(), pageSize.width(), pageSize.height()));
        painter.restore();
        QRectF footerRect(0, pageSize.height(), pageSize.width(), fontMetrics().height());
        painter.drawLine(footerRect.left(), footerRect.top(), footerRect.right(), footerRect.top());
        painter.drawText(footerRect, Qt::AlignVCenter | Qt::AlignLeft, "Generated on " + date + " | " + time);
        painter.drawText(footerRect, Qt::AlignVCenter | Qt::AlignRight, QString("Page: %1/%2").arg(pageNo + 1).arg(pageCount));
    }
}

When I upload a folder in github, it doesn't work!

EDIT
When the print dialog appeared, I selected Microsoft Print to PDF and clicked Print after selecting file location and providing file name.

@JKSH, to bring in the first row, I should've had r - 1 in for:

for (int r = 1; r < row; r++) {
    for (int c = 0; c < column; c++) {
        auto index = table->model()->index(r - 1, c);
        cursor.insertText( table->model()->data(index).toString() );
        cursor.movePosition(QTextCursor::NextCell);
    }
}

copy/paste error! BUT those diacritical marks still overlaps with previous/following rows and becomes unreadable.

I'm not familiar with the QTextCursor API, so I'll let someone else comment on your code.

For now, I recommend you just try to print a simple PDF with 2 lines. Keep modifying the code until you get 2 lines that don't overlap.

GitHub is not for uploading files. You should commit your code on your PC and then push it to GitHub: https://docs.github.com/en/get-started/quickstart/hello-world
