Found it very easy to convert a {{DocLink|QTextDocument}} to PDF in Qt, and useful in scenarios like creating reports etc.


For example, consider the following snippet:
Below is a minimal example of how to print a {{DocLink|QTextDocument}} to PDF:


<code lang="cpp">
<code lang="cpp">
QString fileName = QFileDialog::getSaveFileName(this, tr("Save File"), "untitled", tr("PDF Document (....pdf)"));
#include <QtWidgets>
QPrinter printer;
#ifndef QT_NO_PRINTER
printer.setOutputFormat(QPrinter::PdfFormat);
#include <QPrinter>
printer.setOutputFileName(fileName);
#endif
QTextDocument doc;
 
doc->print(&printer);
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QString fileName = QFileDialog::getSaveFileName((QWidget* )0, "Export PDF", QString(), "*.pdf");
    if (QFileInfo(fileName).suffix().isEmpty()) { fileName.append(".pdf"); }
 
    QPrinter printer(QPrinter::PrinterResolution);
    printer.setOutputFormat(QPrinter::PdfFormat);
    printer.setPaperSize(QPrinter::A4);
    printer.setOutputFileName(fileName);
 
    QTextDocument doc;
    doc.setHtml("<h1>Hello, World!</h1>\n<p>Lorem ipsum dolor sit amet, consectitur adipisci elit.</p>");
    doc.setPageSize(printer.pageRect().size()); // This is necessary if you want to hide the page number
    doc.print(&printer);
}
