How can I do page numbering?

[AlexeyGolubev92]

Help me.
I want to number the pages in the footer.
To create a document, I use QTextEdit, QTextCursor, QTextDocument, QTextDocumentWriter.
Using QTextDocumentWriter, I create a report.odt document. I use LibreOffice to open report.odt.
code:

sourceTextEdit = new QTextEdit();
QString lorem="Lorem ipsum tellus, eros ipsum lectus justo malesuada massa enim"
          " urna ipsum adipiscing in elementum porttitor arcu quisque "
          "curabitur justo sit eros orci. Rutrum, sit nec cursus et malesuada"
          " diam odio proin at tempus non.";
QTextCursor cursor = sourceTextEdit->textCursor();
cursor.insertText(lorem);
textDocument = sourceTextEdit->document();
QTextDocumentWriter writer;
writer.setFormat("odf");
writer.setFileName("report.odt");
writer.write(textDocument);

How can I do page numbering in report.odt?
