[Help] Remove page number, on QTextDocument's print()

[rivci]

Hi everyone

Wonder if there is a way to remove page number on QTextDocument's print(QPrinter*)

[rivci]

Finally I get my solution,

Instead of QTextDocument's print(), I use QTextDocument's drawContents().

Codes below will show the way how to do this:

QTextDocument textDocument;
printer->setPageMargins(0.925, 0.8, 0.5, 0.8, QPrinter::Inch);  //set page margin
 
QSizeF paperSize;     
paperSize.setWidth(printer->width());
paperSize.setHeight(printer->height());
textDocument.setPageSize(paperSize);
 
QPainter painter(printer);
textDocument.setHtml(contentFormula);   //contentFormula contains some html tags
 
textDocument.drawContents(&painter);

QTextDocument textDocument;
printer->setPageMargins(0.925, 0.8, 0.5, 0.8, QPrinter::Inch);  //set page margin

QSizeF paperSize;     
paperSize.setWidth(printer->width());
paperSize.setHeight(printer->height());
textDocument.setPageSize(paperSize);

QPainter painter(printer);
textDocument.setHtml(contentFormula);   //contentFormula contains some html tags

textDocument.drawContents(&painter);

To copy to clipboard, switch view to plain text mode 

hope this'll be usefull

Hello,

you can also use the print() method to print without the page number!
The key is, that the QTextDocument needs a valid pageSize.

QPrinter printer(QPrinter::ScreenResolution);
printer.setPaperSize(QPrinter::A4);
printer.setOutputFormat(QPrinter::PdfFormat);
printer.setOutputFileName( fileName );
// printer.setPageMargins(0.925, 0.8, 0.5, 0.8, QPrinter::Inch);
 
QSizeF paperSize;
paperSize.setWidth(printer.width());
paperSize.setHeight(printer.height());
document->setHtml(html);
document->setPageSize(paperSize);         // the document needs a valid PageSize
document->print(&printer);

QPrinter printer(QPrinter::ScreenResolution);
printer.setPaperSize(QPrinter::A4);
printer.setOutputFormat(QPrinter::PdfFormat);
printer.setOutputFileName( fileName );
// printer.setPageMargins(0.925, 0.8, 0.5, 0.8, QPrinter::Inch);

QSizeF paperSize;
paperSize.setWidth(printer.width());
paperSize.setHeight(printer.height());
document->setHtml(html);
document->setPageSize(paperSize);         // the document needs a valid PageSize
document->print(&printer);

To copy to clipboard, switch view to plain text mode 

When you refer the source code of print(), then you will recognize that the < QPointF pageNumberPos; > is only defined when there is no valid QTextDocument.pageSize().
In printPage() the page number will be just printed, if pageNumberPos is not null.
So just set a valid QTextDocumtent.pageSize() and you have no page numbers on your printed document.

I hope this bug will be fixed in a future release. (It's a reported bug)

good luck
