Sync Width

How to synchronize QTextEdit width with QPrinter Paper width, and QTextEdit document margin with QPrinter page margin.

I not have a good method

Width like sync with this code. But I'm not sure.

//sync width
int mw=printer.paperSize(QPrinter::DevicePixel).width();
ui->textEdit->setMaximumWidth(mw);

//sync width
int mw=printer.paperSize(QPrinter::DevicePixel).width();
ui->textEdit->setMaximumWidth(mw);

To copy to clipboard, switch view to plain text mode 

And code for sync margin still not work

//sync margin
printer.setPageMargins(20, 20, 20, 20, QPrinter::DevicePixel);
ui->textEdit->document()->setDocumentMargin(20);
 
 
//I use GIMP and get 1pixel is 0.35 millimeter
qreal aa=0.35 * 20.0;
printer.setPageMargins(aa, aa, aa, aa, QPrinter::Millimeter);
ui->textEdit->document()->setDocumentMargin(20);

//sync margin
printer.setPageMargins(20, 20, 20, 20, QPrinter::DevicePixel);
ui->textEdit->document()->setDocumentMargin(20);


//I use GIMP and get 1pixel is 0.35 millimeter
qreal aa=0.35 * 20.0;
printer.setPageMargins(aa, aa, aa, aa, QPrinter::Millimeter);
ui->textEdit->document()->setDocumentMargin(20);

To copy to clipboard, switch view to plain text mode 

Sorry, with my english..

What do you mean by "sync"? The text edit is completely irrelevant. What is important is the text document it operates on. "Synchronize" the widget with the document and then print the document on the printer setup properly for the document size.
