Edit QTextDocument for printing

[ericV]

As I am working on a custom Code Editor I have run into a new problem.

I want to be able to print the QTextDocument, but prepend the line number in each block.

Printing the document as is is no problem, thanks to

QTextDocument::print()

QTextDocument::print()

To copy to clipboard, switch view to plain text mode 

I was thinking along the lines of cloning the original document and editing each block... but i cant find any way to insert additional text into it.

and i don't want to get the plain text out, because it would destroy the formatting created by my highlighter... ( This would also be the reason why I'm looking to do this directly in the document)

Does anyone have an idea?

UPDATE:
Im going to try using a QTextCursor on the document.... i hope this works.

Last Update:

I got it to work (not very elegant though)

void EditorWindow::printDocument(QPrinter &printer)
{
    QTextDocument *document = codeEditor->getDocument();
    QTextCursor *documentCursor = new QTextCursor(document);
 
    QTextCharFormat numberFormat;
    numberFormat.setForeground(QBrush(QColor("blue")));
    numberFormat.setFontItalic(true);
    documentCursor->beginEditBlock();
    do{
        documentCursor->insertText("<"+QString::number(documentCursor->blockNumber()+1,10)
                                   +">\t",numberFormat
                                   );
 
    }while(documentCursor->movePosition(QTextCursor::NextBlock));
 
    documentCursor->endEditBlock();
    document->print(&printer);
    document->undo();
 
}

void EditorWindow::printDocument(QPrinter &printer)
{
    QTextDocument *document = codeEditor->getDocument();
    QTextCursor *documentCursor = new QTextCursor(document);

    QTextCharFormat numberFormat;
    numberFormat.setForeground(QBrush(QColor("blue")));
    numberFormat.setFontItalic(true);
    documentCursor->beginEditBlock();
    do{
        documentCursor->insertText("<"+QString::number(documentCursor->blockNumber()+1,10)
                                   +">\t",numberFormat
                                   );

    }while(documentCursor->movePosition(QTextCursor::NextBlock));

    documentCursor->endEditBlock();
    document->print(&printer);
    document->undo();

}
