QTextDocumentWriter removes carriage return translation to tables when creating a document

[AlexeyGolubev92]

When I create a document using QTextDocumentWriter in the "odf" format, line wrapping in the table does not work. When I create an "html" document, line wrapping in the table works. The "odf" format is required for older versions of the open office. In older versions, the office version "HTML" does not open. How to make a row transfer to a table in "odf" format? Attached the test code:

#include <QString>
#include <QTextStream>
#include <QTextDocument>
#include <QTextDocumentWriter>
#include <QTextCursor>
#include <QTextBlock>
#include <QDate>
#include <QTextTableCell>

void createsOdfWithTable(){
QTextDocument *doc = new QTextDocument;
doc->setDocumentMargin(10);

QTextCursor cursor(doc);
cursor.movePosition(QTextCursor::Start);

QTextCharFormat textFormat;
textFormat.setFontPointSize(10);
QTextCharFormat boldFormat;
boldFormat.setFontWeight(QFont::Bold);

//HEADERS
QTextCharFormat header1Format = boldFormat;
header1Format.setFontPointSize(12);
header1Format.setFontUnderline(true);
header1Format.setForeground(QBrush(QColor("#0000FF")));

QTextCharFormat header2Format = header1Format;
header2Format.setFontPointSize(14);
QTextCharFormat header3Format = header1Format;
header3Format.setFontPointSize(16);

QTextCharFormat titleFormat = boldFormat;
titleFormat.setFontPointSize(20);
header1Format.setForeground(QBrush(QColor("#0000FF")));

QTextBlockFormat blockFormat = cursor.block().blockFormat();
QTextBlockFormat titleBlockFormat = cursor.block().blockFormat();
titleBlockFormat.setAlignment(Qt::AlignHCenter);

QTextCharFormat alternateCellFormat = textFormat;
alternateCellFormat.setBackground(QBrush(QColor("#D1EBFF")));

QTextTableFormat tableFormat;
tableFormat.setBorder(1);
tableFormat.setBorderStyle(QTextFrameFormat::BorderStyle_Solid);
tableFormat.setCellPadding(2);
tableFormat.setCellSpacing(0);
tableFormat.setWidth(QTextLength(QTextLength::PercentageLength, 80));
tableFormat.setAlignment(Qt::AlignLeft);

//Title of the document
cursor.insertBlock();
cursor.setBlockCharFormat(titleFormat);
cursor.setBlockFormat(titleBlockFormat);
cursor.insertText(QObject::tr("My Great Document !"));
cursor.insertBlock(); //new line
cursor.insertBlock();
cursor.insertBlock();

cursor.setBlockFormat(blockFormat);
cursor.insertText(QObject::tr("Header 1"), header1Format);
cursor.insertBlock();

cursor.setCharFormat(textFormat);

cursor.insertText("Author:\tMe");
cursor.insertBlock();
cursor.insertText("Version:\tMe");
cursor.insertBlock();
cursor.insertText("Date:\t" + QDate::currentDate().toString("dd.MM.yyyy"));
cursor.insertBlock();

cursor.insertText(QObject::tr("Header 2"), header2Format);
cursor.insertBlock();
cursor.insertText(QObject::tr("Header 3"), header3Format);
cursor.insertBlock();

//Insert table with nb row = 10, column = 2
QTextTable *table = cursor.insertTable(10+1, 2, tableFormat);
QTextTableCell headerCell = table->cellAt(0, 0);
QTextCursor headerCellCursor = headerCell.firstCursorPosition();
headerCellCursor.insertText(QObject::tr("Name"), boldFormat);
headerCell = table->cellAt(0, 1);
headerCellCursor = headerCell.firstCursorPosition();
headerCellCursor.insertText(QObject::tr("Value"), boldFormat);

for(int i = 0; i < 10; i++){
    QTextCharFormat cellFormat = i % 2 == 0 ? textFormat : alternateCellFormat;
    QTextTableCell cell = table->cellAt(i + 1, 0);
    cell.setFormat(cellFormat);
    QTextCursor cellCursor = cell.firstCursorPosition();
    cellCursor.insertText("Row \n" + QString::number(i));

    cell = table->cellAt(i + 1, 1);
    cell.setFormat(cellFormat);
    cellCursor = cell.firstCursorPosition();
    cellCursor.insertText(QString::number(i));
}

cursor.movePosition(QTextCursor::End);


QTextDocumentWriter writer("test3.odt");
writer.setFormat("odf");
writer.write(doc);
QTextDocumentWriter writer2("test4.odt");
writer2.setFormat("html");
writer2.write(doc);

delete doc;
}


int main(int argc, char *argv[])
{
 QApplication a(argc, argv);
 createsOdfWithTable();
 return a.exec();
}

Hi,

You should add which version of Qt you are using as well as which version of LibreOffice.

@AlexeyGolubev92 said in QTextDocumentWriter removes carriage return translation to tables when creating a document:

QTextCursor cellCursor = cell.firstCursorPosition();
cellCursor.insertText("Row \n" + QString::number(i));

Perhaps this (like your earlier code that starts a new paragraph):

    QTextCursor cellCursor = cell.firstCursorPosition();
    cellCursor.insertText("Row");
    cellCursort.insertBlock();
    cellCursor.insertText( QString::number(i));

@ChrisW67 Experienced. The code doesn't work. It does not transfer the string.
