4. create .odt with headings and tables

create .odt with headings and tables


  • I need to create a .odt file that contains headings (such as heading 1 or heading 2) and tables.

    I tried something like this:

    #include <QString>
#include <QTextStream>
#include <QTextDocument>
#include <QTextDocumentWriter>

int main(void)
{
    QString strStream;
    QTextStream out(&strStream);

    QTextDocument *document = new QTextDocument();

    out << "<!DOCTYPE html>"
        << "<html>\n"
        << "<head>"
        << "<title>Test</title>"
        << "</head>"
        << "<body>"
        << "<h1>Test heading 1</h1>"
        << "</body>"
        << "</html>";
    document->setHtml(strStream);

    QTextDocumentWriter writer("test.odt");

    writer.setFormat("odf");
    writer.write(document);

    delete document;
    return 0;
}

    but the product .odt file has no heading.

    what I would like to be heading 1 doesn't have the Heading 1 style, but, in fact, it's a Default Style bold text.

    How do I force Heading 1 style?

    best regards
    Max

    This is not a problem of QTextDocumentWriter, the information about the h1 tag is lost in document->setHtml(strStream); (ref1 and ref2).

    Fixing this would imply a huge effort.

  • @VRonin Is there an alternative way to html to get an odt with heading 1 and a table, maybe even with custom styles?

    The easiest method I see is using QXmlStreamWriter + a zip library to create the file from scratch but, as you can imagine, it's far from being "easy"

    You can create you own style using QTextCharFormat and QTextBlockFormat and then creating the document using the QTextDocument API.

    Here is an example:
    You will see htmlToOdf() function is simply your code, but createsOdf() and createsOdfWithTable() creates a ODT file using custom style the the QTextDocument API. Hope it helps

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


void htmlToOdf(){
    QString strStream;
    QTextStream out(&strStream);

    QTextDocument *document = new QTextDocument();

    out << "<!DOCTYPE html>"
        << "<html>"
        << "<head>"
        << "<title>Test</title>"
        << "</head>"
        << "<body>"
        << "<h1>Test heading 1</h1>"
        << "</body>"
        << "</html>";
    document->setHtml(strStream);

    QTextDocumentWriter writer("test.odt");
    writer.setFormat("odf");
    writer.write(document);
    QTextDocumentWriter writer2("test.html");
    writer2.setFormat("html");
    writer2.write(document);

    delete document;
}

void createsOdf(){

    doc->setDocumentMargin(10);
