    Hello,

    I tried to print a html file via QTextDocument.

    I use following code:

    QTextDocument *doc = new QTextDocument();
    doc->setHtml(htmlContent);
    doc->print(printer);
    

    The result is not that what i expect.
    See the attachment.

        Super.
        You should look at the doc on screen and see if same is shown.
        If yes, it means that QTextDocument and you
        do not agree how the HTML should be rendered :)

            Nope. Looks like footer is up in data or something?
            Does it also do this on screen?

              no the data is in the footer/header. it just happens if the cell data has more than one row.
              the last than splitts onto two pages

                Hi
                But it only splits to other page if page is full?
                It sounds like expected action. It will not reduce font size to
                make it fit :)

                  it splits the cell at the left ( Date ).

                  Expected result:

                  1. change font size
                  2. move last row to the next page

                    Hi, as far as I know it will only scale fonts based on DPI and not
                    text widths etc.

                        Sorry, no. Not really.
                        Only option is to tweak the html.
                        You can also render the widget to bitmap and control the size but that is not good quality.

                        We are in different time zones here on forum
                        so give it a day.
                        There might be someone that have seens this and found something for it. :)

                          Oh btw
                          You can test with
                          doc.setPageSize(paperSize)
                          and maybe get other results.

                            I tried to compile the tool with qt 5.7.

                            It looks better but the last row on the page is splitted onto 2 pages.
                            the css-prop word-break:keep-all does not work :-(

                              Only a subset is supported. QTextDocument is NOT a browser.

                                I hava a solution :-)

                                the problem is the css attribute "vertical-align:middle"

                                i remove this entry and so i have my workaround.

                                But i think this is a bug. From my point of view splitted rows shoud change to "vertical-align:top"

                                  Super good work!
                                  Well I not sure it will ever change the html on the fly.
                                  It will simply render it as it sees it.
                                  BUt this will be most useful to others.
