    I have been trying to give the HTML tag line to QString variable

    example QString qHtml = ("<button type="button">Click Me!</button>");

    but it is throwing error, is there any way i should define it

    but it is throwing error

    Which error is thrown by whom?

    QString qHtml = "<button type=\"button\">Click Me!</button>"; should at least compile fine.

    Qt has to stay free or it will die.

        @ManiRon

        Yeah, because your example

        QString qPrint = "("<button type="button">Click Me!</button>")";

        is different from your first example and different from mine. Just use the version in my post above.

            @ManiRon Ah, sorry. You need to escape the inner quotation marks. I've edited my post above.

                      your application with qtextdocument or QtWebEngine or other ?

                          Ok, see https://doc.qt.io/qt-5/richtext-html-subset.html, because last attributs of html are not supported like "<button>".

                            If I understand @cfdev's reference right, you will not be able to put a <button> tag (or for that matter an <input type="button">) on a QTextBrowser. I could be wrong(!), but I think it allows browsing only, it does not support adding "interaction" tags. It does support <a href=...>, though presumably for a URL only not JavaScript, if that might give what you want.

                            I have no idea what you're trying to achieve, but if it exceeds what QTextBrowser can do are you at least aware of https://doc.qt.io/qt-5/qwebengineview.html ? That is a Chromium-browser-widget, much more "heavyweight" than QTextBrowser but might be what you are looking for?

                                Again, I could be wrong :), but that is JavaScript and I don't think QTextBrowser is going to allow that. window.print() is JavaScript and I don't think that's going to work. Try something like:

                                <a href="window.print()">Print me</a>
                                <a href="javascript:window.print()">Print me</a>
                                

                                and see what happens (probably nothing).

                                You might instead have your code pull the HTML back from the QTextBrowser and do it yourself. Or, the QWebEngine I told you about will (should) allow window.print(); alternatively, as I do in my code, it allows you to handle printing yourself via e.g. https://doc.qt.io/qt-5/qwebenginepage.html#printToPdf. You can force using PDF either to the printer directly, or to a file, and you can also print directly to printer without going via PDF.

                                    So if you need any input to that, the actual error would be helpful ! :)
