@aha_1980 this just prints the click me in the html file

@ManiRon maybe you must assign a stylesheet ? how do you renderer it ?

[ManiRon]

@cfdev i am not getting you

[cfdev]

@ManiRon what is your html engine ?
your application with qtextdocument or QtWebEngine or other ?

[ManiRon]

@cfdev QTextBrowser and QTextStream

QTextBrowser qTextRep;
QTextStream qData(&qHtmlFile);
qTextRep.document()->setHtml(qHtml);

    qData << qTextRep.document()->toHtml();

QTextBrowser

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?

Actually i am trying to create a button to make the html report to be printed to a pdf . by giving the window.print() call

[JonB]

@ManiRon
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.

@JonB said in how to give the html tag line to QString:

"javascript:window.print()

I tried both and this one (<a href="javascript:window.print()">Print me</a>) worked and asked for which printer to use and i select one suddenly it says some error has occured

some error has occured

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