The server page was not loading and the issue was I was using the server's newConnection() signal to immediately write the html page to the client. But you have to wine and dine the client first. I ended up connecting the newConnection() signal to a set up function:

void Server::handleConnection() { QTcpSocket* client = nextPendingConnection(); //client->setSocketOption(QAbstractSocket::KeepAliveOption, 0); QObject::connect(client,&QTcpSocket::readyRead,this,[=](){ handleRequest(client); }); }

You can then write the HTML content to the client in handleRequest()

@MH24 I don't know but a thread will (when it would work) also not speed it up.

I know this post is old, but ...

I had a similar problem changing the font on a QtextCursor in QTextEdit
I solved it by using setFontFamilies instead of setFontFamily

here a snip of my solution:

QTextCursor cursor = ui->textEdit->textCursor(); QTextCharFormat current = cursor.charFormat(); QStringList ffamily; ffamily.append(font); current.setFontFamilies(ffamily); cursor.setCharFormat(current);

@Chris-Kawa thanks 🙏

@Paul-Colby thanks this is really helpful

@Majed-Y
That's can do what you want....

In Qt 6.4 (on macos) Debug build does not generate javascript file...

The tag support in Qt objects is really simplistic and nowhere near like a browser. If you want browser type html use webengine. I think webengine is pretty heavy and probably not what you want.

I have found the answer!

it is about the drawContents method of QTextDocument.
There is a second parameter that you need to add in order to see the background image in your document.
It's the a QRectF object that represend the size of the rect that the background image will be clipped into.

void QTextDocument::drawContents(QPainter *p, const QRectF &rect = QRectF())
Draws the content of the document with painter p, clipped to rect. If rect is a null rectangle (default) then the document is painted unclipped.

So what I did is:

easuresDoc.drawContents(&painter, pdfPrinter.paperRect()); // We print TextDocument of the Measures into the document pdfPrinter.newPage(); // We inject the current page and continue printing on new page averagesDoc.drawContents(&painter, pdfPrinter.paperRect()); // We print the TextDocument of the Averages into the document pdfPrinter.newPage(); // We inject the current page and continue printing on new page inOutDoc.drawContents(&painter, pdfPrinter.paperRect()); // We print the TextDocument of the Inputs/Outputs into the document

pdfPrinter.paperRect is the rectangle of the page without the margin.

Also if you want the background image to be printed scaled with no repeat than you need to put the printer into QPrinter::PrinterResolution

QPrinter pdfPrinter(QPrinter::PrinterResolution);

syntax from documentation for border <width>px <border-style> <border-color>
That's mean it should be px after border.

@JKSH Oh wow, you're completely right. I didn't know qDebug() behaved like this, I assumed noquote() was the default. Thanks for the help, I don't know how long it would have taken me to find out.

@artwaw Yes, it works fine eventually :)

@Bonnie yes, i'm on Windows, thanks for the explaining!

@Jkimmy Thank you for your help.

Is it possible to to extend QLabel and implement my own paintEvent() that draws the text and draws the svg image?

It seems to work, but would problaby take alot of effort to get it right (i.e. to get the image in the right location everytime).

void MypLabel::paintEvent(QPaintEvent* event) { QPainter painter(this); const auto pos = QPoint(0, 16); painter.drawText(pos, this->text()); const auto posPixMap = QPoint(30, 0); auto size = QSize(16, 16); auto pixMap = QIcon(":/Resources/smiley.svg").pixmap(size); painter.drawPixmap(posPixMap, pixMap); }

@addr3ss No, it's not. Resources are compiled into the executable and can be easily extracted from there. What kine of information is it?

Tanks ....
Compiler accept only this way ...... ;-)

#ifdef QT_NO_GRAPHICSEFFECT QImage applyEffectToPics(QImage src, QGraphicsEffect *effect, int extent = 0) { if(src.isNull()) return QImage(); //No need to do anything else! if(!effect) return src; //No need to do anything else! QGraphicsScene scene; QGraphicsPixmapItem item; item.setPixmap(QPixmap::fromImage(src)); item.setGraphicsEffect(effect); scene.addItem(&item); QImage res(src.size()+QSize(extent*2, extent*2), QImage::Format_ARGB32); res.fill(Qt::transparent); QPainter ptr(&res); scene.render(&ptr, QRectF(), QRectF( -extent, -extent, src.width()+extent*2, src.height()+extent*2 ) ); return res; } #endif

Then use "<br>" instead of "\n"
