@patrickkidd what exactly have you found?

@SGaist It is a general practice to use touch screen in this field. Not yet. I will take a look at it. Thank you for your advice.

@apalomer said in QTextEdit does not apply css to html table: I am using QTextEdit to display some markdown content. I am using QT version 5 and cannot move to 6 to use QTextEdit.setMarkdown. QTextEdit.setMarkdown was introduced in Qt 5.14. If you're using something older and have the option to upgrade, the 5.15 series is worth a look. Maybe it will help, or maybe it will introduce a new problem. As you can appreciate, I can add a CSS style to the document (h1 and h2) in the QTextEdit. However, the table part of the CSS is not being applied (there is no border). According to Qt documentation the table properties that I am using are supported. Any idea on what can I do to apply the table style? QTextDocument's html and css capability is pretty limited, and frequently involves a conversion from the input to what is actually used by the widget. Look at the html being generated from the markdown, and at the html that QTextEdit.toHtml() returns. There may be a more specific css rule that is automatically applied.

@Christian-Ehrlicher I see, so I figure I have two options here: stop using the QThread, but that is not my favored option because I would like the device scanning to happen reliably even when the GUI thread was frozen (that was the reason why I did this move in the first place). I could also create the QThread later move the Device to the "main" thread before it is passed to DeviceHandler::detected. Trying this out it seems to work, and it matches "moving the ownership" of the Device instance to the rest of the app. Marking this as solved, thank you for your help!

OK it wasn't too difficult in the end, you can use the transport() function from QMqttClient and cast it to a QSslSocket pointer as long as the transport type is SecureSocket. QIODevice* d = m_client->transport(); if (d) { QSslSocket* s = dynamic_cast<QSslSocket*>(d); if (s) { qDebug() << "Protocol:" << s->protocol(); qDebug() << "Session Cipher:" << s->sessionCipher(); qDebug() << "Session Protocol:" << s->sessionProtocol(); } }

@jsulm Thank you, I didn't have that in mind at all. I extracted it into a function that I was calling from main, but I have just seen that the documentation says that it doesnt take ownership of it, so it indeed goes out of scope. Moving it back into the main function fixes it!

@JonB Hi! Thanks for your quick reply. That does make sense. Kind regards, fpsio

@jsulm Hmm okay I am not sure of how to do this. I just checked the lib folder and it has the file libQt5SerialPort_x86.so @JoeCFD Hi, I tried in both it gives the same error Sorry for the late reply

@feri Excellent. I had not recognised the Qt5-Qt6 differences.

@swurl then the most simple is to read the code of QDial and create your own based on it.

Hi and welcome to devnet, Are you using some pre-built libraries in your project ? Did you check them to ensure they contain arm64 code ?

@JonB I read that paragraph dozen of times but I didn't realize the braces are intended to be literal! I understood it's just to point out I need to place the variables inside a function! Anyway it still wasn't enough! I had to add: delete _model; even if the docs says: Clears the model and releases any acquired resource.

@benjamin_jaeger After you have addressed @jsulm's questions. And maybe tried this in a small, standalone program, not wherever you are now in a big application, with goodness knows what else maybe included. In your https://stackoverflow.com/questions/77389686/q-assert-issues-when-porting-projet-from-qt-5-15-2-to-qt-6-5-2 you were asked what compiler/versions/C++ level you are compiling with?

@enjoysmath That's a set, list, group, vector or a number of other things. It's not an alphabet, because it doesn't represent phonemes (unless you can make a sound of pizza). We're talking about sets of characters, so linguistic definition of an alphabet is better suiting than that of a formal language theory. You learn your ABCs in a language class, not in math class.
