No, do it once in the constructor. The setting will apply to all future requests.

Hi, How did you set the QLabel on your QScrollArea ? If you put it in a layout on the scroll area then that's wrong.

@aaaaaaaaaaaaaaaa said in shitty question: @koahnig i don't need vs2019 on my computer to use the msvc compiler on Qt ? No, the C++ build tools are enough. Please, update your thread title to something meaningful.

Finally came back to this problem (testers wouldn't stop bugging me about it). Found a potential solution! QQmlProperty::write(QObject*, const QString& name) It doesn't seem to be documented, but calling this function seems to break any existing QML bindings on the specified property. So I just create a separate WRITE function for my aliased property: Q_PROPERTY(int number READ GetNumber WRITE SetNumber NOTIFY NumberChanged) Q_PROPERTY(int numeral READ GetNumber WRITE OverwriteNumber NOTIFY NumberChanged) void OverwriteNumber(const int value) { QQmlProperty p(this, "number"); p.write(value); } Seems to work for me. Basically gets around the problem of C++ being unaware of the binding by writing to the property through the QML context, I guess. It's probably much slower than calling the setter directly, so probably not ideal for properties that change frequently, but it will suffice for my purposes.

Actually, 100% my fault. Things are plenty fast. I had an extra call to size() in my method that I didn't need, and that is a slow call. Thanks, Gerald

@JonB Haha. Perfect answer if any user asks :)

@Garf Please do as that book is actually the best we got so far and I never found any other book that was better. Also as soon as you start to make a real biz application where animation and interface is less important than the actual data processing, you will find that https://doc.qt.io/qt-5/qtqml-cppintegration-overview.html https://doc.qt.io/qt-5/qtqml-cppintegration-topic.html becomes the reference and a tutorial with a more beginner friendly learning curve would be golden. (IMHO)

@mrjj yes, thank you I've just found a way to show end of file character in notepad :)

Hi You are most welcome. Thank you for sharing the solution as the use case might be pretty common and it is indeed not optimal having to scroll all the way to the bottom to be able to scroll sideways.

@mrjj Thank you so much. This takes some worry off my mind.

@Mohammadreza99A Why do you want to access a private variable from another class? Don't do that, use getter/setter. When using threads you would need to synchronise the access to avoid race conditions. Better would be to use signals/slots to exchange data between MyClass and Worker.

Finally I have found error in my code. It was hard because of weird processing. QString::split() works fine. But what about QRegExp - I do not remember why I used it instead of QRegularExpression. May be it looked simpler. This code was redesigned and regular expression was much more complex at beginning.

Nice! Happy coding

From the looks of it, you only want a copy of the content of the tree item.

Hi, Modify the protobuf_decl.output, protobuf_impl.output and protobuf_impl.depends paths to point to where you want.

After a lot more testing and comparing between systems with and without the issue, is does not seem to be related to network reliability after all. System sending regularly and constantly are OK systems spending sporadically take up ever more memory. When about a 100K is sent every 10-20 minutes and additional 40Mb is used up daily compared to sending ever minute. This memory in not released if QNetworkAccessManager is destroyed. Memory is taken during QnetworkAccessManager::post() and the amount can be anything between 2-300K to 3MB at a time and is not related to the amount of data sent. Does anyone have experience with cacheing in QNetworkAccessManager? What is cached by default and how to control it?

I can open this port by: So, as I said, the problem is not in O_LARGEFILE. There are just a few codes in QSP sources in github link This is not a sources, the sources is in.

@jsulm Oh, I didn't notice that the example the link said "For example, Manufacturer A could have an RSSI max value of 100 while Manufacturer B will return RSSI values anywhere from 0 to 127. " So,maybe rssi() == 127 means this signal is the best. Thank you so much!
