@booter Do you have a question? If you get this error - did you install the packages mentioned in this thread?

@dondioci You said you want to customize the stylesheet, how would you change that by stylesheet even if you can rebuild the ifw? The configure command is part of Qt source code. And this step in the documentation is only needed if you want to build Qt by yourself. If you already have Qt then simply follow "Setting up Qt Installer Framework" chapter in the documentation. Well, usually we need to build Qt before building ifw because ifw needs to be built with static Qt.

Hi, Are you looking for the Video Widget Example?

@JonB Hi, thanks for all the help, I finally figured it out, it did have to do with the env variable for structureanalysis, even if I ran it inside cmd there was trouble. I had to send the full path for where structureanalysis is located in my shell script. it worked

Hi, What happens with your model ?

@Roobarb said in Use public slots or private slots?: @dheerendra But if you make the slot private, how can something outside of the slot class call connect() using it? When I try to use a private slot in my connect() call, the compiler says: error: 'onMessage' is a private member of 'my_slot' Hi, That's where you have to properly analyze whether having that slot public is a valid use case or not. Just making it public because it allows connection is not a good reason. Check your architecture first.

@SGaist Thank you ... building Qt out-of-sources was successful. I found this link which was very helpful in explaining how to do it: https://gist.github.com/black13/3a55ed9afb5ba9ab5119ebd271a2aaa5 I saw another reference to this in the Qt documentation, but can't remember exactly where I saw it (EDIT: this was at the very bottom of the previous web page: https://doc.qt.io/qt-5/linux-building.html). Now I was able to easily install both a debug and a release version of Qt with this method by setting different -prefix arguments.

@hskoglund I want to using Win32 API for place the tray icon in the notification area

Hi, your BLOCK is "040904b0" means English Unicode but maybe first try Windows 1252: "Copyright 2023 \xA9 More text" and then perhaps UTF-8: "Copyright 2023 \xC2\xA9 More text"

@Rockerz you can use the chunk property for this in the stylesheet, but it won't allow you to show different size of the bar I think: https://doc.qt.io/qt-6/stylesheet-reference.html#chunk-sub

Thanks for the tips and @hskoglund , the crul --lib option is a really cool trick I will never forget. And @SGaist, thanks for the checklist, I'll keep it in mind. 30 years of C++, quite some time with C-level sockets and newbie on modern networking in Qt I need all help I can get. I found the problem and it is a typo. I rearranged the code and the URL-port is set after I have used the object to initiate the network request. I shifted the lines and things are working as supposed. I figure I just needed some time away from the code to actually READ the code ;)

I still didn't find a solution to this, does anyone have another idea?

@wasawi2 wooops sorry my newby fault!! I just had to remove the auto in the cpp file. Therefore: linewidget.cpp //![1] m_series = new QLineSeries; //![1] linewidget.h QLineSeries* m_series = nullptr; Everything under control now. Thanks again for your fast answer @kkoehne.

Hello Sierdzio and All! I didn't get the source code from the package. I used the command. git clone git://code.qt.io/qt/qt5.git qt6 perl init-repository I don't need QtWebEngine by itself, but I want to try to do something on WebAssembler, and for it I need Qt WebEngine. I know about the ready-made installer, but it's more interesting to assemble it yourself. In addition, I tried to fix the source code of the Qt library itself. With best regards, Navadvipa Chandra das.

Here is a configure line I'm using to build Qt 6.4.3 statically on Windows (and please remember to respect the license! Static builds usually mean commercial license of Qt!): ..\qt-everywhere-src-6.4.3\configure.bat -static -static-runtime -plugin-manifests -no-openssl -schannel -c++std c++20 -dbus-runtime -confirm-license -release -nomake examples -nomake tests -prefix ..\6.4.3 -no-icu -no-glib -qt-doubleconversion -qt-pcre -qt-zlib -qt-freetype -qt-harfbuzz -qt-libpng -qt-libjpeg -qt-sqlite -qt-tiff -qt-webp -skip qtcoap -skip qtopcua -skip qtscxml -skip qtwebengine -skip qt3d -skip qtconnectivity -skip qtlanguageserver -skip qtpositioning -skip qtsensors -skip qt5compat -skip qtdatavis3d -skip qtlottie -skip qtquick3d -skip qtserialbus -skip qtwebview -skip qtactiveqt -skip qtquick3dphysics -skip qtserialport -skip qtquicktimeline -skip qtwayland -skip qtcharts -skip qthttpserver -skip qtremoteobjects -skip qtspeech -skip qtwebchannel -skip qtmultimedia cmake --build . --parallel cmake --install . Mind you, I am using MSVC to build, I am not sure if the same will work for MinGW.
