General and Desktop

Hi, Without any code it's almost impossible to guess what might be going wrong. The best thing to do is to reduce your code so that only the faulty widget is present and exhibits this behaviour.

@Bob64 said in Very intermittent "QSocketNotifier: Socket notifiers cannot be enabled or disabled from another thread": I should try deferring the construction of the QTcpSocket until the thread has started Yes. Or try to reproduce it in a small example. Does not look that hard 🙂

@cadol001 You should thank @Abderrahmene_Rayene :-)

@Abderrahmene_Rayene Sorry to bring this old topic up as well. But I do believe if you do mainWindow()->statusBar()->addPermanentWidget( new widget,1); it will put the widget on the left side, 0 will be default to the right.

[image: 0105f950-f536-4bda-8a7f-6b4eeb4189df.png] Things in the middle getting squished, I have no idea why. The vertical size policy is preferred. The list widget at the top is set to minimumExpanding. The bottom most groupbox has also preferred vertical size policy. But this isn't getting squished. why.....

@big-dick said in how to exlucde sqldrivers?: the whole project add mysql dependency Your application should work just fine without Qt MySQL plug-in.

@Abelix hi and welcome to devnet, It was a long time ago but yes. You have to follow the specification and it works.

@Mark81 see sysctl net.ipv4.tcp_keepalive_time, you should reduce it to something reasonable for you (7200 secs is default afair).

@Mihir i think problem is in your gcc version. i also had that problem and i change my gcc version to gcc 9.5.0 sudo add-apt-repository ppa:ubuntu-toolchain-r/ppa -y sudo apt install g++-9 gcc-9 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-11 80 --slave /usr/bin/g++ g++ /usr/bin/g++-11 --slave /usr/bin/gcov gcov /usr/bin/gcov-11 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 100 --slave /usr/bin/g++ g++ /usr/bin/g++-9 --slave /usr/bin/gcov gcov /usr/bin/gcov-9 sudo update-alternatives --config gcc and try again with configuration

@JacobNovitsky Well, connect a slot to https://doc.qt.io/qt-6/qabstractbutton.html#clicked and in that slot set the string in QLabel using https://doc.qt.io/qt-6/qlabel.html#text-prop

I reviewed the old code and added the following definition: #define Q_ARG_OLD(type, data) QArgument<type >(#type, data)

@JacobNovitsky said in How to include my project B with Project A: I believe I need to make some kind of Library? Yes, you can make the project you want to include a library. Or you can simply add the code of that project to your other project. It really depends what you want/need. See https://doc.qt.io/qt-6/sharedlibrary.html for shared libraries.

Thank you so much for sharing your answer it was very helpful to me again.
