For the layout on the delegate you can use a grid layout or cascaded horizontal/vertical layouts, that really does not matter. However, if you are not familiar with basic widget layouts I would suggest starting with something more basic than delegates. E.g. you can first setup the model/view, then make a standalone widget to be used as delegate, and finally setup the delegate.

Did you find a solution / workaround for this issue? I am experiencing the same issue. I realized that it is somehow related to CPU stress, however, could not find a solution yet. Any hint would be appreciated, thanks.

@Bonnie That made it. I just needed the c:/users/qt/work/qt target, though. And no CDB paths at all. I'm pretty sure I used the Add Qt sources button before, but ATM, IDK (and IDC) about what happened. Thank you very much! I've been on this for a long while.

@AnneRanch said in Open source ....: Could somebody with experience analyzing Qt Open source code help me to find actual code for "code formatter / beautifier " . At least give me some pointers where to start looking - github link ? Is https://github.com/qt/qtbase good place to start ?. The Beautifier is in Qt Creator IDE. qtbase contains Qt libraries, not the Qt Creator IDE. https://github.com/qt-creator/qt-creator/tree/master/src/plugins/beautifier yes I have asked this before AND GOT NOWHERE. You can add a link to your original post here.

Hi It has to be the right role. QWidget::backgroundRole() is not used it seems. Try QPalette p = ui->textEdit->palette(); p.setColor(QPalette::Base, Qt::red); // BG p.setColor(QPalette::Text, Qt::white); // (plain) TEXT ui->textEdit->setPalette(p); [image: 1byfHV.png]

Yeah, this started appearing a few versions ago, around 5.13 or 5.14. I think some bug fix must have changed QQmlEngine destructor or something. In every case I noticed these TypeError logs, it was enough to change parenting or initialization order to fix the issue.

Use the selectedFilter output parameter to get the information.

@qwe3 try https://doc.qt.io/qt-5/qtextdocument.html#textWidth-prop

@Flaviu-0 said in CMAKE_MAKE_PROGRAM is not set.: CMake Error: CMake was unable to find a build program corresponding to "Ninja" Your problem is not qt related. https://ninja-build.org/manual.html cmake uses ninja in your case. Try to install ninja and you will be all right.

@jan-tosovsky after resize event, the image position has to be adjusted for center alignment. Otherwise, its position will not change.

@jsulm yes you did but my problem is not about deploying. I cannot run my project on qt creator

Actually the usual way is just deploying the translation files with the executable file. When you use windeployqt tool on Windows, some translation files will be copied just like the plugins by default. If you want to add them to the resource it is also possible. I think you can't use MACROs in qrc file. But you can use them in the .pro file and let it generate a qrc file for you. qm_file.files = $$[QT_INSTALL_TRANSLATIONS]/qtbase_bg.qm #can be multiple files qm_file.base = $$[QT_INSTALL_TRANSLATIONS] #add relative alias automatically qm_file.prefix = i18n RESOURCES += qm_file This will generate a qrc file qmake_qm_file.qrc in the build folder and add it to the Makefile. Then you would be able to access the file by :/i18n/qtbase_bg.qm.

The Build & Run pages magically appeared again. Must have been something wrong with the kits afterall.

@J-Hilk said in My modbus connection status stay on connecting forever.: connect(modbusDevice, &QModbusTcpClient::errorOccurred, this, [](QModbusDevice::Error error)->void{qDebug() << "error happened :" << error}); check this link you will find a solution: https://forum.qt.io/topic/125391/modbusclient-as-a-console-application-stuck-in-connectingstate-loop/3

@eyllanesc Thank you! Indeed, the (2,2) case was empty...

@AnneRanch said in Is "moc" actually helping to debug?: Let me put this the silliest way - if I do not have an object BT_TabWidget constructed nowhere in the code then I am getting "you are missing destructor SOMEWHERE " from all of this. And I will not ask why I am not getting "no BT_TabWidget (object) found " instead., So I will go back to code and verify all BT_TabWidget CODE myself. When you compile stuff, the assembly is generated for the classes not the objects. There's no requirement that you must have an instance of some class to have the latter compiled into code. Or to put it the silliest way I can think of: classes are not objects, nor vice versa. As far as C++ goes, all virtual functions shall be defined if they're not a pure virtual for the build process to succeed, and if you go through your code I'm sure you're going to find out that this particular class has a destructor, which was declared (hence it's an override due to its base class' destructor being virtual), and that destructor hasn't been defined. @wrosecrans said in Is "moc" actually helping to debug?: I don't have any children. Can you tell me where my son Gary isn't? It's impossible to point to a specific place and say that's where something isn't. lol! If it doesn't exist, it isn't everywhere. We could argue some quantum mechanics about that ... ;)
