    Aha! found what I was looking for on a old blog post! Qt OPC UA will be available directly from the Qt installer for those holding a Qt for Automation license. [...] Users of one of the Open Source licenses will need to compile Qt OPC UA themselves. See here for a list of build recipes. this really should be clearly stated on documentation...

    Found the solution. Added this to the end of the function and now it the partitions filesystems are correctly formatted: newBootFs->create(*rootReport, bootDeviceNode); newRootFs->create(*rootReport, rootDeviceNode); Also I could delete this: if (devicePartitionTable->typeName() == "gpt") { qDebug() << "Setting partition type for GPT table"; newBootPartition->setType("C12A7328-F81F-11D2-BA4B-00A0C93EC93B"); // GPT GUID for EFI System Partition newRootPartition->setType("0FC63DAF-8483-4772-8E79-3D69D8477DE4"); // GPT GUID for Linux Filesystem } else if (devicePartitionTable->typeName() == "msdos") { qDebug() << "Setting partition type for MBR table"; newBootPartition->setType("0xEF"); // MBR type code for EFI System Partition newRootPartition->setType("0x83"); // MBR type code for Linux Filesystem }

    Hi, WARNING: I am NOT a lawyer. AFAIK, nothing forbids you to create such an application. That said, designer already exists and is language agnostic since it produces only an XML file that is consumed by uic. uic that is able to generate Python code. Also, if memory serves well, there's a new project file for Python projects that helps automate code generation so you might be missing on that for your projects.

    You can use it the same way it's done for the Qt libraries in your cmake file.

    @Aman55 Yes, you need to look at the stack trace pane in the debugger when that happens, so that you know where it comes from.

    Hi Slandino, I started working a few days ago on a project to mix Qt and flutter. I have already some working code, but it's using offscreen buffers (my final objective is to make a plugin to have a flutter layer in OBS) so I've not even looked on how to render to a window context. But the code may still work for you. I've commited the mess of code I wrote so far to https://github.com/hefsoftware/temp_qt_flutter (it compiles on windows, at least for me). Hope it will give you some help.

    @JonB Hi these I have already included. Also, I have seen a few examples at Github. I have tried to compile with MSVC as well as MinGW. These are the errors: moc_india_map_test.obj:-1: error: LNK2001: unresolved external symbol "public: static struct QMetaObject const QgsVectorLayer::staticMetaObject" (?staticMetaObject@QgsVectorLayer@@2UQMetaObject@@B) moc_india_map_test.obj:-1: error: LNK2001: unresolved external symbol "public: static struct QMetaObject const QgsRasterLayer::staticMetaObject" (?staticMetaObject@QgsRasterLayer@@2UQMetaObject@@B) after I try to run the project.

    Q
    Same issue, I have also got this cmake warning: -- qmlplugindump failed for org.kde.quickcharts. -- Could NOT find org.kde.quickcharts-QMLModule (missing: org.kde.quickcharts-QMLModule_FOUND) The qml plugin 'QuickChartsplugin' is a dependency of 'project', but the link target it defines (KF6::QuickChartsplugin) does not exist in the current scope. The plugin will not be linked.
