Qt Creator and other tools

It's mostly a tooling and operating system bug. See https://bugreports.qt.io/browse/QTBUG-117413 Qt Creator is creating a CMake project in such a way that will get result in long paths. CMake then gives this paths further to ninja / make and then to the compiler. GCC has this bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107974 and even though is an easy fix to add the manifest entry required by Windows ... nobody has fixed it yet. Visual C++ has the same issue, see https://developercommunity.visualstudio.com/t/compiler-cant-find-source-file-in-path/10221576 The only compiler that's fine is Clang. Ninja also requires a build from latest sources, since https://github.com/ninja-build/ninja/releases doesn't list yet version 1.12.0 which has the one line manifest entry that enables long paths. I usually say just switch to Linux or macOS, they are way more friendly to developers, and issues like this are non existent. Or ... just use c:/dev to have short paths 🙂

problem is solved with a command line in the console like git config --global http.sslVerify false reason was that QT creator intrinsically uses GIT when setting up a project and connects to a GIT server. The data from the GIT has self-certification and our company network does not allow this. With the command above we tell GIT that it shall not check the SSL certificate.

The output is displayed in the Terminal pane. In the Terminal settings you can configure not to have this functionality. See https://doc.qt.io/qtcreator/creator-reference-terminal-view.html#terminal-preferences and uncheck the Use internal terminal check box.

@AnneRanch QTextEdit *textEdit = mainWindow->centralWidget()->findChild<QTextEdit *>(); if (textEdit) textEdt->append("TEST TEXT"); else qDebug() << "Did not find any QTextEdit";

@warwick1996 you should start by installing the latest version of PySide6. It is now 6.5.3.

@Jonas-Kvinge Thanks for the feedback ! I am sorry, I lost track of this one.

@jsulm IPlugin is the interface. class EXTENSIONSYSTEM_EXPORT IPlugin : public QObject { Q_OBJECT //... } class HelloWorldPlugin : public ExtensionSystem::IPlugin { Q_OBJECT Q_PLUGIN_METADATA(IID "org.qt-project.Qt.QtCreatorPlugin" FILE "HelloWorld.json") //... } why not class IPlugin { public: virtual ~IPlugin() {} //... }; Q_DECLARE_INTERFACE(FilterInterface, "org.qt-project.Qt.QtCreatorPlugin") class HelloWorldPlugin : public QObject, public ExtensionSystem::IPlugin { Q_OBJECT Q_PLUGIN_METADATA(IID "org.qt-project.Qt.QtCreatorPlugin" FILE "HelloWorld.json") Q_INTERFACES(IPlugin) //... } maybe IPlugin has a signal?

@v3v439bm0 said in qtc.process_stub: Inferior error: QProcess::Crashed "Process crashed": I'm linking some libs, SDL2, Glew, OpenGL Do you build these libs using msys2? I'm asking because you can't mix MSVC++ and GCC.

I did try similar approach and it is sort-off working. Does that makes sense ? MWCCF->centralWidget()->topLevelWidget()->setWindowTitle("TEST windopw TITLE"); MWCCF->centralWidget()->topLevelWidget()->topLevelWidget()->setToolTip("TEST TAB TOOL TIP"); I have not figured out how to actually select desired Tab, so far only " top xyz..." is working. This approach is little cryptic ,but it would bypass the need for extra sub-funtion... ADDENDUM I think the above "topLevel" is OK for ONE level, it doe not makes much sense for multiple level... I like to modify / change my original post. Is there a way to scan thru the widgets / tabs to find a tab of specific title? I am still not sure how to find the correct widget - tab for example - pointer.

Command+leftArrow should work as well.

@KH-219Design Thank you for that. That's going to be useful.

@JacobNovitsky What QtCreator version is this?

Qt : 4.8.7 qmake: 2.01a issue : impossible to add qmake in “Qt versions” cause : qmake -query returns only a property ( QT_INSTALL_PREFIX ) fix : call “qmake -set <property> <data>” for all missed properties Ok, finally I have found the reason because QtCreator doesn’t add qmake in “Qt Versions”. It was not easy, I have had to discover what QtCreator does when someone selects qmake, QtCreator runs “qmake -query” for selected qmake. So I have compared the output of two “qmake -query” (one good and one my compiled Qt 4) and I have seen: good qmake provides more proprieties about qt my compiled qmake provides only one property (QT_INSTALL_PREFIX) It is very strange for me, because If I require a specific missed property (e.g. “qmake -query QT_INSTALL_BINS”) qmake provides the property info, but it is not be provided if I run “qmake -query”. So, the solution that I have found it is run “qmake -set” for all missed properties ( e.g. “qmake -set QT_INSTALL_BINS <folder bin>” ). Then when I call “ qmake -query” I see all properties. Now I am able to add qmake in QtCreator.
