General and Desktop

@wesblake 3 days in and I have gotten nowhere. I'm reproducing this on any 6.X version of Qt in App 2, still works fine in any of those versions on App 1. Test team does swear the last version (6.4.3) it didn't happen but now they're seeing it in the last released version too, so I'm wondering if it could be some Windows OS update that started it?

@Pl45m4 said in QButtonGroup difficulty: btnGrp->button(someId)->setChecked(true); Yeah! Nice!

@AnneRanch So do I - expect too much...I expect before replying to once a while READ the post - at minimum. And I expect people to read the documentation or use google before posting a question, but sadly very, very few will do so. Refraining from social innuendos = such a telling person to expect too much - as a secondary expectation. You haven't yourself set a topic to solved in 2-3 years. And you also posted here yourself that you will not set topics to solved: It is your opinion that posting "solved" will help others , however , it is my opinion it will not, therefore it is pointless to argue about it. It's by no means an innuendo, it's stating a fact. .and it would be foolish to admit I had a typo, right ? no it would not, we all make errors big and small. A simple typo has cost me myself days, that was not too long ago too. No-one will make fun of you or think less of you, for something like that.

thank you for your help. it is working now. for anyone who may face the same error , you have to include the header file which is #include "../qgroundcontrol/libs/mavlink/include/mavlink/v2.0/ardupilotmega/mavlink_msg_rangefinder.h" in you vehicle.cc file .

@SGaist All right, thanks for you answer.

@Alxi11 said in How to compile icu statically into Qt 6?: I want to compile icu statically into qt so that my app won't search for icu libs. ICU decides itself if it is static or dynamic. Through package managers you always get dynamic libraries. There is nothing Qt can do about this. Most likely, you have to compile ICU statically yourself. And then you need to teach Qt to link against the static library. This basically means that you also need to compile Qt yourself and during Qt compilation point it to your static ICU library. Once you have a Qt library compiled to link against a static ICU, you can use that Qt library just like normal inside your own applications. @Alxi11 said in How to compile icu statically into Qt 6?: Should I add -static-runtime to my configure command or add cmake options? -static-runtime is just about the C or C++ runtime. There is no command to link to a dynamic library as if it where static. Most likely the actual problem you are trying to solve is that not everybody has the right libs installed on their machine. We are using linuxdeploy and linuxdeployqt to create an AppImage which has all dynamic libraries included (there is also snap and flatpack). Only downside: these check that you are running on an older Linux distro in order to make it compatible with most supported Linux versions out there.

i reply by my own: QWebEngineProfile::defaultProfile()->settings()->setAttribute(QWebEngineSettings::PluginsEnabled, true); QWebEngineProfile::defaultProfile()->settings()->setAttribute(QWebEngineSettings::DnsPrefetchEnabled, true); QWebEngineProfile::defaultProfile()->settings()->setAttribute(QWebEngineSettings::ScreenCaptureEnabled, true); QWebEngineProfile::defaultProfile()->settings()->setAttribute(QWebEngineSettings::PdfViewerEnabled, true); QWebEngineProfile::defaultProfile()->settings()->setAttribute(QWebEngineSettings::JavascriptEnabled, true); QWebEngineProfile::defaultProfile()->settings()->setAttribute(QWebEngineSettings::Accelerated2dCanvasEnabled, true); QWebEngineProfile::defaultProfile()->settings()->setAttribute(QWebEngineSettings::TouchIconsEnabled, true); QWebEngineProfile::defaultProfile()->settings()->setAttribute(QWebEngineSettings::WebGLEnabled, true); QWebEngineProfile::defaultProfile()->settings()->setAttribute(QWebEngineSettings::HyperlinkAuditingEnabled, true); QWebEngineProfile::defaultProfile()->settings()->setAttribute(QWebEngineSettings::PluginsEnabled, true); QWebEngineProfile::defaultProfile()->setPersistentCookiesPolicy(QWebEngineProfile::ForcePersistentCookies); QWebEngineProfile::defaultProfile()->setCachePath("/home/xx/Doc/coockie"); QWebEngineProfile::defaultProfile()->setPersistentStoragePath("/home/xx/Doc/chache"); seems these settings is enought and no need other ..... after some test I see significant improovemnt of loading page addin the last pieces of code .... and no see better result with the original code posted ..... I see differences only if leave aout "profile" settings ..... but only because chache and coockies is not used in "standard" mode .... Perhaps if you have some eavy process run on gui qwebengineview show web pages slowly with ethernet connection at 1Gb .... where onpecv show realtime grab in fluent way ...... So seems qwebvidgetengine is ok only for real small opertation on web ..... like dowload somethings or starting a chat ..... not for sure for play a video in streaming for example ..... or maybe I make something wrong (on that pc I have the latest chromium and chrome version). best regards

@manuelschneid3r Use a proper memory analyzer like Valgrind

@bestmyf_001 Assuming that data_value is actually a QJsonArray... what is the value of i and how many elements are in the array? See QJsonArray::at()

@__d4ve__ I used socket->bytesAvailable() and it seems to solve the problem.

@Mighty_Pig Very well, I’ll look into it then.

@Sofiakim - Note that I am using QtQuick/QML (not Qt Widgets) I assume that Design Studio as well as qtcreator would provide tools to create menu bars and menus, but I cannot for the life of me find those tools in qtdesignstudio (4.4.0) or qtcreator (12.0.2, 13.0.0). Can you please tell me specifically where to find these menu-creation tools? Thanks!

@ananomous Do not use a "-" in prefix... WRONG: ./configure -release -prefix /usr/local/Qt-5.7.0 OK: ./configure -release -prefix /usr/local/Qt5.7.0

Have you tried running make install after you build the project? Are you sure that test.dll, which is indeed a strange "header", lives in the root directory of the current disk?

Setting the edit trigger comes to mind.

Upon further inspection, it turned out that the problem only occurs when the widget containing the QGraphicsView has the attribute Qt::WA_TranslucentBackground set. setAttribute(Qt::WA_TranslucentBackground); Is this really the intended behaviour or might this be a bug?

@Christian-Ehrlicher Thank you for help! Solution was found. I just missed in my garbage code, and i did't totally understand what i was doing for a lot of time.))))
