QML and Qt Quick

@JonB Hello my dear! Using the QML profiler, I was able to identify the origin of the problem. I currently have 3 js files: app.js, main.js and countries.js. The main.js file contains my main js functions. The countries.js file should contain the list of countries in a constant and functions to manipulate them. I import all my js files into app.js. The countries.js file was recently added. While I was working there, I had an emergency. So I stopped the work by leaving in countries.js an empty array const and a function that does nothing. const list = []; function func() { } This is what was causing the problem. I just commented out the countries.js import statement in app.js and it fixed the problem. Thanks for the guidance.

Hi, there's a bug in Qt 6.7.1 and 6.7.2 related to what you're experiencing: inputMethodHints are being ignored in Android. Lucky it's fixed in Qt 6.7.3 and 6.8 :) https://bugreports.qt.io/browse/QTBUG-125410

@Markkyboy My QtCreator version is 10.0.1 based on Qt 6.4.3 (Windows) Designer is not a part of QtCreator I enabled QtQuick plugin I am unable to access your Github at any time, Try again, there's an issue with github. At least I want to understand why the progress bar doesn't work, it's crazy !

surprising, but it turned out to be correct qrc:\res\heaven.png Why ?

Thanks a lot, it fine now ![image: f7323171-190d-4df1-adff-e61f66ae9088.jpg]

oh yep, didn't notice that detail

@BILAL-KHAN-34 Put the mouse cursor over the yellow warning icon to see the pop-up with the information about the problem.

@Charby said in How to pass an array (list) filled with custom data to QML?: console.info(gameModel[0].mark) // should be 0 console.info(gameModel[0].mark) // should be 1 console.info(gameModel[1].mark) // should be 1 :) @Anton1978 As @Charby wrote above, you can access the list data using the index and the member you want to address, like this: (with the changes shown below) // return a list reference // consider to make it const if you dont plan to modify the list later (only in C++ code) Q_INVOKABLE const QList<MinePlace *> &getModel() { return _forSend;} In QML something like property var gameModel = gamecalcID.getModel(); for (var mp in gameModel) console.log(mp.mark)

I'm not really sure this could achieve what you are looking for. but ListView has (header and) footer properties. also footerPositionning. Have you looked in that direction ?

This is what I get when it gets unresponsive: [image: b2074342-90b3-45fc-9dd7-c9d8a9c428e9.png]

I'm still using Qt 5 but I had a look at the doc and it seems to me that the API exposed to QML is more limited in QtGraphs than it was in QtCharts. The append method is available in the QXYSeries C++ implementation class but not in QML as far as I can see. You might need to write a function in some backend C++ code that you expose to QML. This function would accept a QXYSeries* and you will be able to access append in the function's C++ implementation. You will be able to pass your scatterSeries object to this function from QML and it will be received as a QXYSeries*.

@Kai-Nickel said in How to access QJSValue's QQmlEngine in Q_INVOKABLE to support callback pattern for C++ models: Just a lucky shot: did you try using qjsEngine(this) instead of qmlEngine(this)? I did not and I'm happy to report that qjsEngine() does work! Looking at the source code of qmlEngine() vs qjsEngine() it is obvious why: qmlEngine() only works if there is a qml context for that object. I was under the assumption that qmlEngine() simply called qobject_cast<QQmlEngine*>(qjsEngine(obj)), which is why I didn't look at the differences between the two. Evidently my assumptions proved wrong. QQmlEngine *qmlEngine(const QObject *obj) { QQmlData *data = QQmlData::get(obj, false); if (!data || !data->context) return nullptr; return data->context->engine; } QJSEngine *qjsEngine(const QObject *object) { QQmlData *data = QQmlData::get(object, false); if (!data || data->jsWrapper.isNullOrUndefined()) return nullptr; return data->jsWrapper.engine()->jsEngine(); }

@Axel-Spoerl thanks for answer. It explains a lot. Initially, I thought it was my bad and I did something wrong. I have windows 11 as well as it was described there, that same problem

@sable I was having a similar issue on Ubuntu as well. I needed to install qml6-module-qtqml and that fixed the warning. Which is odd because the base project compiled just fine before then.

My bad. You have to import the URI, so it should actually be import Test03

@JohnKS Wow, I just spent like an hour trying to figure this out and copying detailed tutorials verbatim to try and get it working and it's this non-default flag that apparently doesn't always need to be set seeing as it doesn't appear anywhere in Qt's examples. It would be really helpful if this was mentioned more prominently somewhere.

I got the following solution connect(qGuiApp, &QGuiApplication::focusWindowChanged, this, [this](QWindow* focusWindow) { if (!focusWindow) { return; } auto windowList = QGuiApplication::allWindows(); windowList.removeIf([focusWindow](QWindow* w) { return !w->isVisible() || w->transientParent() || w == focusWindow; }); // Attempt to restore windows in the order in which they were opened. std::sort(windowList.begin(), windowList.end(), [](QWindow* l, QWindow* r) { return l->property(FOCUS_TIME_PROPERTY).value<qint64>() < r->property(FOCUS_TIME_PROPERTY).value<qint64>(); }); for (auto window : windowList) { qDebug() << "Raise" << window->title(); window->raise(); } focusWindow->raise(); focusWindow->setProperty(FOCUS_TIME_PROPERTY, QDateTime::currentMSecsSinceEpoch()); });
