QML and Qt Quick

@GrecKo said in Restore TextInput after invalid input: onEditingFinished: m.setData(m.index(index, 0), text) No need to call setData either in 6.9, you can do it with onEditingFinished: model.display = text. Indeed. Simplifying further: ListView { anchors.fill: parent model: m delegate: TextInput { text: display onEditingFinished: display = text } } bool setData(const QModelIndex &index, const QVariant &value, int role) override { auto updated = (role == Qt::ItemDataRole::DisplayRole) ? value.toString().toUpper() : value; if (role == Qt::ItemDataRole::DisplayRole && updated.toString().contains('!')) { return false; } return QStandardItemModel::setData(index, updated, role); }

Give more details about the errors

Can you explain a bit more detailed what you mean with "combine multiple objects together"? Do you want the objects to be locked together but being able to rotate independently or something? If you simply want to disable collisions between objects you can use https://doc.qt.io/qt-6/qml-qtquick3d-physics-physicsnode.html#filterGroup-prop

Is this "Warning: Failed to load image: <path_to_ktx2>" the actual output or have you redacted the path?

@Niclas-Eisenhut hi and welcome to devnet, Can you also confirme this with the latest 6.10 release ?

@GrecKo Don't you handle key press signals from QML and invoke clearSingletons, clearComponentCache and loadFromModule in main.cpp? That was the impression I got from post #4 where you introduced the enable_qml_hotreload CMake function. Basically, I'm asking: how do you currently do a hot reload with a key press? Minimal working example or a bit more details would be useful since I'm a bit lost in the advice so far. I'm especially interested in your approach since you said that you maintain the same QML in production and for hot reloading: @GrecKo said in How to use qmlpreview?: ...but I believe using Loader is not the correct approach since that's different from the production code you want. In other words, you avoid the QML scaffolding needed for hot reloading (apart from catching the hot reload key press, I guess).

@Axel-Spoerl I found that the following code works: QQmlApplicationEngine engine; auto ctor = engine.evaluate(R"( (function() { this.name = "test" this.create = function(){ return "hello world!" } }) )"); engine.globalObject().setProperty("OaiClient", ctor); However, I don’t understand what the documentation means when it says that the globalobject properties should not be modified, and I’m unsure what the implications of doing so might be.

@fxam, stackoverflow.com/questions/73475849 might be of interest.

The first solution works pre 6.10. It puzzles me why the readwrite mode wasn't the default mode from the start though.

Hi, AFAIK, if you want to share stuff between different plugins, use a shared library that contains that stuff and link it to both plugins.

@Ashley-Paul You can't, those work based on roles. If your model is a list of QObject* I would suggest using https://github.com/OlivierLDff/ObjectListModel/ or QRangeModel as your model.

My full code you can look at pastebin, it works for me. For moderators: please look why the system rejects my message? [image: fae470cf-ff66-44ba-b543-ad6d11a3d330.png]

@fixgoats said in Impicit import 'QtQml' of QML module 'QtQuick' not found: @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. Install this package solved it for me (Qt 6.4.2 in Ubuntu 24.04). Thank you!

Hi @erenguness, and welcome! I don't recognize QmlHelper or that dialog box. They look like custom components, rather than built-in Qt components. So, please contact the author(s) of your "terminalQML" tool for further help.

What kind of graphics card do you have ?
