@ankou29666 It's most often easier to directly go to https://download.qt.io ;)

@jalef36678 said in Help with Combining C++ and QML in a Qt Application:

because the project entails developing a desktop application that needs a dynamic and responsive user interface.

Because QtWidget isn't responsive and dynamic at all?!

managing data models

Are you thinking of QML Models or the QtWidget ones for your data?!

What is the best way to connect data between QML and C++ while preserving scalability and performance?

There are more than enough examples out there, even official one.
Check here:

https://doc.qt.io/qt-6/qtqml-cppintegration-overview.html https://doc.qt.io/qt-6.2/qtqml-cppintegration-topic.html

Although I've heard of using signals and slots, I would like more precise instructions or an example.

Signals & Slots can do the job for you as they are available in both -- QML and C++ -- contexts.

https://doc.qt.io/qt-6/qtqml-cppintegration-interactqmlfromcpp.html#connecting-to-qml-signals

Another way is working with Q_INVOKABLE and/or Q_PROPERTY.
Every time when a property changes, it triggers its NOTIFY function/signal.

Is it possible to dynamically generate or modify QML components from the C++ side?

In general yes.
You can either load a pre-defined *.qml file at run-time or you create the "component definition" on the fly as string and feed it into the QML object factory to generate your QML component.
Where you invoke this, is up to you... on button click in QML or if some background action in C++ triggers the QML engine to load something...

They should change tool ! ^^

Original post edit: the deadline for the CfP was postponed to September 13th, 2024!

It's back online now :)

Sorry for the late reply (I was on vacation). The upvoters' names now also work for me. Thank you very much! I don't have any further complains about the new forum style.

@keksi-venksi said in QML - Car infotainment HMI or IVI open source project Demo:

what is the question here and what solution you need ?

Why do you answer on a seven year old topic with a wrong question? The topic is in the showcase section - so what should be asked?

Hello,
Very interesting, could we get in touch to talk about this.
I'm eymeric o'neill and I an either available on LinkedIn or teams:
eymeric.oneill@gmail.com

It's released now: https://www.qt.io/blog/commercial-lts-qt-5.15.17-released

@FeRDNYC said in Forum Update May 2nd:

I can't see any of the forum navigation interface, until I remember to scroll back a bit to make it appear.

As a practical, constructive suggestion in that regard, perhaps the toolbar could "reattach" itself to the Page's main scroll context at the very bottom, so that it scrolls back into view beneath what's now the bottom of the page? That way, it would reveal itself once you've scrolled DOWN past all of the other content, as well as when you scroll up.

nice! congrats Chris-Kawa

edit: nomination period extended to the 22nd of December :)

Hello Amanda, and welcome!

I too would like to avert a climate/ecological breakdown. I've followed geosequestration experiments/pilots with interest but none seem to have achieved their goals yet, so I wish you the best in your project.

As for the Qt Creator license issue, it looks like you installed a Commercial (possibly Evaluation) version of Qt? Do you remember which link you got it from?

Anyway, please try uninstalling it, and then reinstall from https://www.qt.io/download-open-source instead. No funds are needed to use Qt under an open-source license, although non-monetary contributions to the Qt community (in the forum of bug reports, patches, community engagement etc.) are always welcome.

@Beanhanp If you are on Linux do you even have any .chm files to convert?
