Hi Dirk,
in my apps ATM I'm only using one qt qml module, so I'm doing
engine.loadFromModule(...)
see https://t1p.de/ekkeCMakeQMLModule
Have no experiences yet if you have to deal with more modules. Later
will modularize my apps, much other refactorings must be done before ;-)
but you should not do multi engine.loadFrom...
good night...

Hi Ekke,
Thanks so much for the quick response.
This is a massive project (Subsurface-mobile) that we build with CMake.
Thanks for the link to your site with an explanation... this feels
like I'm **ALMOST** there...
I had already added QML_ELEMENT to the class header.
In the existing code, we load the main.qml from the resource system with
engine.load(QUrl(QStringLiteral("qrc:///qml/main.qml")));
I added a second line
engine.loadFromModule("subsurface/mobile/main", "QMLProfile");
Rebuilt things and get:
INFO: QQmlApplicationEngine failed to load component
INFO: qrc:/qml/main.qml:8:1: module "subsurface.mobile.main" is not
installed
INFO: QQmlApplicationEngine failed to load component
INFO: <Unknown File>: No module named "subsurface/mobile/main" found
Do I need to do anything else to ensure that the type is visible and
subsequently the module is found?
Thanks again for your help!

Instead of qmlRegisterType you should use QML_ELEMENT

Hi there,
I've been trying to figure out how to port a QML app from Qt5 to Qt6
and have been unable to solve what seems like a fairly basic issue.
In the Qt5 version, I was able to make a class available from C++ by
simply calling
...
qmlRegisterType<QMLProfile>("org.subsurfacedivelog.mobile", 1, 0,
"QMLProfile)
...
in the C++ code and then using
import org.subsurfacedivelog.mobile
in the QML file in order to then be able to use that type as
QMLProfile {
...
}
in the QML code.
When I try this code unmodified, it compiles fine, but at run time
tells me that it cannot find the org.subsurfacedivelog.mobile module
when it encounters that import org.subsurfacedivelog.mobile line.
So I tried some searching and found several pages in the Qt6
documentation that all seem to imply that this isn't how things
should be done in Qt6 and that instead I would need to go down the
route of defining a separate QML module with its own compile unit
(is this true? why would you disable this core feature???)
And then trying to do that, I fail to get the module to compile with
missing include paths.
If it turns out that that's the only way to go, I'll happily give a
lot more details on this issue -- but I'd love to first get back to
the previous approach.
Is there still a way in Qt6 to register a Type with QML without
having to create separate modules?
Thanks
/D
