Re: [Interest] QML/C++ interaction in Qt6
Will Qt 6 still use the Meta information to access Qml properties or it rely more on compiled C++ now? I guess it still the same as before. Is the properties declaration of Qt for MCU (Qml lite or soemthign like that) be available (syntax wise, template)? That would leverage soo much redundent code to expose properties with get/set and changed event. That will be a slim fast for code that expose to Qml (to Meta data actually, Qml use the meta data) and maybe event make that layer disapear one day. -Original Message- From: Interest On Behalf Of Ulf Hermann Sent: September 11, 2020 6:20 AM To: interest@qt-project.org Subject: Re: [Interest] QML/C++ interaction in Qt6 > - Allow QML to access public properties of classes, even if these > public properties do not use `Q_PROPERTY` > - Allow QML access to classes that are neither `QObject`, nor > `QGadget` This is not planned right now.

Re: [Interest] No implementation found for boolean org.qtproject.qt5.android.QtNative.startQtAndroidPlugin
There was a discussion about this a while back into Slack QtMob into the
Android channel:
my android.pri now include the right manifest based on the build version:
MANIFEST_ANDROID_AMOTUS = AndroidManifest.xml
LIBS_ANDROID_AMOTUS = libs.xml
versionAtLeast(QT_VERSION, 5.13.0) {
AMOTUS_ANDROID_MANIFEST_FOLDER = "android-src/"
AMOTUS_ANDROID_LIBS_FOLDER = "android-src/res/values/"
}
!versionAtLeast(QT_VERSION, 5.13.0) {
AMOTUS_ANDROID_MANIFEST_FOLDER = "android-src/old"
AMOTUS_ANDROID_LIBS_FOLDER = "android-src/res/values/old"
}
QMAKE_EXTRA_TARGETS += $$androidSourceMaker("Amotus_Android_Manifest",
"/", $$AMOTUS_ROOT, $$AMOTUS_ANDROID_MANIFEST_FOLDER, MANIFEST_ANDROID_AMOTUS)
QMAKE_EXTRA_TARGETS += $$androidSourceMaker("Amotus_Android_Libs",
"res/values", $$AMOTUS_ROOT, $$AMOTUS_ANDROID_LIBS_FOLDER, LIBS_ANDROID_AMOTUS)
DISTFILES += \
$$AMOTUS_ANDROID_MANIFEST_FOLDER/AndroidManifest.xml \
$$AMOTUS_ANDROID_LIBS_FOLDER/libs.xml \
The androidSourceMaker is based on Luke Vear work:
https://github.com/lukevear/qmakeAndroidSourcesHelper
This allow to cherry pick part of code and happend it to the android source
folder, this allow multiple subrepos contributing to the android source folder
(we can only have one, which is limiting we you keep a lots of sub repos into
your projects).
Here is my source for it (I did sent it to Luke Vear already, but our needs
diverge, I should open source fork it, but it is right now into a private
repos):

Hi, You have to diff templates bundled with the two Qt versions and integrate manually the differences in the xml of your project. May not fix your case, though.

[Interest] QML/C++ interaction in Qt6
Hi, since Qt6 is going to include the strict QML subset, where everything can be compiled down to native C++, I was wondering if there are efforts going with that to improve interactions between the two languages along with it. Two things I am thinking of specifically: - Allow QML to access public properties of classes, even if these public properties do not use `Q_PROPERTY` - Allow QML access to classes that are neither `QObject`, nor `QGadget` Surely the fact that strict QML can be transpiled to C++ is going to help with implementing this. I think this would improve interactions between the two languages immensely. Are there any plans to allow something like this?
