How to custom style qml virtual keyboard in Qt 6

[bambooMZL]

My QT version is 6.4.1.
Now, I am setting the custom style for virtual keyboard.

But it can't work.

The code
QQmlApplicationEngine engine;
engine.addImportPath((":/MyStyles"));
qputenv("QT_VIRTUALKEYBOARD_STYLE", ("MYKD"));
engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

add the resource file in qrc file.
:/MyStyles/QtQuick/VirtualKeyboard/Styles/MYKD/style.qml

But, I get the error:
WARNING: Cannot find style "MYKD" - fallback: "default"

And I have test the qml file by. (QFileInfo::exists(QString(":/MyStyles/QtQuick/VirtualKeyboard/Styles/MYKD/style.qml")))

The file style.qml is exist.

Why I get the error? Is there any mistake in my code?

Thanks very much for help.

@bambooMZL not sure if something was changed with Qt 6.x, but here I described how I did it in a previous project:
https://forum.qt.io/topic/134990/customising-qt-virtual-keyboard-qml-for-a-cross-compiled-remote-device/3

Maybe this helps you...

@lemons Hello， Thanks very much for your help.

In Qt Version 6.4.1.
I have tried the method in post, https://forum.qt.io/topic/134990/customising-qt-virtual-keyboard-qml-for-a-cross-compiled-remote-device/3

I can change the keyboard layout.
But the style can't. The error is: WARNING: Cannot find style "MYKD" - fallback: "default"

Thanks.

@bambooMZL try to change the import path as below:

# engine.addImportPath((":/MyStyles"));
engine.addImportPath("qrc:/MyStyles");

@lemons
Hello.
I want to get the context of QML virtual keyboard, in main() function.
How can I get it?

For example, I can get the root context, by "engine.rootContext();"
But, how can I get the context of keyboard, "qtvirtualkeyboard"

Thanks very much.

I encountered the same problem at QT 6.4.3. And i found it is a bug in Qt 6.4. There are two workarounds to fix it if you don't want to upgrade QT version.

Please refer to https://bugreports.qt.io/browse/QTBUG-108536 for more details.
