How to add private uri to QML Plugin

[shav]

Hi everyone!

I have a plugin for QML on C++. In this plugin I have a few classes which I want to use as a private in QML but don't want to share it to public users. I don't know any ways to create private QML types so I decide to create a special url. For example my plugins has a uri like:

com.company.sdk

and I've use it in QML like:

import com.company.sdk 1.0

But I want to create another uri for private classes something like this:

com.company.sdk.private

And than use it like:

import com.company.sdk.private 1.0

I try do this:

QString privateUri = QString("%1.private").arg(uri);
qmlRegisterSingletonType<MySingelton>(privateUri.toStdString().c_str(), 1, 0, "MySingelton", cache_manager_singletontype_provider);

But when I try to load my test application I received error:

QQmlApplicationEngine failed to load component
qrc:/main.qml:5 static plugin for module "com.company.sdk" with name "SDKPlugin" cannot be loaded: Cannot install singleton type 'MySingelton' into unregistered namespace 'com.company.sdk.private'

What I do wrong? How I can register a new namespace for my plugin? Is this possible?

• workaround A: register private types in initializeEngine() instead
• workaround B: remove the protected module identifier line from the qmldir file
