qmlRegisterType dont' recogized into qml file

[elicat]

Hello,
Now i'm sudy use webengine (into ubuntu 32bit with QT 5.5)
i have declare in main.cpp

 qmlRegisterType<engineIndexHtml>("PageIndexHtml", 1, 0, "engineIndexHtml");

thi is a class qith file engineIndexHtml.h

class engineIndexHtml : public QObject
{
    Q_OBJECT
    Q_PROPERTY(int answerToLife READ answerToLife NOTIFY answerToLifeChanged)
public:
    explicit engineIndexHtml(QObject *parent = 0);
    int answerToLife() const;
    Q_INVOKABLE void changeAnswerToLife();
signals:
    void answerToLifeChanged(int answer);
private:
    int m_answerToLife;

};

and engineIndexHtml.cpp

#include "engineindexhtml.h"

engineIndexHtml::engineIndexHtml(QObject *parent)
    : QObject(parent),
      m_answerToLife(42)
{
}

int engineIndexHtml::answerToLife() const
{
    return m_answerToLife;
}
void engineIndexHtml::changeAnswerToLife()
{
    m_answerToLife = (int) (m_answerToLife * 8.5f) % 43;
    emit answerToLifeChanged(m_answerToLife);
}

After i want use object into QML file

. . . .
import PageIndexHtml 2.0

Window {
    engineIndexHtml {
        id: oldBeardedMan
        WebChannel.id: "wiseMan"
    }

Why QmlApplicationEngine don't load component and wirte this error ?

Cannot assign to non-existent property "engineIndexHtml"

The meaning of the message is clear but why? what is missing ?

@elicat said in qmlRegisterType dont' recogized into qml file:

qmlRegisterType<engineIndexHtml>("PageIndexHtml", 1, 0, "engineIndexHtml");

import PageIndexHtml 2.0

You declared it as a 1.0 version but imported a 2.0 version.

@elicat said in qmlRegisterType dont' recogized into qml file:

beside what @ambershark said, types always must start with a capital letter!

Additionally to the previous posters,

you need to register your types before creating the QQmlApplicationEngine object:

qmlRegisterType<YX>(....);

QQmlApplicationEngine engine;
engine.load(...);

@raven-worx I had forgotten the rule, thank you and the row of register it had been put before

 QQmlApplicationEngine engine;

Thanks
