[SOLVED] One out of two Q_PROPERTY working

MaxL

Hi everyone,

I'm back with an other issue concerning Q_PROPERTY of one my object exposing another custom class that is not working properly.

Here is some code to understand what is going on :

-C++:
@
class My1stObject : public QObject
{
Q_OBJECT
Q_PROPERTY( QString name READ name() NOTIFY nameChanged )

public:

My1stObject( QObject* parent = nullPtr );

QString name(){ return _name; }
void setName( QString name ){ _name = name; emit( nameChanged() ); }

signals:
void nameChanged();
private:
QString _name;
}
@
@
class My2ndObject : public QObject
{
Q_OBJECT
Q_PROPERTY( int index READ index() NOTIFY indexChanged )
Q_PROPERTY( My1stObject* currentObject READ getCurrentObject NOTIFY currentObjectChanged )
public:

My2ndObject( QObject* parent = nullPtr );

int index(){ return _currentIndex; }
void setCurrentIndex( int index ){ _currentIndex = index; emit( indexChanged() ); }
My1stObject* getCurrentObject(){ return _currentObject ; }
void setCurrentObject( My1stObject* obj ){ _currentObject = obj; emit( currentObjectChanged ) ); }

signals:
void indexChanged();
void currentObjectChanged();
private:
int _currentIndex;
My1stObject* _currentObject;
}
@

Main:
@
QGuiApplication app( argc, argv );

qmlRegisterType< My1stObject >( "com.example", 1,0, "My1stObject" );
qmlRegisterType< My2ndObject >( "com.example", 1,0, "My2ndObject" );

My1stObject object1;
My2ndObject object2;

object1.setName( "MyTestObject" )
object2.setCurrentObject( &object1 );
object2.setCurrentIndex( 1 );

QQuickView myView;
myView.rootContext()->setContextProperty( "my2ndobject", &object2 );
myView.setSource( "qrc:/qml/Main.qml" );

myView.showFullScreen();
return app.exec();
@

Main.qml:

@
import com.example 1.0
Column
{
Text
{
property int currentIndex: my2ndobject.currentIndex
property My1stObject object1: my2ndobject.currentObject
text: currentIndex + " " + object1.name
}
Text
{
text: my2ndobject.currentIndex + " " +my2ndobject.currentObject.name
}
}
@

When running, it says that for the first Text, it cannot read property name of a null element while the second text perfectly show the object name. I have also tried with Binding but it does not change a thing. This behavior seems very strange to me because for currentIndex it works fine in both cases.

Any idea ?
Thanks

I have been looking for this for about an hour and four my problem, silly mistakes when registering types with copy/paste , both My1stObject and My2ndObject where registered with the same qmlName
