QML ComboBox get selected item from C++ [SOLVED]

[Folderol]

QT 5.1
So my problem is that i cannot get the selected item from an Combobox via C++.
The Combobox is created in QML.
@
ComboBox {
id: comboBoxObjekt;
objectName: "comboBoxObjekt";
activeFocusOnPress: true;
anchors.fill: parent;
model: m_Objekt;
}//ComboBoxObjekt
@

i can get my combobox like this.
@
item = this->View.rootObject()->findChild<QQuickItem*>( "comboBoxObjekt");
@

i can set items to my combobox like this.
@
this->current = this->View.rootContext();
//some code
this->current->setContextProperty("m_Objekt", QVariant::fromValue(dataList));
@

so when i try to get the selected item i use my
@
item = this->View.rootObject()->findChild<QQuickItem*>( "comboBoxObjekt");
@

to get the my combobox. then i connect my combobox like this

@
QObject::connect(CB,SIGNAL(currentIndexChanged()),this,SLOT(setupProject())); //Works

QObject::connect(CB,SIGNAL(currentIndexChanged(int)),this,SLOT(setupProject(int))); //Error
QObject::connect(CB,SIGNAL(currentIndexChanged(QString)),this,SLOT(setupProject(QString))); //Error
@
and i have read that you can use the signal currentIndexChanged(int) or (QString) to pass the current item as index = int or Text = QString? but because my CB is of QQuickItem i dont think thats possible? because when i try to use it i get these results.

No such signal ComboBox_QMLTYPE_26::currentIndexChanged(QString).
No such signal ComboBox_QMLTYPE_26::currentIndexChanged(int)

but if i use the one that work i can use the connect but i cant access the selected item?
So any idés of how i can access the current item from my combobox without creating a QCombobox in C++?

If i have misunderstood anything please enlighten me. Thanks in advance

[SOLVED]
CB->property("currentText").toString();
Got the current value from ComboBox with property currentText.
