Solved:
[CPP]
for(int i=0; i<COUNT; i++) {
QString objName = QString("service%1").arg(i);
QObject *serviceObject =
objectHost->findChild<QObject*>(objName);
connect(serviceObject, SIGNAL(serviceIndicatorClicked(int)),
this, SLOT(serviceIndicatorClicked(int)));
}
[/CPP]

Hello,
can you give me an advice how I could connect signals by childs to
my C++-implementation?
I have following QML-structure:
[QML]
// Service.qml
Item {
id: service;
signal serviceIndicatorClicked(int index);
Rectangle {
id: serviceIndicator;
...
MouseArea {
anchors.fill: parent;
acceptedButtons: Qt.LeftButton;
onClicked: {
serviceIndicatorClicked(index);
}
}
}
}
// Host.qml
Rectangle {
id: hostItem;
Service {
...
}
}
[/QML]
I try to connect this signal with following lines:
[CPP]
connect(objectHost, SIGNAL(serviceIndicatorClicked(int)),
this, SLOT(serviceIndicatorClicked(int)));
[/CPP]
Then my result is:
[OUTPUT]
Object::connect: No such signal
Host_QMLTYPE_1::serviceIndicatorClicked(int)
Object::connect: (receiver name: 'MainWindow')
[/OUTPUT]
Of course, this makes sense to me, because the signal of the child
is not visible and not part of Host, right?
Is there an easy way to use this signal?
Cheers, Christian
