C++/Qml communication and pageStack

[pixsta]

Hi,

I am using PageStackedWindow on Harmattan. Pages are dynamically loaded from qml files.
Now, I want to call a method from C++ within a loaded page, for instance function "dummyfnc":

import QtQuick 1.0
import Qt 4.7
import com.nokia.meego 1.0 
Page {
id: page1
function dummyfnc() {
// do something here
}
}

I tried something like this, but it does not work:

QObject *object = (QObject*)m_qmlView.rootObject()->findChild<QObject*>("page1");
// or
QObject *object = (QObject*)m_qmlView.rootObject()->findChild<QDeclarativeItem*>("pageStack")->findChild<QDeclarativeItem*>("page1");

QMetaObject::invokeMethod(object, "dummyfnc");

How can I correctly invoke the method?

Hi,

Here is the sample example using signal slots concept for invoking the QML functions. Hope this meets your requirement.

Thanks, but my problem is not the connection in general, but the connection to a page which is dynamically added to the page stack. As a workaround I am now using a cascade of signals and slots but that's not very convenient. It would be much nicer if I could directly get a pointer to the page from my C++ code.

Hi,
QML IDs are not the same thing than QObject name.
Set objectName property in your page1 and it will start to work.
