Hi,
I'm trying to walk the QML Object hierarchy from C++ to do some automatic
binding of UI elements to user generated projects. Since the QML elements
aren't created until they first become visible I'm trying to find a central
signal or virtual function I can use to catch new QML object being (delay)
created from the C++ side without having to create custom Component.onCompleted
signals all over the place in the QML.
For example below is a simple QML file, note that Label 2 on the second tab
isn't created until the user first opens that tab. Looking at the C++ code
below that, is there any way I can catch label2 being created from C++ in a
general way?
Cheers
Matt
import QtQuick 2.1
import QtQuick.Controls 1.0
TabView {
width: 300
height: 300
Tab {
title: "tab1"
Label {
id: label1
text: "tab1 text"
Component.onCompleted: {
console.log("tab 1 created")
}
}
}
Tab {
title: "tab2"
Label {
id: label2
text: "tab2 text"
Component.onCompleted: {
console.log("tab 2 created")
}
}
}
}
On the C++ side I have something like:
QQuickView* quickView = new QQuickView(QUrl::fromLocalFile("simple.qml"));
QQuickItem* root = quickView->rootObject();
// With root I can now walk the tree of QObjects and look at properties but
this won't include label2
// How can I add something here so I'm informed when an element like label2 is
actually created?
