Enumerate QML properties in Qt C++?
-
Greetinsg all,
Im doing the following to render a QML in my Qt embedded app:
@
QDeclarativeView *view = new QDeclarativeView(this);
view->setSource(QUrl::fromLocalFile("dial.qml"));
view->show();
QObject *dial = view->rootObject();
@Is there a way i can enumerate all the property values defined in the root item?
For example, if i have the QML:
@
import QtQuick 1.0
Item {
id: root
property real dial_value : 0
property real dial_length: 0
property real background_opacity: 1
etc, etc
}
@Is there a Qt method that will end up with me having a list of these strings:
@
dial_value
dial_length
background_opacity
@Ive tried, the following, but it the list is empty:
@
QList<QByteArray> list = dial->dynamicPropertyNames();
@Thanks in advance!

The "rootObject()" is not your "root" item!
Best way (in my opinion) is to add objectName to your root object:
@
Item {
objectName: "myRoot"
id: root
...
}
@Then, in C++, you can get that object using QObject::findChildren() or findChild():
@
QObject *dial = view->finChild<QObject *>("myRoot");
@Then you can iterate over every property that object has using QObject::metaObject().
