Convert nested Qobject into python object

Acs Chris

Hey Guys

is there a way to convert a nested PySide6.QtCore.QObject to a regular python object.

currently I access each individuall proptery manually like

qobject.property(property_name)

thank you

@Acs-Chris What do you mean by "nested QObject" and why do you need to convert it to a Python object? You can use QObject instances in Python already.

@Acs-Chris said in Convert nested Qobject into python object:

a regular python object

As @jsulm has written. If you know that particular property is, say, a string you can always use str(qobject.property(property_name)), and you could wrap that it into a convenience Python function/method for re-use.

@jsulm with nested I mean that the Qobject has some props that are also qobject's or a QAbstractListModel

why I will do this let say a have a pseudo Qobject with like this

Qobject {
     property string foo: "foo"
     property string bar: "bar"
     property int mynumber: 12
     property Qobject baz: {
          property string name: "Name 1"
          property int age: 30 
          property Qobject bam: {
                property string hobby: "Tennis"
                property int days: 10 
                property QAbstractListModel players: listModel
          }
    }
}

of course I can grab each indivudal property but I was interested is there maybe a function or method to convert this into a regular python object or dict

@Acs-Chris
So this is a question about QML, which you did not mention before?

Acs Chris

@JonB the object comes from qml, that is true, but I think that is not importend because I am on python side and want to Improve handling the QObject.

Maybe it is more clear to add my code, as shown below I access each prop with the property method.
it was cool if there a way to convert the Qobject to Python Object todo such things like

source.id
source.boundingBoxes[0].x
source.boundingBoxes[0].y

source = data.property("source")
bounding_boxes = source.property("boundingBoxes")
boxes = []
for item in range(bounding_boxes.rowCount()):
    qbox = bounding_boxes.get(item)
    boxes.append(
        message_pb2.BoundingBox(
            id=int(qbox.property("id").toNumber()),
            name=qbox.property("name").toString(),
            x=int(qbox.property("x").toNumber()),
            y=int(qbox.property("y").toNumber()),
            h=int(qbox.property("h").toNumber()),
            w=int(qbox.property("w").toNumber()),
        )
    )

change_req = message_pb2.Camera(
    id=source.property("id").toString(),
    enabled=source.property("enabled").toBool(),
    name=source.property("name").toString(),
    addr=source.property("addr").toString(),
    path=source.property("path").toString(),
    username=source.property("username").toString(),
    password=source.property("password").toString(),
    transport=source.property("transport").toString(),
    port=int(source.property("port").toNumber()),
    http_port=int(source.property("httpPort").toNumber()),
    rotation=int(source.property("rotation").toNumber()),
    record=source.property("record").toBool(),
    motion_detection=source.property("motionDetection").toBool(),
    md_threshold=int(source.property("mdThreshold").toNumber()),
    md_min_area=int(source.property("mdMinArea").toNumber()),
    md_max_area=int(source.property("mdMaxArea").toNumber()),
    md_sensitivity=int(source.property("mdSensitivity").toNumber()),
    md_alerttime=int(source.property("mdAlerttime").toNumber()),
    md_use_max_min_filter=int(source.property("mdUseMaxMinFilter").toBool()),
    bounding_boxes=boxes,
)

@Acs-Chris
I believe you have to do it explicitly as you have done.
