2 Dimensional array in QML

[nestuser]

Hi,
I want to send a signal with an array argument from QML to CPP. I did it using 1 dimensional array.
my sample code is

Rectangle {
 
    width: 400
    height: 400
    color: "#d5b9b9"
    id:rect
    property variant signalStrings: []
    signal handledSignal(variant array)
}

Rectangle {

    width: 400
    height: 400
    color: "#d5b9b9"
    id:rect
    property variant signalStrings: []
    signal handledSignal(variant array)
}

To copy to clipboard, switch view to plain text mode 

var temp = rect.signalStrings
        temp[temp.length] = "onSignal_object1"
        temp[temp.length] = "onSignal_object2"
        temp[temp.length] = "onSignal_object3"
        temp[temp.length] = "onSignal_object4"
        rect.signalStrings = temp
        rect.handledSignal(signalStrings)

var temp = rect.signalStrings
        temp[temp.length] = "onSignal_object1"
        temp[temp.length] = "onSignal_object2"
        temp[temp.length] = "onSignal_object3"
        temp[temp.length] = "onSignal_object4"
        rect.signalStrings = temp
        rect.handledSignal(signalStrings)

To copy to clipboard, switch view to plain text mode 

Now I want to send a two dimensional array. How can I do it?

Thanks in advance....

There is no such thing as a two dimensional array in C++ (nor in JavaScript/QML).

Ok, thank you..
Can I do it as a list of variant property?
What I tried is

property variant signalStrings: {'signal':"",'CAN':"",'PGN':"",'Bitpos':""}
property list<signalStrings>signalList:[signalStrings{signal:"ss";CAN:"aa";PGN:"jjj";Bitpos:"ww"}]

property variant signalStrings: {'signal':"",'CAN':"",'PGN':"",'Bitpos':""}
property list<signalStrings>signalList:[signalStrings{signal:"ss";CAN:"aa";PGN:"jjj";Bitpos:"ww"}]

To copy to clipboard, switch view to plain text mode 

but it causes some errors.. (signalStrings is not a valid property type)
Please suggest a suitable way...

Thanks in advance......

As I said, there is no such thing as a two dimensional array. You are still dealing with a one dimensional array so you can do it exactly the same way as before. Only that an element of each array is another array.
