Communication between Qml Objects

[Bhushan_Sure]

how to communicate between 2 qml objects, without defining qml object into other one.
Like

One.qml
{
}

Two.qml
{
}

I want to send signal from one.qml to two.qml so that i can perform some actions in two.qml on the basis of some actions in one.qml.

i dont want to define one.qml in two.qml.
is there any way ?

hi @Bhushan_Sure

if you gives the qml object an Id, you can access them that way

One.qml
{
id: one
onMySignal: two.callFunction()//for example
}
Two.qml
{
id:two
}

Yes.

One{
id:o
}
Two{
id:t
}
Component.onCompleted : { o.signalName.connect(t.functionName) }

or

One{
id:o
onSignalName : { t.functionNAme()}
}
Two{
id:t
}

@J.Hilk where do i have to define Mysignal ?

[J.Hilk]

@Bhushan_Sure
inside One.qml

signal mySignal()

[Bhushan_Sure]

@J.Hilk @LeLev Ok i will try both the way.

@Bhushan_Sure I also use this method:
Let say you wanna open other window when clicked:

onClicked{
var component = Qt.createComponent("two.qml")
var window = component.createObject('oneqml mainscope id')
window.show()
}

@J.Hilk
@LeLev
@Yunus

oneqml.qml

Rectangle{
    id:one
    height: 400
    width: 400
    color: "red"
    signal mysignal

    MouseArea {
        anchors.fill: parent
        onClicked: {
            mysignal()
        }
    }
    onMysignal:{
     two.bhushan()
    }
}

twoqml.qml

Rectangle
{
    id:two
    height: 400
    width: 400
    color: "yellow"

    function bhushan()
    {
        console.log("Bhushan")
    }
}

error is two is not defined
What i have done wrong ?

onMysignal

the reaction to mySignal needs to be inside the parent - where you instantiate One.qml object

[Bhushan_Sure]

@J.Hilk
@LeLev
@Yunus

That worked !!
But i don't want to instantiate one.qml into two.qml because
whatever there in one.qml that will come in two.qml.

Like one rectangle come into two.qml ! you got ?

you don't have to .. see my first compment

//main.qml

...
One{
id:o
onSignalName : { t.functionNAme()}
}
Two{
id:t
}
...

[Yunus]

@Bhushan_Sure Okey you only need that function do this exactly:(Two 's 't' should be upper case be careful. You also needto recreate your two.qml file as Two.qml

//oneqml

//up the mousearea
Two{
id:caller
}

onClicked{
caller.bhushan()
}

@Yunus @J-Hilk @LeLev It solved my problem, Thank you :)
