Is it possible to make a Connections in a QmlTimer component ?

[Moisi]

Hi,

I'm trying to connect a signal from an Item to a Timer using Connections.

My code fails when I try to run it with the following error PathToMyProject/main.qml:21 Cannot assign to non-existent default property

If I replace the Timer component by an Item component everything works fine.

Here is my code:

import QtQuick 2.12
import QtQuick.Controls 2.5
import QtQuick.Window 2.2
import QtQml 2.12


ApplicationWindow{
	id: root
	width: 500
	height: 500
	visible: true

	Item {
		id: itemId
		signal mySignal()
	}

	Timer { // Replacing the Timer component by an Item component does not trigger any error
		id: timerId
		property int nbr: 13
		Connections // This is the line 21
		{
			target: itemId
			onMySignal: timerId.nbr = 42;
		}
	}

	Column {
		Button { text: "emit signal"; onClicked: itemId.mySignal(); }
		Button { text: "display nbr"; onClicked: console.log(timerId.nbr); }
	}
}

It's like it is not possible to assign a Connections to a Timer component.

Can someone explain me if I'm right and why ?

Thank's a lot ^^

Don't define the Connections inside the Timer.

Timer {
 d: timerId
 property int nbr: 13
	}

Connections {
 target: itemId
 onMySignal: timerId.nbr = 42;
	}

In this context you don't even need Connections

Item {
 id: itemId
 signal mySignal()
 onMySignal : timerId.nbr = 42;
}

Hi,

Thank you for your answer.

Yes, this is a solution. ^^

But I'm still curious about the reason why I can not define the Connections inside the Timer.
