Window.width in a property

Moisi

Hi,

I have a QtObject. This object is use like a model to stock informations used by my application. Among this informations, I want to have the width of the Window item.

But I'm not able to correctly stock the Window width in a property. When I try to read the property, I got the wrong value.

Here is my code:

Window
{
	visible: true
	width: 1300
	height: 800
	title: qsTr("Tests")

	Label { text: item.windowWidth; z: 5 }

	property var model: QtObject
	{
		id: item
		property int windowWidth: Window.width // 0
	}
}

Expected value from the windowWidth property: 1300
Current value: 0

I can't understant why I can't have the right value in my property... Did I miss some information about the Window item ?

Thank you ^^

u need to give an id to your Window item and then you can reach it by id

Wow, it works perfectly, thank you a lot ^^

Can I ask you why the id is mantatory ? Reading the Window Qml Type information, using Window.width should have work.

you need to give an id to your Window item and then you can reach it by id

Window {
    id:win

    visible: true
    width: 1300
    height: 480

    property var model: QtObject
        {
            id: item
            property int windowWidth: win.width // 0
        }


    Component.onCompleted: console.log(item.windowWidth)

}

@moisi
Window is the class name not he object itself,, you want to access a instance of it

Window {
  Rectangle{
    color : "red"
  }
  Rectangle{
    color : "blue"
 }

 Component.onCompleted : {
  // how to change  first rectangle color  ?  Rectangle.color ? but which rectangle ?
 // solution is to give id to you rectangle so you can cible it 
 }

}
