how to detect if all child items have focus set to "false" within an item?

[AYYAPPA]

i have a parent qml called ,

Rectangle
{
id: main
Item
{
id: item1
}
Item
{
id: item2
}
Item
{
focus: true
id: item3
}
}

item1 and item2 contains TextField as child item which receives focus on clicking the item.
when i launch for first time item3 has focus set to true , but when i click any other item1 or itme2 it looses focus as text field inside item2 or item3 takes the focus.
now when i close item2 or item3 their children loose focus. at this moment none of the items have focus. so i would want to go set item3 focus to true .
so basically i want to know when none of the child items in "main" rectangle have focus so that i can set "item3" focus true.

Hi @AYYAPPA

this should work.

Rectangle
{
    property bool noActiveFocus: !item1.activeFocus && !item2.activeFocus && !item3.activeFocus
    onNoActiveFocusChanged: if(noActiveFocus) item3.focus = true

    id: main
    Item{
         id: item1
    }

    Item{
        id: item2
    }

    Item{
        focus: true
        id: item3
   }
}
