QML set tab property from outside

[haris123]

I need to set tabview tab item property from outside tab, but below giving me the error. where CustomItem is a custom qml component.

Rectangle {
        id: main_background

   TabView {
            id: setting_tab
  
            Tab {
                  CustomItem{
                     id: customId
                      indexofitem: -1
                  }
            }
}

//this function call from another qml
 function changeIndex(idx){
       customId.indexofitem = idx
 }
}

@haris123 If CustomItem is the only child inside Tab then a simple way:

setting_tab.getTab(0).children[0].indexofitem
