Hi,

You already asked similar question. a lot of times. Modify the rowCount method and to return a valid number of rows.

CurrentIndex won't get updated automatically .To update the same index should be assigned to currentIndex onClicked event.

@Subuday said in Current Index always give 0:

When I click mentorsList.current index always gives 0.

As @SGaist already has told you, if you don't change currentIndex, his value will not change. And that is better!

You have to change you onClicked code as follow:

MouseArea {
    onClicked : {
        console.log("Clicked on item number " + index) //
        // select this item is ListView
        mentorsList.currentIndex = index
    }
}
