Try this.
@
ListView {
id : view
....
....
....

MouseArea {
anchors.fill: parent
onClicked: {
console.log(" I am here"+currentIndex)
console.log(" My name is ="+view.model.get(currentIndex,"fileName"))
}

Hi Dheerendra..
Thanks for reply..
That doesnt work...

dheerendra

ListView has property called currentIndex. It works based on that. Here is complete example I tried on 3 platforms.

@ListView {
id : view
width: 200; height: 400

FolderListModel {
    id: folderModel
    nameFilters: ["*.qml"]
}

Component {
    id: fileDelegate
    Text { text: fileName }
}

model: folderModel
delegate: fileDelegate
    MouseArea {
        anchors.fill: parent
        onClicked: {
            console.log(" I am here"+currentIndex)
            console.log(" I am ok ="+view.model.get(currentIndex,"fileName"))
        }
    }

}

Hi
Thanks dheerendra..It works fine...but it does not work with currentIndex..It works with index.

And i found one more working.Here is the code..
@ MouseArea {
anchors.fill: parent
onClicked: {
xxx.text = folderList.folder + fileName
}
}@

Thanks

Good that it solved your issue. As side note, 'index' is visible inside the delegate. 'CurrentIndex' is inside the ListView. Since your mouseArea is inside the delegate, you need to use 'index' only. If your mouseArea is inside the View, you need to use 'currentIndex'.

Why do i get error "TypeError: Result of expression 'songView.model.get' [undefined] is not a function" when i use

@view.model.get(index,"fileName")@

Beemaneni.Can you please advice how you get the file name using code below.I get the file name but it also include the whole path leading to the files and the filename change when i just scrolling listview without selecting it.

@xxx.text = folderList.folder + fileName@

beemaneni

try with this
@ view.model.get(currentIndex,"fileName")@

If u dont mind post ur code ,let me have a look at that

Thanks
