How to access to a listview element

[mrdebug]

I need to get a variable status from each items in a listview.
My function is

            for (var count= 0; count< listViewModel.count; count++) {
                console.log(count, listView.contentItem.children[count])
            }

The output is

qml: 0 QQBlueBus_QMLTYPE_109(0x556e40f212a0)
qml: 1 QQBlueBus_QMLTYPE_109(0x556e40f0c4a0)

but it is happening something strange.
I can access at only 15 elements on my listview the others are undefined.
Where is the error?

@mrdebug said in How to access to a listview element:

listViewModel

what's in listViewModel
what model are you using
show us how you are creating/getting the data - have you proved what's in the container differs from your log? The locals and watches window should let you step through that.

Have you read? http://doc.qt.io/qt-5/qtquick-modelviewsdata-modelview.html#qml-data-models

That page has the following headings, and further links. Here's a quick summary but I suggest you expose yourself to that page above if you haven't already.

List Model http://doc.qt.io/qt-5/qml-qtqml-models-listmodel.html
XML Model http://doc.qt.io/qt-5/qml-qtquick-xmllistmodel-xmllistmodel.html
Object Model http://doc.qt.io/qt-5/qtquick-views-example.html#objectmodel
Integers as Models ie:

ListView {
       anchors.fill: parent
       model: 5
       delegate: itemDelegate
   }

This is my code:

                ScrollView {
                    id: scrollView1
                    anchors.fill: parent
                    ListView {
                        id: listView;
                        anchors.rightMargin: 1
                        anchors.leftMargin: 1
                        anchors.left: parent.left
                        anchors.bottom: parent.bottom
                        anchors.top: parent.top
                        spacing: 1
                        model: listViewModel;
                        delegate: listViewDelegate;
                    }
                }

                Component {
                    id: listViewDelegate;
                    QQAdc {
                        width: parent.width
                    }
                }

                ListModel {
                    id: listViewModel;
                }

to add element

listViewModel.append({sDescription: sDescription, sValue1: sValue1})

Now I need to get a property from each element.

Hi @mrdebug :)

try this : listViewModel.get(indexYouNeed).sValue1
