    <p>I have a little problem with ListModel and ListView, in particular concerning the move function of ListModel. I will show you code snippets from the DynamicList example included in the SDK with some modifications just to debug it: Code:</p> <pre><code> Item { property alias nameText: nameTextBox.text id: delegateItem width: listView.width; height: 55 clip: true Row { anchors.verticalCenter: parent.verticalCenter spacing: 10 Column { Image { source: "content/pics/arrow-up.png" MouseArea { anchors.fill: parent; onClicked: { var voice var nameInModel var nameInView voice = listView.contentItem.children[1] nameInModel = fruitModel.get(1).name nameInView = voice.nameText console.log("name before move in model at 1: "+nameInModel) console.log("name before move in list at 1: "+nameInView) fruitModel.move(index, index-1, 1) voice = listView.contentItem.children[1] nameInView = voice.nameText nameInModel = fruitModel.get(1).name console.log("name after move in model at 1: "+nameInModel) console.log("name after move in list at 1: "+nameInView) } } } .... </code></pre> <p>So, when the image "content/pics/arrow-up.png" is clicked, one item in the model is moved up by one position, now, in the example there are four items in order: "Apple"-"Banana"-"Cumqat"-"Durian" and this is the result of consol.log if I click "up" on the "Banana" moving that item to the first position:</p> <p>name before move in model at 1: Banana name before move in list at 1: Apple name after move in model at 1: Apple name after move in list at 1: Apple</p> <p>This is what happens if I click on Apple (that now is in the 2nd place) to moving it to the 1st position:</p> <p>name before move in model at 1: Apple name before move in list at 1: Apple name after move in model at 1: Banana name after move in list at 1: Apple</p> <p>So, first of all it is evident that the first index of ListModel is 0 while the first index of ListView is 1, then it is evident that items in the model have been moved but items in the list have not. Now, this is my problem: Imagine that "name" is the text of a TextEdit, so the the ListView delegate includes a TextEdit and it can be edited by the user. If I want to take that text I know that I can do this: Code:</p> <pre><code>for (var i = 0; i &lt;= myListView.count; i++){ myItem= myListView.contentItem.children[i] myName = myListView.name </code></pre> <p>But here is the problem, in my ListView there is also the possibility to move the items by using the move function of ListModel but if I move items and I use the previous cycle to take the "name" nothing seems to change (exactly as in the DynamicList example). On the other hand, if I take the "name" by using:</p> <pre><code> myName= myListModel.get(i).name </code></pre> <p>then, nothing seems to change when I modify the text in the TextEdit and I try to take the "name",</p> <p>So, what I have to do to obtain a ListView with TextEdit and with the possibility to move itemsof which I can record any changment?</p> <p>I hope I have been clear, Thank you very much, Giammarco </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
