![]() This is something that isn't usable by the view, but all your "first indentation" parents are children of the rootItem. Once registered, it can be created in qml as though it were a ListView or any other qml object. When your model is completed, you can assign it to your qml view in a few ways, registering it with qmlRegisterType is what I prefer ( ) Then as soon as its children are created, call parentTreeItem.appendChild(childTreeItem) That's where you'll want to parse through your wonderful dataset of 80's lyrics and assign each of them a TreeItem.Įach TreeItem (one for every row of data) should be given knowledge of its parent upon creation (in its constructor). The part you'll be particularly interested in is the implementation of the method setupModelData(). That example is working code, you can just copy and paste it and get a working model for your TreeView. This view model will flatten the parts of the tree model that at any point in time is visible inside view, to a list. An example GUI editor is included to demonstrate the model in action with XML and ASN.1 BER files. You'll want to (in C++) make a class for TreeItem, and a separate class for your TreeModel. TreeView uses a view model internally to convert a tree model into a model suited to be shown in a TableView. Qml Show Xml File In Treeview As Qabstractitemmodel. You can follow a fully implemented Qt example found here. Each TreeItem will have knowledge of their own children and their parent item. ![]() The view displays this like this file 1 calculation 1 calculation 2 file 2 -file 3 calculation 1 but for files and calculations, I use different delegates (using a Loader). The QStandardItemModel has different files on the first level, and each file can have several calculations as children. ![]() You'll want your "TreeModel" to be a collection of TreeItems. I have a QML TreeView which shows a QStandardItemModel. ![]() Your model doesn't have any parent child relationships which is why its displayed like a list. ![]()
