![]() qmlproperty QAbstractItemModel TreeView :: model. Add the modules path to the QMLIMPORTPATH. A TreeView implements a tree representation of items from a model. Ism.select(ix, ItemSelectionModel.Select)įor(var i=0 i < tree_model. Copy the modules folder to your project, then add the qmltreeview.pri file or manually add headers, source and resource file. Models still use ListModel objects, just make them. Note that the ExpandItem action does not move the cursor. Qml does not provide tree controls, so I can only write it myself. It is simple to construct a tree view displaying data from a model. QTreeView implements the interfaces defined by the QAbstractItemView class to allow it to display data provided by models derived from the QAbstractItemModel class. Var ix1 = tree_model.index(0, 0, treeView.rootIndex) The result is the same as if you would click the + of a collapsed tree view node. The QTreeView class is one of the Model/View Classes and is part of Qt's model/view framework. SelectionMode: SelectionMode.MultiSelection Item1->appendRows() Įngine.rootContext()->setContextProperty("tree_model", &model) Įngine.load(QUrl(QStringLiteral("qrc:/main.qml"))) QStandardItem *item1 = new QStandardItem("file1") QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling) Note that to just implement the model and view, I've used no Desktop Components. This article will teach you one of the ways in which you could do it. To obtain the child you must first have the parent, so in the case of your scheme you must obtain "file1" and for this you must obtain his parent, and this parent is the rootIndex of the TreeView, so the sequence is: rootIndex -> file1 -> task1. QML TreeModel and TreeView implementation with ListModel and ListView Introduction There seems to be a pressing need for some quick implementation of TreeView and model in QML. ![]()
