The following example shows how to create a model from C++ with multiple columns:Īnchors. Since Qt 5. To create models with multiple columns, either use TableModel or a C++ model that inherits QAbstractItemModel. This informs TableView that it needs to use the provider functions again to recalculate and update the layout.

Let's say you are going to use TableView to show some data. Actual implementation will hardly depend on your requirements, but here is an example of how it could be done. It all is available in Qt 5.15 (use online installer ). But to have everything you want you need to include Qt.labs.qmlmodels. As soon as you flick, new rows and columns enter the viewport, while old ones exit and are removed from the viewport. Since Qt 5.12 you can use TableView QML type. ![]() This means that while the model can have any number of rows and columns, only a subsection of the table is usually visible inside the viewport. ![]() The classes in the Qt QML module enable QML objects to be loaded and manipulated from C++, and the nature of QML engines integration with Qts meta object system enables C++ functionality to be invoked directly from QML. List of all members, including inherited membersĪ TableView has a model that defines the data to be displayed, and a delegate that defines how the data should be displayed. QML is designed to be easily extensible through C++ code.
