Qt Quick Controls 2 - Contact List
The Contact List Example shows how to integrate a C++ backend in a way that is compatible with Qt Quick Designer. For the declarative parts of the UI, .ui.qml files are used that can be edited visually in the Qt Quick Designer.
The contact list application allows the user to add, edit, and remove contacts. The actual implementation is done in C++ and exposed as a QAbstractListModel.
The ContactModel C++ class is registered under a namespace and later imported and instantiated by MainForm.ui.qml. For more information about registering C++ classes as QML types, see Defining QML Types from C++.
#include <QtQml/qqml.h> ... qmlRegisterType<ContactModel>("Backend", 1, 0, "ContactModel"); ...
In the designer subdirectory, we create a plugin that replaces the ContactModel in Qt Quick Designer. For this to work we add the following line to contactlist.pro.
