\title Qt Quick Controls 2 - Contact List
\ingroup qtquickcontrols2-examples
\brief A QML app using Qt Quick Controls 2 and a C++ class that implements
a simple contact list.
The \e {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.
\section1 C++ Backend
\borderedimage qtquickcontrols2-contactlist.png
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 \e MainForm.ui.qml. For more information about registering C++
classes as QML types, see \l {Defining QML Types from C++}.
\code
#include <QtQml/qqml.h>
...
qmlRegisterType<ContactModel>("Backend", 1, 0, "ContactModel");
...
\endcode
\section1 Designer Support
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 \e contactlist.pro.
\code
QML_DESIGNER_IMPORT_PATH=$$PWD/designer
\endcode
Because Qt Quick Designer cannot instantiate the ContactModel C++ class, we define
a mockup using a ListModel. This ensures that the ListView using the model shows something
in Qt Quick Designer.
