# Qt Quick Controls 1 - Text Editor Example

A QML app using Qt Quick Controls and a C++ class to provide a fully-functional rich-text editor application.

Warning: The Qt Quick Controls 1 module is deprecated since Qt 5.12. Use the latest Qt Quick Controls module instead.

The Text Editor Example presents a sample HTML file using the TextArea control, preserving the HTML formatting. It uses a C++ class to handle the document by providing options to open, format, and edit. The app also lets you open and edit a plain text files.

The C++ class, DocumentHandler, extends QObject and is registered as a QML type under the namespace, "`org.qtproject.example 1.0`".

The following snippets show how the type is registered under a namespace and later imported by main.qml.

QML type registration:

     #include <QtQml/qqml.h>
     ...
     qmlRegisterType<DocumentHandler>("org.qtproject.example", 1, 0, "DocumentHandler");
     ...

QML namespace import:

     import org.qtproject.example 1.0
