Qt Quick Controls - Text Editor Example

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
