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
