Hi,

Define a string type Qproperty in your cpp class and bind it to "source" property of Loader in QML.
Now you can change the source of that Loader by changing the QProperty value from cpp.

eg:- /// CPP code

class XXXXX /// Register this class/object to QML using qmlRegisterType()/setConextProperty()
{
Q_OBJECT
...
Q_PROPERTY(QString sourcePath READ sourcePath NOTIFY sourcePathChanged) //// Bind this "sourcePath" property to QML.

	QString sourcePath() { return m_SourcePath };

signals:
	 void sourcePathChanged(); /// Notify this signal when you change the source path from CPP
	 
private:
	 QString m_SourcePath; /// Update this value and emit sourcePathChanged() signal from cpp to reload QML Loader.

}

/// QML code

Loader {
id: myLoader
source: XXXXX.sourcePath /// Bind the property to loader's source property.
}

Hope this will help you.

Thanks,
