Program with qml in resource file don't open non-main qml files

[Harrix]

I installed Qt 5.0.1 for Windows 32-bit (MinGW 4.7, 823 MB)

Then I created simple Quick 2 application.
I have two simple qml files:
main.qml
@import QtQuick 2.0

Rectangle {
width: 360
height: 360
Text {
text: qsTr("Hello World")
anchors.centerIn: parent
}
MouseArea {
anchors.fill: parent
onClicked: {
Qt.quit();
}
}
HarrixMainButton{

}

}@

HarrixMainButton.qml
@import QtQuick 2.0

Item {
width: 93
height: 93

Rectangle {
    width: 50
    height: 62
    color: "red"
}

}@

And the program is working well. Then I put the qml files into the resource res.qrc in prefix qml and change main.cpp:

@#include <QtGui/QGuiApplication>
#include "qtquick2applicationviewer.h"
#include <QUrl>
#include <QDebug>
#include <QQmlContext>
#include <QQuickItem>

int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);

QtQuick2ApplicationViewer viewer;
//viewer.setMainQmlFile(QStringLiteral("qml/HarrixAI/main.qml"));
viewer.setSource(QUrl("qrc:qml/qml/HarrixAI/main.qml"));
viewer.showExpanded();

return app.exec();

}@

And the program does not work. The second file HarrixMainButton.qml is not loaded. Only the main first file main.qml is loaded.

@qrc:qml/qml/HarrixAI/main.qml:16:5: HarrixMainButton is not a type
Unable to find a renderable master window QtQuick2ApplicationViewer(0x28fe08) when trying to render QtQuick2ApplicationViewer(0x28fe08) ( QRect(8,30 116x0) ).@

How to fix the problem? In Qt 4.7 with Qt Quick 1.1 same method works.
