P2: Important Description
After the Set visibility to 'on' by default change in QSR-1057, the examples have redundant code that is no longer needed.
Main.cpp file code part can be removed.
for (SafeRenderer::quint32 i=0U;i<layout.count(); i++) {
QSafeEventVisibility visible;
visible.setId(layout.item(i).id());
visible.setValue(1U);
stateManager.handleEvent(visible);
}
