+    If the URL passed to QDeclarativeComponent is a network resource, or if the QML document references a
+    network resource, the QDeclarativeComponent has to fetch the network data before it is able to create
+    objects.  In this case, the QDeclarativeComponent will have a \l {QDeclarativeComponent::Loading}{Loading}
+    \l {QDeclarativeComponent::status()}{status}.  An application will have to wait until the component
+    is \l {QDeclarativeComponent::Ready}{Ready} before calling \l {QDeclarativeComponent::create()}.
+
+    The following example shows how to load a QML file from a network resource.  After creating
+    the QDeclarativeComponent, it tests whether the component is loading.  If it is, it connects to the
+    QDeclarativeComponent::statusChanged() signal and otherwise calls the \c {continueLoading()} method
+    directly. Note that QDeclarativeComponent::isLoading() may be false for a network component if the
+    component has been cached and is ready immediately.
