 /*!
+    \qmlproperty enumeration FolderListModel::status
+    \since 5.11
+
+    This property holds the status of folder reading.  It can be one of:
+    \list
+    \li FolderListModel.Null - no \a folder has been set
+    \li FolderListModel.Ready - the folder has been loaded
+    \li FolderListModel.Loading - the folder is currently being loaded
+    \endlist
+
+    Use this status to provide an update or respond to the status change in some way.
+    For example, you could:
+
+    \list
+    \li Trigger a state change:
+    \qml
+        State { name: 'loaded'; when: folderModel.status == FolderListModel.Ready }
+    \endqml
+
+    \li Implement an \c onStatusChanged signal handler:
+    \qml
+        FolderListModel {
+            id: folderModel
+            onStatusChanged: if (folderModel.status == FolderListModel.Ready) console.log('Loaded')
+        }
+    \endqml
+
+    \li Bind to the status value:
+    \qml
+        Text { text: folderModel.status == FolderListModel.Ready ? 'Loaded' : 'Not loaded' }
+    \endqml
+    \endlist
