+    This handler is called when the mouse events are canceled, either because the event was not accepted or
+    another element stole the mouse event handling. This signal is for advanced users, it's useful in case there
+    is more than one mouse areas handling input, or when there is a mouse area inside a flickable. In the latter
+    case, if you do some logic on pressed and then start dragging, the flickable will steal the mouse handling
+    from the mouse area. In these cases, to reset the logic when there is no mouse handling anymore, you should
+    use onCanceled, in addition to onReleased.

+    property name is controlled by the value of \c WebView.windowObjectName 
+    attached property.
+
+    Exposing QML objects to a web page allows JavaScript executing in the web 
+    page itself to communicate with QML, by reading and writing properties and
+    by calling methods of the exposed QML objects.
+
+    This example shows how to call into a QML method using a window object.
