+    \qmlproperty bool MouseArea::preventStealing
+    \since Quick 1.1
+    This property holds whether the mouse events may be stolen from this
+    MouseArea.
+
+    If a MouseArea is placed within an item that filters child mouse
+    events, such as Flickable, the mouse
+    events may be stolen from the MouseArea if a gesture is recognized
+    by the parent element, e.g. a flick gesture.  If preventStealing is
+    set to true, no element will steal the mouse events.
+
+    Note that setting preventStealing to true once an element has started
+    stealing events will have no effect until the next press event.
+
+    By default this property is false.
