+ \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.
