Event
MouseEvent
readonly long detail
A numeric detail about the event. For click, mousedown, and mouseup events (see "MouseEvent"), this field is the click count: 1 for a single-click, 2 for a double-click, 3 for a triple-click, and so on. For DOMActivate events, this field is 1 for a normal activation or 2 for a "hyperactivation," such as a double-click or
Shift-Enter combination.
readonly
AbstractView
view
The window (the "view") in which the event was generated.
initUIEvent( )
Initializes the properties of a newly created UIEvent object, including the properties inherited from the Event interface.
The UIEvent interface is a subinterface of Event and defines the type of Event object passed to events of type DOMFocusIn, DOMFocusOut, and DOMActivate. These event types are not commonly used in web browsers, and what is more important about the UIEvent interface is that it is the parent interface of MouseEvent.
