interface nsIEventTarget : nsISupports

Constants

 This flag specifies the default mode of event dispatch, whereby the event
 is simply queued for later processing.  When this flag is specified,
 dispatch returns immediately after the event is queued.
const unsigned long DISPATCH_NORMAL = 0
 This flag specifies the synchronous mode of event dispatch, in which the
 dispatch method does not return until the event has been processed.

 NOTE: passing this flag to dispatch may have the side-effect of causing
 other events on the current thread to be processed while waiting for the
 given event to be processed.
const unsigned long DISPATCH_SYNC = 1

Methods

 Dispatch an event to this event target.  This function may be called from
 any thread, and it may be called re-entrantly.

 @param event
   The event to dispatch.
 @param flags
   The flags modifying event dispatch.  The flags are described in detail
   below.
 
 @throws NS_ERROR_INVALID_ARG
   Indicates that event is null.
 @throws NS_ERROR_UNEXPECTED
   Indicates that the thread is shutting down and has finished processing
 events, so this event would never run and has not been dispatched. 
void dispatch(in nsIRunnable event, in unsigned long flags)
 Check to see if this event target is associated with the current thread.

 @returns
   A boolean value that if "true" indicates that events dispatched to this
   event target will run on the current thread (i.e., the thread calling
   this method).
