Member Function Documentation

void sbIDeviceEventTarget::addEventListener

(

in sbIDeviceEventListener

aListener

)

Add a event listener

If the event listener is added while an event is being dispatched, the new listener will not be triggered until the next event is dispatched. (This is true even if the new event is dispatched before the current listener finishes; the new listener will see any nested events.)

boolean sbIDeviceEventTarget::dispatchEvent	(	in sbIDeviceEvent	aEvent,
		[optional] in PRBool	aAsync
	)

Dispatch a given event. The event will always be synchronously dispatched on the main (UI) thread.

An event may only be dispatched once; it may not be re-used.

Parameters

aEvent	the event to dispatch
aSync	dispatch the event asynchronously (default false)

Returns

Undefined if the event was dispatched asynchronously True if the event has been dispatched (false if no listeners)

void sbIDeviceEventTarget::removeEventListener

(

in sbIDeviceEventListener

aListener

)

Remove a event listener

If an event is currently being dispatched, the listener will not be triggered for the event if it has not already done so.
