/**
|
||||
* The input handler is an arbiter between the Fennec chrome window inputs and any
|
||||
* registered input modules. It keeps an array of input module objects. Incoming
|
||||
* input events are wrapped in an EventInfo object and passed down to the input modules
|
||||
* in the order of the modules array.
|
||||
*
|
||||
* Input modules must provide the following interface:
|
||||
*
|
||||
* handleEvent(evInfo)
|
||||
* Entry point by which InputHandler passes wrapped Fennec chrome window events
|
||||
* to the module.
|
||||
*
|
||||
* cancelPending()
|
||||
* Called by the InputHandler as a hint to the module that it may wish to reset
|
||||
* whatever state it might have entered by processing events thus far. For
|
||||
* instance, a module may have grabbed (cf grab()) focus, in which case the
|
||||
* InputHandler will call cancelPending() on all remaining modules.
|
||||
*
|
||||
*
|
||||
*
|
||||
* An input module may wish to grab event focus of the InputHandler, which means that it
|
||||
* wants to process all incoming events for a while. When the InputHandler is grabbed
|
||||
* by one of its modules, only that module will receive incoming events until it ungrabs
|
||||
* the InputHandler. No other modules' handleEvent() function will be called while the
|
||||
* InputHandler is grabbed. Grabs and ungrabs of the InputHandler require an object reference
|
||||
* corresponding to the grabbing object. That is, a module must call inputHandler.grab(this)
|
||||
* and .ungrab(this) in order for the calls to succeed. The object given as the argument
|
||||
* will be that which is given event focus. grab/ungrab may be nested (that is, a module can
|
||||
* grab as many times as it wants to) provided that they are one-to-one. That is, if a
|
||||
* module grabs four times, it should be sure to ungrab that many times as well. Lastly,
|
||||
* an input module may, in ungrabbing, provide an array of queued EventInfo objects, each of
|
||||
* which will be passed by the InputHandler to each of the subsequent modules ("subsequent"
|
||||
* as in "next in the ordering within the modules array") via handleEvent(). This can be
|
||||
* thought of as the module's way of saying "sorry for grabbing focus, here's everything I
|
||||
* kept you from processing this whole time" to the modules of lower priority. To prevent
|
||||
* infinite loops, this event queue is only passed to lower-priority modules.
