"""Event dispatch framework.
All objects that produce events in pyglet implement :py:class:`~pyglet.event.EventDispatcher`,
@ -44,155 +9,103 @@ Event types
For each event dispatcher there is a set of events that it dispatches; these
correspond with the type of event handlers you can attach. Event types are
identified by their name, for example, ''on_resize''.
If you are creating a new class which implements
:py:class:`~pyglet.event.EventDispatcher`, or want to add new events
to an existing dispatcher, you must call `EventDispatcher.register_event_type`
for each event type:
class MyDispatcher(pyglet.event.EventDispatcher):
# ...
MyDispatcher.register_event_type('on_resize')
identified by their name, for example, ''on_resize''. If you are creating a
new class which implements :py:class:`~pyglet.event.EventDispatcher`, you must call
`EventDispatcher.register_event_type` for each event type.
Attaching event handlers
========================
An event handler is simply a function or method, that is called when system or
program event happens. There are several ways to add a handler for an event.
An event handler is simply a function or method. You can attach an event
handler by setting the appropriate function on the instance::
When the dispatcher object is available as a global variable, it is convenient
to use the `event` decorator:
def on_resize(width, height):
# ...
dispatcher.on_resize = on_resize
@window.event
There is also a convenience decorator that reduces typing::
@dispatcher.event
def on_resize(width, height):
# ...
Here `window` is a variable containing an instance of `pyglet.window.Window`,
which inherits from `EventDispatcher` class. This decorator assumes that
the function is named after the event. To use the decorator with a function with
another name, pass the name of the event as the argument for the decorator:
You may prefer to subclass and override the event handlers instead::
@window.event('on_resize')
def my_resize_handler(width, height);
# ...
The most universal way to add an event handler is to call the `push_handlers`
method on the dispatcher object:
window.push_handlers(on_resize)
window.push_handlers(on_resize=my_handler)
window.push_handlers(on_resize=obj.my_handler)
window.push_handlers(obj)
This methods accepts both positional and keyword parameters. In case of keyword
arguments, the name of the event matches the name of the argument. Otherwise,
the name of the passed function or method is used as the event name.
If an object is passed as a positional argument, all its methods that match
the names of registered events are added as handlers. For example:
class MyDispatcher(pyglet.event.EventDispatcher):
# ...
MyDispatcher.register_event_type('on_resize')
MyDispatcher.register_event_type('on_keypress')
class Listener(object):
def on_resize(self, w, h):
# ...
def on_keypress(self, key):
# ...
def other_method(self):
# ...
dispatcher = MyDispatcher()
listener = Listener()
dispatcher.push_handlers(listener)
In this example both `listener.on_resize` and `listener.on_keypress` are
registered as handlers for respective events, but `listener.other_method` is
not affected, because it doesn't correspond to a registered event type.
Finally, yet another option is to subclass the dispatcher and override the event
handler methods::
class MyDispatcher(pyglet.event.EventDispatcher):
class MyDispatcher(DispatcherClass):
def on_resize(self, width, height):
# ...
If both a parent class and the child class have a handler for the same event,
only the child's version of the method is invoked. If both event handlers are
needed, the child's handler must explicitly call the parent's handler:
Event handler stack
===================
class ParentDispatcher(pyglet.event.EventDispatcher):
def on_resize(self, w, h);
# ...
When attaching an event handler to a dispatcher using the above methods, it
replaces any existing handler (causing the original handler to no longer be
called). Each dispatcher maintains a stack of event handlers, allowing you to
insert an event handler "above" the existing one rather than replacing it.
class ChildDispatcher(ParentDispatcher):
def on_resize(self, w, h):
super().on_resize(w, h)
# ...
There are two main use cases for "pushing" event handlers:
Multiple handlers for an event
==============================
* Temporarily intercepting the events coming from the dispatcher by pushing a
custom set of handlers onto the dispatcher, then later "popping" them all
off at once.
* Creating "chains" of event handlers, where the event propagates from the
top-most (most recently added) handler to the bottom, until a handler
takes care of it.
A single event can be handled by multiple handlers. The handlers are invoked in
the order opposite to the order of their registration. So, the handler
registered last will be the first to be invoke when the event is fired.
Use `EventDispatcher.push_handlers` to create a new level in the stack and
attach handlers to it. You can push several handlers at once::
An event handler can return the value `pyglet.event.EVENT_HANDLED` to prevent
running the subsequent handlers. Alternatively if the handle returns
`pyglet.event.EVENT_UNHANDLED` or doesn't return an explicit value, the next
event handler will be called (if there is one).
dispatcher.push_handlers(on_resize, on_key_press)
Stopping the event propagation is useful to prevent a single user action from
being handled by two unrelated systems. For instance, in game using WASD keys
for movement, should suppress movement when a chat window is opened: the
"keypress" event should be handled by the chat or by the character
movement system, but not both.
If your function handlers have different names to the events they handle, use
keyword arguments::
The order of execution of event handlers can be changed by assigning them
priority. Default priority for all handlers is 0. If handler needs to be run
before other handlers even though it was added early, it can be assigned
priority 1. Conversely, a handler added late can be assigned priority -1 to be
run late.
dispatcher.push_handlers(on_resize=my_resize, on_key_press=my_key_press)
Priority can be assigned by passing the `priority` named parameter to
`push_handlers` method:
After an event handler has processed an event, it is passed on to the
next-lowest event handler, unless the handler returns `EVENT_HANDLED`, which
prevents further propagation.
window.push_handlers(on_resize, priority=-1)
To remove all handlers on the top stack level, use
`EventDispatcher.pop_handlers`.
It can also be specified by using the `@priority` decorators on handler
functions and methods:
Note that any handlers pushed onto the stack have precedence over the
handlers set directly on the instance (for example, using the methods
described in the previous section), regardless of when they were set.
For example, handler ``foo`` is called before handler ``bar`` in the following
example::
@pyglet.event.priority(1)
def on_resize(w, h):
# ...
dispatcher.push_handlers(on_resize=foo)
dispatcher.on_resize = bar
class Listener(object):
@pyglet.event.priority(-1)
def on_resize(self, w, h):
# ...
listener = Listener()
Dispatching events
==================
dispatcher.push_handlers(on_resize, listener)
pyglet uses a single-threaded model for all application code. Event
handlers are only ever invoked as a result of calling
EventDispatcher.dispatch_events`.
Removing event handlers
=======================
It is up to the specific event dispatcher to queue relevant events until they
can be dispatched, at which point the handlers are called in the order the
events were originally generated.
In most cases it is not necessary to remove event handlers manually. When
the handler is an object method, the event dispatcher keeps only a weak
reference to it. It means, that the dispatcher will not prevent the object from
being deleted when it goes out of scope. In that case the handler will be
silently removed from the list of handlers.
This implies that your application runs with a main loop that continuously
updates the application state and checks for new events::
while True:
dispatcher.dispatch_events()
# ... additional per-frame processing
Not all event dispatchers require the call to ``dispatch_events``; check with
the particular class documentation.
.. note::
This means the following example will not work, because the pushed object
will fall out of scope and be collected::
In order to prevent issues with garbage collection, the
:py:class:`~pyglet.event.EventDispatcher` class only holds weak
references to pushed event handlers. That means the following example
will not work, because the pushed object will fall out of scope and be
collected::
dispatcher.push_handlers(MyHandlerClass())
@ -202,50 +115,12 @@ silently removed from the list of handlers.
my_handler_instance = MyHandlerClass()
dispatcher.push_handlers(my_handler_instance)
When explicit removal of handlers is required, the method `remove_handlers`
can be used. Its arguments are the same as the arguments of `push_handlers`:
dispatcher.remove_handlers(on_resize)
dispatcher.remove_handlers(on_resize=my_handler)
dispatcher.remove_handlers(on_resize=obj.my_handler)
dispatcher.remove_handlers(obj)
When an object is passed as a positional parameter to `remove_handlers`, all its
methods are removed from the handlers, regardless of their names.
Dispatching events
==================
pyglet uses a single-threaded model for all application code. Normally event
handlers are invoked while running an event loop by calling
pyglet.app.run()
or
event_loop = pyglet.app.EventLoop()
event_loop.run()
Application code can invoke events directly by calling the method
`dispatch_event` of `EventDispatcher`:
dispatcher.dispatch_event('on_resize', 640, 480)
The first argument of this method is the event name, that has to be previously
registered using `register_event_type` class method. The rest of the arguments
are pass to event handlers.
The handlers of an event fired by calling `dispatch_event` are called directly
from this method. If any of the handlers returns `EVENT_HANDLED`, then
`dispatch_event` also returns `EVENT_HANDLED` otherwise (or if there weren't
any handlers for a given event) it returns `EVENT_UNHANDLED`.
