Kamaelia.UI.Pygame.EventHandler

Pygame event handling {#364}

A simple framework for handling pygame events. Reimplement the appropriate stub method to handle a given event.

Example Usage {#365}

Detecting key presses and mouse button depressions and releases::
class MyEventHandler(EventHandler):
def __init__(self, target):
super(MyEventHandler,self).__init__() self.target = target
def keydown(self, key, mod, where):
print "Keypress '"+key+"' detected by "+where
def mousebuttondown(self, pos, button, where):
print "Mouse button depressed"
def mousebuttonup(self, pos, button, where):
print "Mouse button released"

How does it work? {#366}

Implement your event handler by subclassing EventHandler and reimplementing the stub methods for the particular events you wish to handle.

The code that reads the events from pygame should pass them one at a time to EventHandler by calling the dispatch(...) method.

The optional 'trace' argument to the initialiser, when non-zero, causes the existing stub handlers to print messages to standard out, notifying you that the given event has taken place.
