Example Usage

::

class SimpleApp1(PyGameApp):

def initialiseComponent(self):

self.addHandler(MOUSEBUTTONDOWN, lambda event : self.mousedown(event))

def mainLoop(self):

... draw and do other stuff here... return 1

def mousedown(self, event):

print "Mouse down!"

app = SimpleApp1( (800,600) ).run()

How does it work?

Subclass this component to implement your own pygame 'app'. Replace the mainLoop() stub with your own code to redraw the display surface etc. This method will be called every cycle - do not incorporate your own loop!

The self.screen attribute is the pygame surface you should render to.

The component provides a simple event dispatch framework. Call addHandler and removeHandler to register and deregister handlers from events.

More than one handler can be registered for a given event. They are called in the order in which they were registered. If a handler returns True then the event is 'claimed' and no further handlers will be called.

The component will terminate if the user clicks the close button on the pygame display window, however your mainLoop() method will not be notified, and there is no specific 'quit' event handler.

class PyGameApp(Axon.Component.component)

PyGameApp(screensize[,caption][,transparency][,position]) -> new PyGameApp component.

Creates a PyGameApp component that obtains a pygame display surface and provides an internal pygame event dispatch mechanism.

Subclass to implement your own pygame "app".

Keyword arguments:

• screensize -- (width,height) of the display area (default = (800,600))
• caption -- Caption for the pygame window (default = "Topology Viewer")
• fullscreen -- True to start up in fullscreen mode (default = False)
• transparency -- None, or (r,g,b) colour to make transparent
• position -- None, or (left,top) position for surface within pygame window
