I'm trying to use pyjamas (http://pyjs.org/) for the first time. My input
file, named hi.py, looks like this:
from pyjamas import Windowfrom pyjamas.ui import RootPanel, Buttonfrom
pyjamas.ui import HTML
def greet(sender):
Window.alert("Hello!")
b = Button("Click me", greet)RootPanel().add(b)
I run the following command:
python ~/pyjs-pyjs-07f54ad/bin/pyjsbuild hi.py
Building : hi
PYJSPATH : [
/Users/michaelnatkin/HelloPyjs
/Users/michaelnatkin/pyjs-pyjs-07f54ad/library
/Users/michaelnatkin/pyjs-pyjs-07f54ad/addons]Built to :
/Users/michaelnatkin/HelloPyjs/output
Which appears to run without errors, and here is my resulting directory:
Michael-Natkins-MacBook-Pro-2:HelloPyjs michaelnatkin$ ls .
hi.js hi.py outputMichael-Natkins-MacBook-Pro-2:HelloPyjs michaelnatkin$ ls
output
__init__.py gchart.gif hi.safari.cache.html
_pyjs.js hi.html history.html
bootstrap.js hi.ie6.cache.html tree_closed.gif
bootstrap_progress.js hi.mozilla.cache.html tree_open.gif
disclosurePanelClosed.png hi.nocache.html tree_white.gif
disclosurePanelClosed_rtl.png hi.oldmoz.cache.html
disclosurePanelOpen.png hi.opera.cache.html
I then direct my browser to one of the html files:
file:///Users/michaelnatkin/HelloPyjs/output/hi.html
and I get... a blank page. The only error in my js console is:
Uncaught SecurityError: Blocked a frame with origin "null" from accessing a
frame with origin "null". Protocols, domains, and ports must match.
which I guess isn't too surprising since the html file says:
<html><!-- auto-generated html - You should consider editing and adapting this
to suit your requirements. No doctype used here to force quirks mode; see
wiki for details: http://pyjs.org/wiki/csshellandhowtodealwithit/--><head>
<title>hi (Pyjamas Auto-Generated HTML file)</title><meta name="pygwt:module"
content="hi"></head><body style="background-color:white"><script
type="text/javascript" src="bootstrap.js"></script><iframe
id="__pygwt_historyFrame" style="display:none;"></iframe><script
type="text/javascript" src="bootstrap.js"></script><iframe
id="__pygwt_historyFrame" style="display:none;"></iframe></body></html>
So.. I'm completely stuck. Can someone tell me how to get this bad boy to
produce output? I've got a much more complicated app I want to create, but
if I can't say "Hello" it isn't going to go well. Thank you!
