Daily Python-URL: Python port of SWT?

Scott Sanders (dotnot) asks: Is anyone working on a port of SWT to Python? Is anyone interested in such a thing?

Of course this is something that is possible today using Jython.  I have configured the RedRobin Jython Eclipse plugin to allow me to easily script SWT (and JFace from Jython ... works like a charm.)  Here is a quick Jython Hello World for SWT.

from org.eclipse.jface.window import *
from org.eclipse.swt import *
from org.eclipse.swt.widgets import *
import sys

class Hello(ApplicationWindow):
  def createContents(self, parent):
  b = Button(parent, SWT.PUSH, widgetSelected=self.helloWorld)
  b.text = "Hello World"
  return b    

  def helloWorld(self, evt):
     print "Hello There ..." 
     sys.exit(0)        
 
w = Hello(None)
w.blockOnOpen = 1
w.open()
Display.getCurrent().dispose()

In order to get this to work in eclipse using the Jython plugin, you need to either create a jython project in eclipse or add the Jython nature to an existing project, add the swt and jface jars into the class path in the project's jython properties and finally set the java.library.path to the location of the swt library also in the project's jython  properties.  This last step is so that swt can find its os native libraries. 

Brian Zimmer's 'An Introduction to Jython' presentation

Brian Zimmer presented Jython to the Chicago Python Users Group (chipy). Here is a link to his slides.

Use Jython to time Java code

Here is an interesting Jython receipe - Use Jython to time Java code   A clever way to do some low level timing of java functions, all from Jython. 

Updated Jython Bibliography

I've updated the Jython Bibliography, adding a few new articles and some older ones that were missed before. Please let me know if I've missed any!

Inline Java code into Jython

This recipe shows how to insert java code into a jython program. The java code is automatically compiled and the resulting class is imported and returned. Compilation only occurs after a change of the java source.

Moving Jython Forward: PSF Grant!

Jython has recieved a grant injection from the PSF!  One of the three selected grant proposals deals specifically with revitalizing Jython development and Brian Zimmer will manage the project now called: Moving Jython Forward.
