[Jython-users] A Little Java2D toolkit

[Zhong Wenstone-a. <a1...@mo...>]

Hi,
	Scratching Frame,Panels to test a java2d code snippet
is always  boring. I use a little toolkit wrote in Jython to help on this,
Get visual feedback immediately. 

To use it:
Jython 2.1 on java1.4.1_02 (JIT: null)
Type "copyright", "credits" or "license" for more information.
>>> from prac2d import *
>>> start()
>>> g2d.drawString("Test",0,0)
>>> g2d.drawString("Test",10,10)
>>>

	def addComp(self,jCom):
		self.getContentPane().add(jCom)

jf = MyFrame("Prac 2d")
jp = Panel()
jf.addComp(jp)
g2d = bi.createGraphics()

	while 1:
		time.sleep(0.05)
		jf.repaint()
