Re: [Jython-users] Swing examples

[Jeff E. <je...@ad...>]

This works for me.  No explicit java.lang.Objects in sight.


from javax.swing import *

class PythonClass:
   pass

pythonInstance = PythonClass()
pythonString = 'foo'
pythonInt = 3

l = [pythonInstance, pythonString, pythonInt]

class MyModel(AbstractListModel):
   def getElementAt(self, i):
     return l[i]
   def getSize(self):
     return len(l)

model = MyModel()
jlist = JList(model)

frame = JFrame()
frame.contentPane.add(jlist)
frame.setSize(100,300)
frame.show()



Perhaps you should post an example that shows your problem.
