[Jython-users] Parameters to actionPerformed?

[<pi...@hu...>]

Any thougts on the best way to bind events?

I'm working with a form that has two text fields and a button; eventually 
it's going to be a login form.  For the button I'm using:

btnLogin = java.awt.Button("Login", actionPerformed=processLogin(txtLoginID.text,
 txtPasswd.txt))

When I have any type of parameters for processLogin it dies on me with (I 
didn't paste the entire traceback): 

  java.lang.ArrayIndexOutOfBoundsException

If I place 'actionPerformed=processLogin("test")' it prints out "test" when 
the program starts and does nothing when the button is pressed.  When I 
place 'processLogin' by itself the method is invoded, however it has no 
way of knowing about the values in the login method (where the form is created).

I have some buttons and menu items on other forms that don't need to pass 
parameters and they work fine.  Does anyone know of a better way to pass 
this information?

Thanks for any help,

Inherits from awt.Event.ActionListener in your class and implement the
actionPerformed method... like...

from java.awt import *
from java.awt.event import *

class LogonForm(ActionListener):

    def __init__(self):
        self.btnLogin = Button("Login")
        self.txtLoginID = TextField()
        self.txtPasswd = TextField()

        ..... (implenent the GUI, etc...) 

    def actionPerformed(self, event):
        source = event.getSource()
        if source==self.Login:
            self.processLogin(self.txtLoginID.text, self.txtPasswd.text)
        else:
             #handle some other event...

    def processLogin(loginID, passwd):
        #do something...


Hope that helps.
