TypeError: startView() takes exactly 1 argument (3 given)

[Ron Croonenberg]

Hello,

I am trying to write a plugin for Rhythmbox in python and run into a 
'strange' problem. For a method (an action for clicking a button) I 
started a method and however many arguments I use, it keeps giving me 
the same error:

'TypeError: startView() takes exactly 1 argument (3 given)'

does someone have any pointers or tips?, thanks;

Ron

here is the code I have the problem with:

import rb
import pygtk
import gtk, gobject


pygtk.require('2.0')



class tb_button (rb.Plugin):

#
# the init thing
#
    def __init__(self):
       rb.Plugin.__init__(self)

#
# the activate thing
#
    def activate(self, shell):
       self.shell = shell

       view_button = """
                   <ui>
                     <toolbar name="ToolBar">
                       <placeholder name="View">
                         <toolitem name="View" action="viewAction">
                         </toolitem>
                       </placeholder>
                     </toolbar>
                   </ui>
                   """

       # create a new action
       action = gtk.Action('viewAction',
                         _(' _View'),
                         _('Browse Track '), "")

       # connect it
       action.connect('activate', self.startView, shell)
       action_group = gtk.ActionGroup('NewActionGroup')
       action_group.add_action(action)
       shell.get_ui_manager().insert_action_group(action_group)

       # add it to the toolbar
       ui_manager = shell.get_ui_manager()
       ui_manager.add_ui_from_string(view_button)



#
# Start the  View

    def startView(self, widget, shell, se):
# nothing yet
       return
