[pygtk] TypeError: enter() takes no arguments (1 given)

[Peter E Dennis]

Hi All,

This is my first time posting (actually second - I foolishly attached
the glade file to first post and got rejected).

I have the following program:

#!/usr/bin/env python

import sys
try:
   import pygtk
   pygtk.require('2.0')
except:
   pass
try:
   import gtk
   import gtk.glade
except:
   sys.exit(1)


class MainWindow:

   def __init__(self):

       # Set the Glade file
       self.gladefile = "sscce.glade"
       self.wTree = gtk.glade.XML(self.gladefile)

       # Get the Main Window, and connect the "destroy" event
       self.window = self.wTree.get_widget("window1")
       if (self.window):
           self.window.connect("destroy", gtk.main_quit)

       # Get the status bar and display info to user when entered
       self.statusbar1 = self.wTree.get_widget("statusbar1")

       self.button1 = self.wTree.get_widget("button1")
       if (self.button1):
           self.button1.connect("enter", self.button1.enter)
           self.statusbar1.push(1, "Button entered")

   def main(self):
       gtk.main()


if __name__ == "__main__":
   mw = MainWindow();
   gtk.main()

At the moment I'm trying to learn how to use the gtk.Button.enter method.

However when I launch my script/app and each time I move the mouse
pointer over the button, I get the error as shown in the subject and
below:
$ ./main.py
TypeError: enter() takes no arguments (1 given)
TypeError: enter() takes no arguments (1 given)
TypeError: enter() takes no arguments (1 given)

I don't really understand this error as it appears (to me) that I'm
actually giving 0 arguments to the method 'self.button1.enter'

Could someone please explain (I feel like Pauline Hanson) why the
error mentions one argument given and what I can do to fix it?

Also if anyone has the time it would be great to see how I can then
display a message in the status bar, at the moment the message appears
when I first launch the app, so no idea if it is actually working
during the mouse over or not.

Many thanks,

Peter.
