Is it possible to get the reference count of a PyObject* object?

sys.getrefcount(object)

Note that this always returns one more than the actual value, as
there's always an additional ref when inside sys.getrefcount().

How can I make a tkinter window unsizeable?

Problem:

i have a very simple tkinter interface.  the code is more or less

#-----------------------
def MakeInterface():
    b = Pmw.ScrolledText(root, usehullsize=1, hull_width=400,
hull_height=300)
    b.pack(side=TOP, expand=0, padx=5, pady=5, anchor=S)


if __name__=='__main__':
    root = Tk()
    root.title('Title')
    MakeInterface()
    root.mainloop()

#------------------------

there are a few other things there, but not many.  how do i keep the 
user from resizing the window (minimizing i fine).

Solution:

Add

root.resizable(0,0)

after root = Tk().

That's from Fredrik Lundh's excellent An Introduction to Tkinter.
Specifically, the page at (wrapped for line length):

Is there a way to set a Tkinter window (Tk or Toplevel) to be at a certain position on the screen?

You can use the geometry method:

root=Tk()
root.geometry('100x100+20+20')

This makes root 100 pixels high and wide and positions it at 20,20
pixels on the screen.
