Pack parent control in child using control.pack(in_= syntax?

I've a parent class the generates a menu as in: = Menubutton(self.main, relief=RAISED, width=20,
bd=0, bg='#ECECEC')

I can then pack this menu ( into the current parent
window/frame and it appears as expected.

However, if I call another class - tool_panel(self) and then try to
post the tm menu into a frame (tf) using
pack(in_=tf, side=RIGHT, anchor=NE)
- the menu takes up space, but doesn't appear. I can see this because
when I pack the icon logo without the menu, the logo is centered in
the new frame. With the menu included, the icon logo is shifted left.

Thoughts or guidance will be greatly appreciated.



Here's my menu creation code in the parent class: = Menubutton(relief='raised', width=20,
bd=0, bg='#ECECEC') = Menu(, tearoff=0,
title='Tool Option')['menu'] =

I set up the call to the tool_panel with a call:

self.tool_panel = tool_panel(self)

Here's the actual tool_panel that I wish to pack into (imported from
another source file called with 'from panels import *'):

class tool_panel(panel):

def __init__(self, parent):
panel.__init__(self, parent)
tf = Frame(self.main), side=RIGHT)
self.logo = PhotoImage(data=images.icon)
Label(tf, image=self.logo).pack(side=TOP)
tf.pack(side=BOTTOM, fill=BOTH, expand=1)

def display(self):
