There is also a nice thing you need to know about Python if you
already do not know. That is the fact that all empty collections bool
to False. This makes Truth testing easier.

Thanks for the reply.
I used your modified code to test. I ran the code on Windows Python 2.4
tcl/tk 8.4. When I opened the ui I:
1) click browse button
2) file dialog opens and I double click the file. When I do this, the
selected file path is entered in Entry field. I don't need to close

Oops,
That should have been,
class MyApp:
def __init__(self, parent):
self.myParent = parent
self.myContainer1 = Frame(parent)
self.myContainer1.pack()
self.entry = Entry(self.myContainer1)
self.entry.grid(r
I think you are better off not binding a button like you are doing.
Use the "command" option to get the behavior you want. E.g:
class MyApp:
def __init__(self, parent):
self.myParent = parent
self.myContainer1 = Frame(parent)
self.myContainer
