The grid
, pack
and place
functions of the Entry
object and of all other widgets returns None
. In python when you do a().b()
, the result of the expression is whatever b()
returns, therefore Entry(...).grid(...)
will return None
.
You should split that on to two lines like this:
entryBox = Entry(root, width=60)
entryBox.grid(row=2, column=1, sticky=W)
That way you get your Entry
reference stored in entryBox
and it’s laid out like you expect. This has a bonus side effect of making your layout easier to understand and maintain if you collect all of your grid
and/or pack
statements in blocks.
