I have what is a noob's confusion about this that will lead to bigger
problems for me later on if I don't clear it up.
Don't worry, this kind of confusion abounds in GUI toolkits of all
kinds not just wxPython.
In wxPython what a user normally refers to as a "window" is known as
a
frame. And what is known in wxPython as a window is an object such
as a
TextCtrl object. At least that is what I take from "wxPython in
Action".
Correct, and the latter usage is common parlance in most GUI
frameworks.
A window is any visible area of the screen, including widgets. The
name
for the top level object varies from toolkit to toolkit.
Now, wxApp has a method called SetTopWindow and you normally pass
your
wxframe object to it so that it knows what is to be top object.
I think this is historic since many early toolkits had some kind of
setTopWindow method (Microsoft and Borland, and at least one X windows
toolkit all did). The name in wxPython is simply a reflection of the
underlying
C++ wxWidgets which, I think, simply reflects the historical legacy.
Why isn't it named something like SetTopFrame?
What am I missing?
Nothing, it's just one of the many accidents of programming legacy.
Like why does Lisp use "car" to get the first item off a list? Because
that's the machine instruction that did it on the computer they built
the first Lisp on... There are a lot of these historical accidents
that
creep into programming languages. Learn to love them! :-)
