Re: Importing wxWidgets Help

You have two immediate problems.  First, in CoreFrame where you instantiate 
MyTreeCtrl, you are passing `vbox` as the parent.  This is one of the more 
confusing aspects of wxWidgets.  The windows and the sizers live in two 
separate hierarchies.  A sizer controls a set of windows, but it is not 
itself a window, and thus cannot be a parent.  You need to pass "self" as 
the parent, so the frame becomes the parent window.  Essentially, you 
create a whole bunch of windows in a hierarchy, and then you add those 
windows to sizers (which have their own hierarchy) to control their 
placement.

The second problem is in "MyTreeCtrl.__init__" when you call 
"wx.TreeCtrl.__init__".  If you look at the documentation, you'll see that 
the parameters for that start out self, parent, id, pos, size, style, ...  
 You are not passing a "pos", which is why you get an error.  Now, that's a 
perfectly OK thing to do, but once you omit a positional parameter, the 
rest have to be specified by name:  "wx.TreeCtrl.__init__(self, parent, id, 
size=size, style=style)".  That should get you a little farther.
