Re: Trouble calling method from one class to another class

Take my advise with a smile because I am NOT the best programmer.  But, 
I have to say this is some very confusing code pxCore2.py.  I believe 
you do not have a handle on how OOP works within python. Also you copied 
code directly out of the wxPython demo but lacked the understanding of 
what was being presented. And I bet this is causing confusion and is 
also not allowing you to move forward.

When you define a class, you don't normally create an instance of the 
class within the definition of the class.

self._MyTreeCtrl = MyTreeCtrl is in the __init__ method of MyTreeCtrl.

so comment out "self._MyTreeCtrl = MyTreeCtrl"

I believe with wxPython 4.x the super() is used.

so

wx.TreeCtrl.__init__(self, parent, id, position, size, style)

is now

super().__init__(parent, id = id, pos= position, size = size, style=style)

You can review the what is needed to init wx.TreeCtrl by looking at the 
method in the source code.  In this case there are two signatures:

  TreeCtrl()

or  TreeCtrl(parent, id=ID_ANY, pos=DefaultPosition, size=DefaultSize, 
style=TR_DEFAULT_STYLE, validator=DefaultValidator, name=TreeCtrlNameStr)

Therefore, depending on your needs you could just use:

super().__init__()

At this point I stopped because the GUI opened and I'm not sure what you 
are trying to do.  If it is to list a directory there is a widget called 
'FileDialog'.
