Hi,
In the wxWidgets help, wxComboPopup instances should have a member
m_combo pointing to its parent, which is a wxComboCtrl. In wxPython,
this member property is missing. Then how can wxComboPopup know with
which wxComboCtrl it is associated?

Use the GetCombo method.

It returns a wx.ComboCtrl object rather than the class that derives
from wx.ComboCtrl, so some attributes are missing. Is it possible to
get the derived class instead of the base class?
Also, the wx.ComboCtrl instance so returned will return None when its
GetTextCtrl method is called.
Second question. How does wx.ComboCtrl notify the user that a
selection is made by the user? Binding to wx.EVT_COMBOBOX doesn't seem
to work in a modification to the wxPython demo.

Yes, but I'll have to tweak the wrapper to do it.

I think my issue is similar.
Sorry, but I can understand how to change the Behavior of derived ComboCtrl.
Please, can You provide more detailed explanation how to solve this:
import wx
import wx.combo

#----------------------------------------------------------------------
# This class is a popup containing a TreeCtrl. This time we'll use a

class TreeCtrlComboPopup(wx.combo.ComboPopup):
# copy from ComboCtrl-Demo
app = wx.PySimpleApp()
dialog = wx.Dialog(None)
combobox = wx.combo.ComboCtrl(dialog, style=wx.CB_READONLY)
set = TreeCtrlComboPopup()
combobox.PopupControl = set
get = combobox.PopupControl
text = wx.TextCtrl(dialog, style=wx.TE_MULTILINE)
text.Value = 'set == get: %s \n set is %s \n get is %s' % ( str(type(set) ==
type(get)), type(set), type(get))
sizer= wx.BoxSizer(wx.VERTICAL)
sizer.Add(combobox)
sizer.Add(text, 1, wx.EXPAND)
dialog.Sizer = sizer
dialog.Show()

The C++ wxComboPopup class does not have the necessary magic to be able to allow wxPython to look up the original Python proxy object from the C++ and return it from methods like GetPopupControl. Instead you'll need to keep a reference to the object yourself.

Ok, but why in API its written:
"GetPopupControl(self) Returns the current popup interface that has been set
with SetPopupControl.". It's a tad obscure for me.
And why do ComboCtrl don't have such determined Place to store really Reference
for PopupCtrl?
one Example again:
if __name__ == '__main__':
app = wx.PySimpleApp()
dialog = wx.Dialog(None)
comboCtrl = wx.combo.ComboCtrl(dialog, style=wx.CB_READONLY)
set = TreeCtrlComboPopup()
comboCtrl.PopupControl = set
comboCtrl.__dict__['myPopupControl'] = set
get = comboCtrl.PopupControl
get2 = comboCtrl.myPopupControl
text = wx.TextCtrl(dialog, style=wx.TE_MULTILINE)
text.Value = 'set == get: %s \n' % str(type(set) == type(get))
text.AppendText(' set is %s \n' % type(set))
text.AppendText(' get is %s \n' % type(get))
text.AppendText('set == get2: %s \n' % str(type(set) == type(get2)))
text.AppendText(' get2 is %s \n' % type(get2))
sizer= wx.BoxSizer(wx.VERTICAL)
sizer.Add(comboCtrl)
sizer.Add(text, 1, wx.EXPAND)
dialog.Sizer = sizer
dialog.Show()
app.MainLoop()

It does return the same C++ PopupControl that was set previously, the trouble is that a new Python proxy object is being wrapped around the same C++ pointer, and since it can't determine the true type of the pointer it is creating a proxy of the base class type instead.
