Hi, wxPanel or wxFrame has nothing to do with self.currentItem, this
attribute is set to 0 in TestListCtrlPanel.PopulateList in mentioned
example, they register a handler for item selection

        EVT_LIST_ITEM_SELECTED(self, tID, self.OnItemSelected)

and in this hanler they set it to currently selected item:

   def OnItemSelected(self, event):
        ##print event.GetItem().GetTextColour()
        self.currentItem = event.m_itemIndex
        # [...]

This method tracks user selection, the other way is to find the
selected item when you need it:

    currentItem = self.list.GetNextItem(
        -1, wxLIST_NEXT_ALL, wxLIST_STATE_SELECTED)

this finds first selected item (first after -1).
