Use a unique wxWindow ID or wxWindow::Get/SetName() to give each
notebook page a unique name so you can find the window no matter what.
You can also use wxWindow::FindWindowById/Name(). Doing this should be
the cleanest solution since you will definitely know what window
you're getting.

Here's how to get information about what an object is and how to cast
wxObject derived classes up and down their class hierarchy.
The wxClassInfo is may not be right for all classes and this function
only works for wxObject derived classes, but it will work for all
major classes. You can also just call Lua's tostring() function to get
the object type as string name. NOTE! The integer number is NOT fixed
between versions, but will be constant within a single run.
Here's some code run in the wxLuaEdit console to show some of the
possibilities and what works and what doesn't.
f = wx.wxFrame(wx.NULL, -1, "Hello")
w = wx.wxWindow(f, -1)
f:Show(true)
c = wx.wxComboBox(w, -1)
ci = c:GetClassInfo() -- from wxObject
print(ci)
userdata: 0x161d918 [wxClassInfo(0x7f33d2cf8b40, 23)]
print(ci:GetClassName())
wxComboBox
print(tostring(c))
userdata: 0x161b368 [wxComboBox(0x1614c00, 134)]
cw = c:DynamicCast("wxWindow")
print(cw)
userdata: 0x16273f8 [wxWindow(0x1614c00, 368)]
ciw = ci:DynamicCast("wxWindow")
Error: Lua: Error while running chunk

dialog_from_combobox = cw:DynamicCast("wxDialog")

Hope this helps,
