Yes, I read it but "argument 2 of wxXmlResource_LoadObject()" was somehow misleading, I thought it is "customDlg", not "self".
Replacing "self" with "None" eliminated the error, thank you, but got me into another. A message box states:
"Unknown style flag wxDEFAULT_DIALOG_STYLE"
(though
<style>wxDEFAULT_DIALOG_STYLE</style>
was generated by wxGlade)
and
"No handler found for XML node "object", class "CustomDlg"!"
(though there is such a handler, see below).
Thank you,
Cristina.
