[wxPython] ListCtrl: How can I change the column header text at runtime?

[F. GEIGER]

Hi all,

with an InsertColumn(colnbr, "This is the header's text") I can add a column
with a header text "This is the header's text". How can I change the text at
runtime, say, after a click on an other control? I had no luck with
GetItem()/SetItem(): I can get at the items of the list elements only but
not at the headers.

AS Python 2.1.3, wxPython 2.3.2.1.

Any hints?

Best regards
