wxPython: combining wxListCtrl and wxCheckBox

[Mark Carter]

I would like a wxListCtrl with 3 columns in it. The number of rows in
it will vary during run-time. In the first column of each row should
be a wxCheckBox, which the user can check or uncheck.

Is such an arrangement possible?
Any example source code?

wxCheckListBox comes close - but not close enough. Unfortunately, it
does not derive from wxListCtrl, which contains the function
InsertColumn() needed for multiple columns
