G'day Helen,

I'm not a Wx user; however, the documentation seems to indicate that the value you've used for position (i.e. [20,30]) needs to be a Wx::Point instance. See Update below for an issue with the argument list.

I agree that the documentation is not optimal. Here's the links I followed to glean the above information:

• Wx
• wxPerl
• wxWidgets
• Classes by category
• wxListCtrl
• wxPoint

I also found Wx::Perl::ListCtrl which you may be interested in: its description claims it provides "a sane api for Wx::ListCtrl".

Update: Your Wx::ListCtrl->new() call contains an additional argument ('Report',    # label) which is throwing position, and subsequent arguments, off by one. Accordingly, the error message you received refers to 'Report' not being a Wx::Point.
