AnonymousMonk: Thank you. Using your post, and the info in this: http://wxpython-users.1045709.n5.nabble.com/column-header-doesn-t-change-td2341548.html (showing that this:

$this->SetItem($item);

is necessary), I succeeded in changing an item's font in Wx::ListCtrl.
Here is the font-changing sub:

sub OnBold {
   my $this = shift;
   my $item = $this->GetItem(1);
   my $f = Wx::Font->new(12, -1, wxNORMAL, wxBOLD, 0, 'times new roman
+');
   say "In OnBold, \$this= $this, \$item = $item, \$f= $f";
   $item->SetFont($f);
   $this->SetItem($item);
} #1    end sub OnBold

and the entire program (tested):

Stefan, hdb and James: the object pointers were fine originally (as you can see).

My next problem: how do you set/change size and font of ListCtrl column headers. (As usual, no documentation). I'll start a new post for that: http://www.perlmonks.org/?node_id=1025489

Many thanks to all the responders, who spent time on this thread. - Helen

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
