Frank,
You need to insert items, as well as setting the item's string.
So, before your line:
self.lc.SetStringItem(i, 0, "%d" % i)
Add a line like this:
self.lc.InsertStringItem(i, label);
Where label is a string that serves no purposes (doesn't get displayed) that
I've deteremined. It's all the same on the Win32 api - this is a common
mistake.
Tom.
