[ltk-user] newbie questions about listbox

Hi, I am working my way through some tk examples (http://www.bin-co.com/tcl/tutorial/widgets4.php) and converting them to ltk. I figured that would be a nice way to learn ltk. I am now stuck with listbox. Here are the specific questions: - How do I initialize the list (populate it with items)? - How do I get the index of the current selection? I am assuming it may be an argument to the event function, but without initializing the list, I could not test that hypothesis - How do I get the list item at the particular index. As I noted before, I would be happy to post the resulting code in form of a (newbie) ltk tutorial. Thank you, Mirko
