...out, but I fairly often want to loop over a control with multiple items (eg Choice, ListCtrl, ListBox) to find or alter a particular item. So for those classes I wonder if we should add an ''each'' method that passes in turn each valid index into the widget: listbox.each { | i | set_item_text(i, item_text(i).upcase) } Or even: listbox.each { | i | self.item_text[i] = item_text[i].upcase } Anyway, shout if you love this or hate these... cheers alex

Nevertheless, I don''t know if I will use this feature often. Cheers. Chauk-Mean.
