cbox = Obj.Create('TComboBox')
cbox.Parent = form -- set to containing object's name
cbox.Top = 25
cbox.Left = 25
cbox.Width = 180
cbox.Items.Add('a line in the combo box')
-- add more lines
cbox.ItemIndex = 0 -- the first item is selected
cbox.OnChange = function(pSender) --[[ event fires immediately after the user edits the text in the edit region or selects an item from the list. The Text property gives the new value in the edit region. --]] end
