You can disable listbox item(s) by preceding it by slash '\', e.g.

With Thisform.Listbox
  AddItem('Enabled')  
  AddItem('\Disabled')
Endwith

You could explicitly set listbox column width, by setting ColumnWidths property, and then check actual mouse location in Listbox.Click event; but it make sense to use grid instead of listbox to get this and many other functionalities.
