This is the popup listbox window used by the Lcombobox class. It based on the Llistbox class but actually opens up as a popup style window (no title bar). It includes and extends the Lwindow_popup module defined in l_window.rb to make this Llistbox object look and act like a popup window. The color of the popup listbox always matches the color of the Lcombobox.
