[Plib-devel] RE: FlightGears puList code

[Fay J. F C. AAC/W. <joh...@eg...>]

Erik,

	Please excuse the delay in getting back to you.  I haven't been able
to look at the "puList" code yet but I will.  On principle I don't see
anything wrong with adding it to "puAux".

Hi John,

FlightGear has been shipped with a puList (a scrolling PUI list box) for 
ages ans we have hit a problem recently:

Someone has provided a workaround for it but it depends on a define that 
might be used in the future:

Now I was thinking that it might be a good idea to add this code the 
puAux and get it settled from now on. Unless you can point me to another 
PUI list pox widget, would you be so kind to add this to puAux?
