So here is an example of a vendor selling a very nice portable, easy-to-use graphics package. Everybody out there, raise your hand if you've heard of this product. Raise both hands if you have an idea of the price. I'm guessing that I won't see too many hands. And this is the group that is most interested in Ada. So tell us, John, why this product is virtually unknown here and certainly un-advertised "out there". Maybe someone from EVB might be able to answer that better than I, since I don't work there... These discussions always remind me of the TV commercial showing the forlorn toy store owner who never got any customers 'cause he neglected to put an ad in the Yellow Pages. EVB is guaranteed to remain small unless it figures out how to get visibility for its products. I suspect that it's a chicken/egg situation. Selling and supporting products in the Ada community costs can cost as much as the development, in my experience ... and we all know how non-easy it is to get word out to the miniscule Ada markets ... To put things back into perspective, the original intent of this post was to shed some light on any Ada projects who are contemplating reinventing a graphics framework on top of something as low level as Xlib. Don't do it unless you are absolutely sure you have no alternative. Chances are you will waste a *LOT* of money and never have something as nice in your system as HeraGraph or other graphics toolkits... Is there a www server that is dedicated to advertising *COMMERCIAL* Ada products? One of you "Team Ada" enthusiasts interested in maintaining one?
