[Gambas-user] latitude and longitude on a map

[roberto.premoli at tiscali.it]

  Hello,
I have a list of towns with their own coordinates (latitude
and longitude). I would like to place in a combo box: as i select one,
a
marker must appear on a map (and disappear when i select another).
I
write here to ask if a similar program already axist at source to study,
or at least where I can find a demo to start with, because i am newbie
about this topic.
I run Gambas 3.12.2 on Debian 10 amd64.
Thanks
