dyad conew will automatically call create. You saw locale switched
probably it crash inside that locale and did not return to the caller
locale. I cannot comment further why your app crashed without seeing
a more complete source code. You will have a better chance to have
the problem solved if you can provide a minimum demo to reproduce the
error. Anyway, below is a minimum example to put TWO grids inside the
same form
require 'jzgrid'
cocurrent 'base'
FORM=: 0 : 0
pc form closeok;
xywh 0 0 200 240;cc g0 isigraph ws_border;
xywh 210 0 200 240;cc g1 isigraph ws_border;
pas 1 1;pcenter;
rem form end;
)
run=: 3 : 0
wd FORM
data0=: i. 3 4
data1=: i. 2 3
g0=: '' conew 'jzgrid'
show__g0 ('CELLDATA' ; 'GRIDID') ,. data0 ; 'g0'
g1=: '' conew 'jzgrid'
show__g1 ('CELLDATA' ; 'GRIDID') ,. data1 ; 'g1'
wd 'pshow'
)
run '' NB. testing
