glsel only affects the target of gl commands and doesn't affect anything
else. It would not affect the use of an hwnd of an isigraph for
wsaasync.

automatic glsel.
Oleg, I understand automatical glsel is very useful for most cases but
it also
break codes that uses isigraph not as a picture control. Chris's grid
provides
an excellent example that all kinds of magic on isigraph.
eg, in winsock the hwnd of an dummy isigraph (msgsink) is passed to
sdasync that
will trigger a user event (form_msgsink_mbldown) instead of system
socket event.
information sent by WSAAsyncSelect will be decoded from sysdata.
NB. =========================================================
NB. WM_LBUTTONDOWN=16b201
sdasync2=: 4 : 0"0
if. IFUNIX do. 'not implemented under Unix - please use sdselect'
assert 0 end.
flags=. OR/ FD_READ,FD_WRITE,FD_OOB,FD_ACCEPT,FD_CONNECT,FD_CLOSE
hwnd=. x.
if. >{.WSAAsyncSelectJ ({.y.);hwnd;16b201;flags do. sdsockerror ''
else. 0 end.
)
NB. this have nothing to do with painting
NB. and there are other isigraph on the same form
form_msgsink_mbldown=: 3 : 0
... decode lparam from sysdata
)
NB. =========================================================
I did not mean your purposal is wrong, but only it will break some
codes and
there will be no workaround as glsel is automatic (Similar to
autofocus that
leads to unpreventable change of focus). As I said, I don't mind auto
glsel to
be implemented so long as it can be disabled.
