Hi Jim & Mark,
Thanks for the reply, my program is
working in HP unix, I am able to get both the out put
in a same window(overlayed), the only change in Linux
code is in XtOpenDisplay() part, there in HPUX the
function call using the display parameter as "0:0" and
second one using "0:1".
In Linux the display perameters with "0:1" is
giving error, so I made it NULL for both the
XtOpenDisplay() function calls, how to achive in Linux
the same functionality, since I am using NULL as
display parameter I am getting two different display,
unable to achive overlay.
I am new to this X-window programming and
overlay concept, pls explain.
thanks in advance,
Bala.
