# To subscribers of the xforms list from Nicolas Castagne <Nicolas.Castagne@imag.fr> :
Hi,
I have a small problem using Xforms in my quite nice ( -:) )
multiple process app. I did imagine a solution, but i wonder if there is a
better - or simpler - one.
All the forms, objects and Xevents are to be managed by the parent
process, except, if possible, the draw acton in a GLcanvas.
This GLcanvas is quite long to draw, so that I'd like one of the
child process to perform drawing operations.
I may achieved this using a GLbuffer shared in a shared memory
space. The parent process would ask the child to draw in the buffer, and
when finished the child would send a message to the parent so that it
performs the buffer swap.
This solution may be a bit heavy indeed...
The simplest would be to let the child process draw in the window
created (and event-managed) by the parent.... And that gives my first
question : "Can a child process draw in a window created by the parent -
and only draw, since the event management is achieved by the parent
process ?"
Last but not least :
Any other idea ?
Thx all,
NC;
