Hi all,
I'm writing a gtk app to acquire from a videocamera and display the
acquired frames.
When I start the acquisition pressing a button, the callback, connected
to the button, doesn't return the control to the applcation and I can't
stop the acquire!
How can I make a not blocking callback?

Thanks
pablo

You could try starting a new thread in the callback. If you go this
route, you may want some code to prevent too many of these threads
from being created (eg disable the button while the code is running).

Cheers,
Kevin
