If in a program I create a window several times and I don't make the disconnect stuff, will it use a lot of memory or the same signal handler will be used?
Memory is leaked each time.
Wow, that sounded allarming :-/
This is untrue, when your window is destroyed/finalized, all memory allocated for signal marshalling will be freed.
Yes. I misread it as creating a window many times and not destroying old ones.
