Forum: Ruby how to trigger a thread by event

Hi,
As you know, ruby thread start to execute when created, like
Thread.new do      ......end
Here my question is how can I defer the thread execution until something 
happened, like an event?
Thanks,Brian

Huh?  Is this a serious question?  The solution seems pretty obvious.

Cheers

I am not sure I understand what you want to do. Threads can be stopped
and restarted. If, from within the code of your thread, you call first
thing

Thread::stop

then, whenever you need the execution to restart, you can call t.run
from your main process. Look at the example that is returned to you by
running.

ri Thread::stop

I do not recommend doing that.  Generally one should rather use thread
synchronization primitives to control execution of threads.
