[libreoffice-users] Macros : How to solve concurrency/Reentrancy in events procedures ?

Hi,

I'm using LibreOffice 5.2.7.2 with HSQLDB database server (not embeded).

I've got a problem with form events management, so I'm looking best 
practice to manage reantrancy :

1) I'm asking myself if each event is a different trhead ?

2) Do you know sample of code with uno API to manage Mutex 
<https://api.libreoffice.org/docs/cpp/ref/a00130.html> in Thread that I 
could use with Basic macros ? I couldn't find anything like this into 
"Marcelyy, B., Godard, L. - Programmation OpenOffice.org 3 - Eyrolles, 
2009" Do you know a other book more closer with Uni APIs ?

3) Is it possible to replace default Form listners by handlers, in order 
to refuse reantrancy by rejecting unecessary events ?

4) Do I prefer modify the default Form controler in order to manage at 
source level the reantrancy problem ? Do you sample of code to do?

5) Is it possible to write a mutex by home, I could use into my Forms 
listners ? For exemple, using a global variable as counter events and a 
wait() call to manage priorities ...

By the way, I noticed in my macro a global variable instanciated into 
one of my form listner may disappear... I was reading into "Useful Macro 
Information For OpenOffice.org By Andrew Pitonyak (p.373) 
<https://www.google.fr/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwjW1Jzvr9TYAhWLZlAKHT_2BOAQFggzMAA&url=http%3A%2F%2Fwww.pitonyak.org%2FAndrewMacro.odt&usg=AOvVaw0vIQyJ56mQzdDCtVkPOXGB>" 
that controlers may be replaced by others ones, and listners detached... 
So I'm asking myself if there is something similar explaining my 
problem. But I'm only moving from one record to next one, and my 
variable is global ...

Thank you for your help !

Patrick
