Re: [Scilab-users] Long delay before callback

2022-09-22 Thread Stefan Du Rietz

Stéphane, thank you very much for your example!

However, everyone of my callback functions is short-lived: it just does 
a few things and exits. Sometimes the response is instantaneous but 
sometimes it takes a long time. I have not so far managed to notice any 
pattern in that.

Hi, thanks.
Yes, but it doesn't seem to make much difference. And I don't exactly 
understand the different options.

Hello Stéphane,

a minimal example works OK all the time ...

So, there must be something in my rather complex GUI environment, 
with many private functions, that does not. But since I get no 
warning or error messages, I don't know how to proceed.


Can the delays be due to timeouts?

Hello,
I have a problem with GUI: when I choose a menu or press a button, 
sometimes it takes half a minute before the callback starts. 
Scilab is then using 100% of CPU, according to Bash top. I suppose 
it has something to do with Java? What can I do?
