Question #670456 on Sikuli changed:
https://answers.launchpad.net/sikuli/+question/670456
Description changed to:
************************* This works after having fixed some issues:
Using
FindFailed.setHandler(ffhandler)
takes care, that every Region created thereafter inherits the setting (handler
will be visited on FindFailed)
In Jython/Jruby scripting:
If you want this behaviour for the standard SCREEN object too, you either have
to issue a
use()
after the global setting or use
setFindFailedHandler(ffhandler)
The latter one is the only to use, if you want the behaviour only for
the global SCREEN object.
Be aware:
If you do not want your script to abort after returning from the handler, you
have to issue
event.setResponse(SKIP)
in the handler before the return.
Depending on what you have done in the handler, one of the other options RETRY
or PROMPT might make sense as well.

Let's assume I have a rather lengthy SikuliX script that can basically fail at
any point - usually find failed.
Instead of modifying the whole script to catch every possible error, my idea
was to use some kind of "supervisor" script instead.
The supervisor calls the script and if anything goes wrong there, the GUI in
question is reset to its initial state by the supervisor which then calls the
script again.
I got this idea working, but of course every time a find failed occurs in the
called script everything comes to a stop.
What I would need is a way to simply exit a script (so the supervisor can take
over) every time a find failed occurs. Is this possible?
"setFindFailedResponse()" doesn't seem to have the proper parameters for what I
have in mind.
Setting it to "SKIP" won't do it because if an error occurs, the GUI HAS to be
reset to its initial state.
Edit: tried using setFindFailedHandler:
setFindFailedHandler(resetGUI)
def resetGUI():
#do stuff
#rest of the script
Still, the script just stops when encountering a FindFailed error
instead of calling my resetGUI routine. In addition to that, I still
have the problem that I would need to start the script at the beginning,
no matter where an error occured.
Edit2: I am running SikuliX version 1.1.2 on Windows10. Yet even putting
"setFindFailedResponse(SKIP)" in the header, the script still throws an
exception when an image is not found...
...apparently, setFindFailedResponse gets overwritten by setFindFailedHandler.
But still, my handler function is not executed when a FindFailed occurs.
