New question #671452 on Sikuli:
https://answers.launchpad.net/sikuli/+question/671452
I'm currently in the middle of a script used to observe many regions at once,
all pointed at IP camera feeds. The script is to see if any of the screens
shown on the feeds go dark at any given moment.
I've used a class to create all of my onAppear and observeInBackground methods
since they all follow the same process, and gave the __init__ arguments of
'self', 'name', and 'region'. I was hoping to make another method that would be
used as the handler for these onAppears called 'trigger_handler', that would
alert us as to which region has been triggered when it happens (see below).
def trigger_handler(self, event):
###
# This is the method that gets called whenever the onAppear observation
is triggered. Health check will send with the
subject
line noting which screen is down and send both pictures
###
popup(self.name+" appears to be down, can you confirm?")
My idea was to reference this method as the handler in the onAppear method (see
below), but when doing so the handler triggers immediately whether the onAppear
is true or not.
def start_observe(self, reference):
###
# This is the method assigned to each region being observed that looks
for its own reference image and calls its own event
handler when triggered
###
reference = str(self.region)+"_out"
self.region.onAppear(reference, self.trigger_handler())
self.region.observeInBackground(FOREVER)
I'm also pasting the class itself and the __init__ that directly follows just
for reference, and also a couple of the class objects below that.
Thank you so much for any help and advice, I am just totally stumped!
class event_handler():
###
# This is a class that contains all handlers for observation regions. The
__init__ helps us define the name of the screen we are
currently observing,
# while the trigger_handler method is assigned to all objects of the class
and gets called for that specific object when the
onAppear gets triggered
###
def __init__(self, name, region):
self.name = name
self.region = region
rr02_handler = event_handler("Reader Rail 2", rr02) ###(rr02 and rr08 are
regions defined earlier on before the class.
rr08_handler = event_handler("Reader Rail 8", rr08)
def start_all_observe():
rr02_handler.start_observe(rr02_out)
