Checking for sequntial visual events using Observe

Can you post your "_checkForStatusChange_sending" method?

You register the second onAppear listener to the same region as the first, so your first onAppear handler is still active if you run the observe() for the second time and may get triggered.

Hi j(j-the-k),
Thanks for taking your time to help me with my problem.
I have modified the code as below, now i have only one observe running ,but the handlers are not able to handle all the events, I am missing some events on a regular basis, so i have totally discarded the events and just waiting for the images to appear in a while loop ,which seems to do the job pretty good so far

with searchRegion:
            onAppear(Pattern("UnsuccesfullSend.png").similar(0.9),_checkForStatusChange_unsent)
            onAppear(Pattern("SuccesfuSent.png").similar(0.9),_checkForStatusChange_Sent)
           #onAppear(Pattern("SendingMessage.png").similar(0.9),_checkForStatusChange_sending)
            onAppear(Pattern("MacroError.PNG").similar(0.9),_checkForUnknownErrors)
          #onChange(75,_onChange)
           observe(FOREVER,background=False)

And my handler are like this

def _checkForStatusChange_sending(event):
    #print "Yes Found it"
    print "in _checkForStatusChange_sending"
    tblog.infoLog( "in _checkForStatusChange_sending")
    print event.pattern
    event.region.highlight(1)
    if event.pattern == "SendingMessage.png":
        print "SENDING_FLAG = True"
        global SENDING_FLAG
        SENDING_FLAG = True
        #print SENDING_FLAG
        #event.region.stopObserver() # stops the observation
def _checkForStatusChange_Sent(event):

    #event.region.highlight(1)
    print event.pattern
    match = event.match
    print match
    cp = match.getTopLeft().offset(10,10) # select a pixel, that has the background color
    .......................................
    Some Logging stuff
    .......................................
    event.region.stopObserver() # stops the observation

def _checkForStatusChange_unsent(event):

    #print event.pattern
    #event.region.highlight(1)
    match = event.match
    print match
    cp = match.getTopLeft().offset(10,10) # select a pixel, that has the background color
    ......................................
    SOME LOGGING
    ......................................
    event.region.stopObserver() # stops the observation

def _checkForUnknownErrors(event):
    #if exists(event.pattern):
    print "in _checkForUnknownErrors"
    #print event.pattern
    tblog.errorLog("Unknown Error")
    global UNKNOWN_ERROR
    UNKNOWN_ERROR = True
    event.region.stopObserver() # stops the observation

# print event.match

to leave it open
