For some programs it may be useful to know whether they are running in the background or in the foreground. This is how to check the focus state of a program (using the standard PySymbian appuifw module):

import appuifw
 
#A function that tells us the focus status of the application is defined
def foc(status):
    if(status==1):print 'App is now in the foreground'
    else:print 'App is now in the background'
 
#We assign the function to the focus item of the Application class in appuifw
appuifw.app.focus=foc
