I've an idea for an application that would pop to the foreground briefly when a system key (in this case Menu/Apps) is pressed.

Can Python handle this? i.e. wait in the background for a specific keypress and then pop up? I had a look in the PDF docs but couldn't see anything suitable....

Hi Steve
I came across this, I have not tried it as yet though but it may be of some help

appswitch - switch given application to foreground/background

With appswitch, you can control running applications in s60/python.

Following functionality is provided:
- listing applications
- switching them to foreground/background
- closing/killing

source & wins\udeb and armi\urel binaries included.

hello ,

Even with appswitch it's not possible coming to the foreground an application by pressing menu key :-(
But you can manually switch from python application to menu by pressing menu key and programming after a delay an automatic return to python application (ie foreground )
PyS60 1.3.1 add a new feature appuifw.app.focus to allow this (look documentation)

import appuifw
import e32
from appswitch import *

def cb_focus(fg_st):
    if fg_st:
        appuifw.note(u'back to fg','info')
    else:    
        appuifw.note(u'Wait 3 secs in bg ...','info')
        timer.after(5)
        switch_to_fg(u'Python')
        print application_list(1)
        print appuifw.app.full_name()
        
def quit():        
    timer.cancel()
    appuifw.app.focus=old_cb
    lock.signal()
    appuifw.note(u'END','info')
        
lock=e32.Ao_lock()
timer=e32.Ao_timer()
old_cb=appuifw.app.focus
appuifw.app.focus=cb_focus
appuifw.app.exit_key_handler=quit
lock.wait()

attention ! If you launch this code from Python application (not standalone) if you let screensaver appearing(wait for a long time) it triggers Kernel Panic ...
I don't know why (a bug ?)
