Switch application to foreground in pys60

korakot (Korakot Chaovavanich) — Mon, 17 Oct 2005 21:06:29 GMT

Taken from the 'appswitch' module here



import appswitch

print appswitch.switch_to_fg(u"Menu")

Updated (19 Oct 05)
==================
Now it can
- listing running applications
- switching them to foreground/background
- closing/killing apps



# listing

apps = appswitch.application_list(True) # true = include all

                                       # false = no hidden apps 

print apps



# to background and closing

print appswitch.switch_to_bg(u"TODO")

print appswitch.end_app(u"TODO")
