left soft key

[Anime]

Why is not possible to assign a function to the left soft key (Options)? If yes, how to? I've the same problem with the key_codes module: EKeyLeftSoftkey is not recognized. Thanks for you help.

You can detect when the left softkey is pressed with the keycapture module and call a function. See this thread and the PyS60 Library Reference for details.

Why the EKeyLeftSoftkey keypress function does not assign the "choise" selection list at the execution?

import appuifw
import e32
import keycapture
from key_codes import *

def choise():
    index = appuifw.selection_list(choices=L , search_field=1)

    if index == 0:
        appuifw.app.body=appuifw.Text("E32USER-CBase (63)")
        appuifw.app.exit_key_handler=choise

    if index == 1:
        appuifw.app.body=appuifw.Text("E32USER-CBase (69)")
        appuifw.app.exit_key_handler=choise

L = [(u'E32USER-CBase 63'),(u'E32USER-CBase 69')]

canvas = appuifw.Canvas() 
appuifw.app.body = canvas

def cb_capture(key):
    if key == EKeyRightSoftkey:
	                print "Left softkey pressed"
    if key == EKeyLeftSoftkey:
		        choise

capturer = keycapture.KeyCapturer(cb_capture)
capturer.keys = (EKeyRightSoftkey, EKeyLeftSoftkey)
capturer.start()

def exit_key_handler():
    app_lock.signal()
    appuifw.app.set_exit()

app_lock = e32.Ao_lock()
appuifw.app.exit_key_handler = exit_key_handler
app_lock.wait()

You have to call the function with the parantheses (marked in red):

import appuifw
import e32
import keycapture
from key_codes import *

def choise():
    index = appuifw.selection_list(choices=L , search_field=1)

    if index == 0:
        appuifw.app.body=appuifw.Text("E32USER-CBase (63)")
        appuifw.app.exit_key_handler=choise

    if index == 1:
        appuifw.app.body=appuifw.Text("E32USER-CBase (69)")
        appuifw.app.exit_key_handler=choise

L = [(u'E32USER-CBase 63'),(u'E32USER-CBase 69')]

canvas = appuifw.Canvas() 
appuifw.app.body = canvas

def cb_capture(key):
    if key == EKeyRightSoftkey:
	                print "Left softkey pressed"
    if key == EKeyLeftSoftkey:
		        choise()

capturer = keycapture.KeyCapturer(cb_capture)
capturer.keys = (EKeyRightSoftkey, EKeyLeftSoftkey)
capturer.start()

def exit_key_handler():
    app_lock.signal()
    appuifw.app.set_exit()

app_lock = e32.Ao_lock()
appuifw.app.exit_key_handler = exit_key_handler
app_lock.wait()

Thanks for your help. Another doubt is related of the escaping of the parenthesis in text.

if index == 0:
        appuifw.app.body=appuifw.Text("E32USER-CBase (63)")
        appuifw.app.exit_key_handler=choise

With or without parentheses the selection list is not displayed at keypress.

[Anime]

bind(event_code , callback) seem do not work for callback=choise (selection list)

canvas.bind(key_codes.EKeyLeftSoftkey, choise)

[croozeus]

bind(event_code , callback) seem do not work for callback=choise (selection list)

canvas.bind(key_codes.EKeyLeftSoftkey, choise)

Hint: May be the use of lambda may help?

[Anime]

May be the use of lamda may help?

Can you give an example, please?

[croozeus]

Can you give an example, please?

In your case,

canvas.bind(key_codes.EKeyLeftSoftkey, lambda: choise())

[Anime]

canvas.bind(key_codes.EKeyLeftSoftkey, lambda: choise())

It seems not execute the selection list.

How I set capturer.start() at every canvas callback?
