KErrPermisionDenied Error indicates a capability problem.

Keycapture module requires SwEvent capability. Did you sign the scriptshell with the SwEvent capability?

scriptshell signed with SwEvent capability

hello jiten_shah18

is very simple go to symbiansigned online submit your sis with correct IMEI of your sis and just accept the terms and condition then you are complete with the signing procedure, a email will be sent you for information about your signed sis.

Hope it helps

Hi

I have installed python shell script signed at Symbian signed in my phone.My application is as shown below:

import keycapture
from key_codes import *
import e32
import appuifw

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

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

app_lock=e32.Ao_lock()
app_lock.wait()

It is working perfectly using the script shell interpreter.But when I install it as a stand alone application using application packager it gives the following error:

"Traceback (most recent call last):
File "launcher.py",line 43,in<module>
execfile('default.py',default_namespace)
File"default.py",line 17,in <module>
capturer.start()
File "C:/Documents and Settings/.......\keycapture.py", line 84, in start
SymbianError:[Errno -46] KErrPermissionDenied

How can I solve this? I dont know if I have SwEvent capability.How can I include this using application packager?

Instructions for specifying capabilities: http://wiki.forum.nokia.com/index.ph...s_to_my_app.3F
After that just sign the sis file (even open signed online will do) and it should work.

[Simil Susan]

Cant I use self sign?...I tried but the stand alone application is not getting installed giving error "Required application not granted".I have given it for open sign online.

If I open sign it with the IMEI number will it be possible to install the application in a different phone? Actually I want to install my application in 3 phones.So for that should I sign the sis each time with each IMEI number? I prefer to get a single signed application which could be installed in all s60 3rd edition devices I want.

No. SwEvent is a capability that can only be granted through Symbian Signed.

I tried but the stand alone application is not getting installed giving error "Required application not granted".I have given it for open sign online.

Please tell us exactly what you did. Every single step, as detailed as possible.

One IMEI = one device. If you want more you will have to use one of the other Symbian Signed options.

Bogdan,

Thanks for your response.I think I have to use Express signed or Certificate signed for my purpose.

But I am facing a problem in my application.Let me explain what I am trying to do:

I have a list box with 5 names.When I scroll up it should read out the corresponding name.I am using module audio to read out.To sense the movement of scrollbar up and down I used keycapture module.When capturing is started it is reading out the names but the scrollbar is not moving up and down.

How can I solve this?

I am also using module _appswitch .But after open signing my application appswitch is not working.With self sign it was working fine.Does appswitch any capabilities other than user capabilities?

I am expecting some advices ASAP.

Regards
Simil

If you mean that when you are pressing the down arrow, for example, the phone reads the next name but does not highlight it, then you should add this to the end of the function that is called when the key press is detected:

listbox.set_list(names_list, listbox.current() + 1)
#listbox is your Listbox instance
#names_list is the list of names you want the phone to read

More info about those methods is available in the PyS60 documentation, in the section about Listbox.
I hope I understood the problem. If not, please explain it again.

As for the appswitch issue, how is it not working? Does it throw an error? Does it simply do nothing?

[Simil Susan]

No appswtich does not throw an error.It is simply doing nothing.

I think you understood my problem.But I tried it its not working.The following is my code:
#Names.py
import _appswitch
import keycapture
from key_codes import *
import audio
import os
import appuifw
import e32
import graphics

c = 0

icon0 = appuifw.Icon(u"arun.mbm", 0, 0)
icon1 = appuifw.Icon(u"manu.mbm", 0, 0)
icon2 = appuifw.Icon(u"susan.mbm", 0, 0)
icon3 = appuifw.Icon(u"lisal.mbm", 0, 0)

items = [(u"Arun", icon0), (u"Manu", icon1), (u"Susan", icon2), (u"Lisa", icon3)]

def handle_selection():
global lb
if items[lb.current()][0] == "Arun" :
calls arun#code to call arun
elif items[lb.current()][0] == "Manu" :
calls manu#code to call manu
elif items[lb.current()][0] == "Susan" :
calls susan
elif items[lb.current()][0] == "Lisal" :
calls lisa

def loop():
_appswitch.switch_to_bg(u"Names")

lb = appuifw.Listbox(items, handle_selection)
appuifw.app.body = lb
appuifw.app.menu = [(u'Hide',loop)]
appuifw.app.exit_key_handler=loop



def audio():
global c
if c == 1:
playMP3wf()
elif c == 2:
playMP3mp()
elif c == 3:
playMP3df()
elif c == 4:
playMP3rf()
elif c == 5:
playMP3rspns()


def down():
global c
c += 1
if c == 6:
c = 0
audio()


def up():
global c
c -= 1
if c == -1:
c = 5
audio()


def cb_capture(key):
if key == EKeyUpArrow:
up()
if key == EKeyDownArrow:
down()
listbox.set_list(items, listbox.current() + 1)


capturer = keycapture.KeyCapturer(cb_capture)
capturer.keys = (EKeyUpArrow, EKeyDownArrow)
capturer.start()

app_lock = e32.Ao_lock()
app_lock.wait()


In this it is not going to background when exit key or the hide selection is used.But it was working fine when I installed without signing(that is when I didnt use the key capture module).
Please check if the code in bold is correct.Is that where I have to put it?I didn get names_list.Is it items in my code?

Regards
Simil

[bogdan.galiceanu]

names_list is items in your code.

I though you couldn't move through the list because when you capture the arrow keys, you replace their effect with the one you specify through the callback functions. That's why I suggested you add that code in your functions, so that you force the currently selected item in the list to move in the direction of the arrow you press (note that you should put it in your up and down functions, not in the cb_capture function, and make sure the effect is appropriate. Hint: - 1 for up, + 1 for down).

If that doesn't fix it please explain the problem again.

[Simil Susan]

Thanks a lot Bogdan...it worked perfectly...

Any idea about why appswitch is not working?...does appswitch need any seperate capability?

If some one knows the answer please help...

[Simil Susan]

Hey appswitch has started to work some how...But one more problem.If I scroll down quickly the audios are overlapping and creating a mess.Is there any method to stop an audio file when another audio is called?

[bogdan.galiceanu]

You could perhaps check if an audio file is playing and, if it is, stop it. The things you need to use are described in the PyS60 documentation for the audio module.

A strange thing is that the documentation says

Currently the module does not support playing simultaneous audio files, calling play to a second Sound instance while another audio file is playing, stops the earlier audio file and starts to play the second Sound instance.

so your app's behavior is not normal
