Hi folks,

I made a small but handy update to the dialog module.

For those who don't know, dialog is a library containing two C++ wrapper for the Wait and the Progress dialogs.

You can now give a call back function to Wait that will be called if you press the Cancel button.

import e32, appuifw
from dialog import Wait, Progress

appuifw.app.title= u'Hello dialog'

## Cancel callback
def cancel_cb():
    print "cancel callback!!!"

# Wait(label=u'', [True/False, cancel_cb])
dlg = Wait(u"Hello Wait note :)", True, cancel_cb )
dlg.show()
print "Show"
e32.ao_sleep(2)
dlg.show()
dlg.set_label(u'Wait! Don\'t go :\'(')
print "Change label"
e32.ao_sleep(1)
dlg.close()
print "Wait, that's not finished!"
e32.ao_sleep(2)
dlg.show(u'Me again ;)')
e32.ao_sleep(2)
dlg.close()
e32.ao_sleep(2)
dlg.show()
print "Show again with the last label"
e32.ao_sleep(2)
dlg.close()

Progress is still amazingly bugged so there's no need to mention it for now, I already have some amazing crash tests

I'll take care of that later in late September if nobody propose a fix before.

You can get the module as well as some other in my download section http://lfdm.net/thesis/index.php/dlm/

If any problems with the installation packages let me know. I have so far tested successfully the updated module on N93 and 3rd edition emulator.

Cheers,

Hello ,

Test the new dialog (only the Wait part ) because the progress is awfull unfortunately with the new option !

import e32, appuifw
from dialog import Wait
from e32 import ao_sleep as sleep

appuifw.app.title= u'Hello dialog'

def cancel_cb():
  print "cancel callback !"

def end_script():
  script_lock.signal()

def wait(glob,called):
  if called:
    dlg = Wait(u"Hello Wait note :)", glob , cancel_cb )
  else:
    dlg = Wait(u"Hello Wait note :)", glob )  
  dlg.show()
  print "Show"
  sleep(3)
  dlg.show()
  dlg.set_label(u'Wait! Don\'t go :\'(')
  print "Change label"
  sleep(2)
  dlg.close()
  print "Wait, that's not finished!"
  sleep(3)
  dlg.show(u'Me again ;)')
  sleep(3)
  dlg.close()
  sleep(3)
  dlg.show()
  print "Show again with the last label"
  sleep(2)
  dlg.close()
  print "that's finished !"


script_lock=e32.Ao_lock()
appuifw.app.menu=[(u'Wait ', lambda : wait(0,0)),(u'Wait with cancel key', lambda : wait(1,0)),(u'Wait with cancel key callback', lambda : wait(1,1)),(u'Exit', end_script)]
appuifw.app.exit_key_handler = end_script 
script_lock.wait()

Tested with N95 and PyS60 1.4 and dialog 0.3
feedback : all features seems to work without any errors when you quit the app with exit option it returns to Python menu but ... when you quit Python it displays : "Application closed: Python KERN-EXEC 3"

So not so perfect yet ;-)

I just tested your script and mine on:

• N90
• N93
• E61
• 3rd edition emulator

Result: everything works fine So I don't really know how to reproduce it

I got "Python KERN-EXEC 3" panic code at the beginning when trying to code the callback even if the function pointer existed. The fix was to surround the callback call with :

        PyEval_RestoreThread(PYTHON_TLS->thread_state);
        app_callback_handler( iCancelCallback );
        PyEval_SaveThread();

If you have time you could try to add it to the Wait destructor and let me know if it fixes the issue

I really would like to use your fine component, but I don't know how to deploy it. I fear a bit the 1st, 2nd, 3rd chaos... and I wouldn't like to ask my users to download the component before.

What are the possibilities to overcome this?

Hi neil.young,

If you deploy installation packages (.sis, .sisx) you just add the library installation package in your application one, like you would do with PyS60 for example.

That's possible? I didn't know that. Is the "forgeign" SIS called automatically than?

dlg = Wait(u"Hello Wait note ", True, cancel_cb )
dlg.show()

After printing out "cancel callback" Python still crashes on N70.

And - if the script runs into a "processor intensive part" (e.g. urllib things), the dialog never pops up.

Too bad.

Regards
