@cvp actually it does work on the regular version.
Not sure why i didnt see that before.
Thanks.

@cvp thank you!
when you say:

Altough last version of Pythonista offers an easy way to add an home screen shortcut for an edited script

do you mean the first link above?

@shinyformica hello!
how do you make a homescreen shortcut to a pythonista script?
thanks!

@cvp i have finished my first version of the program
here https://gist.github.com/1b67ba85ca7bd7b23c7058216895372c
this will:

• let you choose an album xxxx
• load the 200 first pictures
• present them in a photopicker
• from which you can build photo album pages (collage)
• it creates 2 new albums:
• xxxx_pages : the album pages
• xxxx_pages_and_photos: as it says. useful to upload the album in photoweb printing service for instance
• your own photos and albums are not modified

to see how to use it tap ‘?’ button: it opens a youtube video that shows it in action.

It is designed to work in lanscape mode
let me know how it works for you.

@cvp you know what? it works with ORIGINAL
looks like omz inverted TEMPLATE and ORIGINAL values
thanks.

@cvp thanks.
but it still doesnt work: now the button shows in gray, not white, and is not visible on my gray background.
I wonder how to get it simply as it shows in the editor?

@cvp i am in the final polishing phase of my project.
I have pb with button icons: they render in color when i want a gray rendering (the one shown in the editor).
my code:

img = ui.Image('iow:refresh_32').with_rendering_mode(ui.RENDERING_MODE_TEMPLATE)
    clear_button.image = img

any suggestion?
thanks.

@cvp i can understand what you feel: it is exactly what i thought the first time saw this! It took me several months to start to understand it, but once i did, bam!, it opened a huge box of possibilties because it made a complex project so much simpler. But I wont try to convert you, you’ll see for yourself as i use it in my project if you think it is usefull...
Thanks.

@cvp here an example of a very simple event class i found on google and modified for my needs. I also added an example of usage.

class EventHook(object):

    def __init__(self):
        self.__handlers = []

    def __iadd__(self, handler):
        self.__handlers.append(handler)
        return self

    def __isub__(self, handler):
        self.__handlers.remove(handler)
        return self

    def __call__(self, *args, **keywargs):
        for handler in self.__handlers:
            handler(*args, **keywargs)

    def clearObjectHandlers(self, inObject):
        for theHandler in self.__handlers:
            if theHandler.im_self == inObject:
                self -= theHandler
                
if __name__ == '__main__':
  class Watcher():
      def __init__(self):
          self.incoming = EventHook()
          self.leaving = EventHook()
  
  class Greeter():
    def __init__(self,me):
      self.me = me
    def sayHello(self, name):
      print('{}: hello Mister {}'.format(self.me,name))
    def sayGoodbye(self, name):
      print('{}: goobye Mister {}'.format(self.me,name))
      
  class Maid():
    def __init__(self,me):
      self.me = me
    def sayHello(self, name):
      print('{}: hello Mister {}'.format(self.me,name))
    def sayGoodbye(self, name):
      if name != 'DSK':
        print('{}: goobye Mister {}'.format(self.me,name))
      else:
        print('{}: You f... s.. o. a b...!'.format(self.me))
  
  from console import clear
  clear()
  Isee = Watcher()
  deskMan = Greeter('desk man Georges')
  maid = Maid('maid Sandra')
  
  # make the connections:
  Isee.incoming += lambda name: print('\nM. {} is comming...'.format(name))
  Isee.incoming += deskMan.sayHello
  Isee.incoming += maid.sayHello
  
  Isee.leaving += lambda name: print('\nM. {} is leaving...'.format(name))
  Isee.leaving += maid.sayGoodbye
  Isee.leaving += deskMan.sayGoodbye
  
  # remove listener from the event
  
  # fire event
  Isee.incoming('Clinton')
  Isee.leaving('Clinton')

  

@cvp excellent! thanks.
It is nice to have the function in a really small piece of code.
I had to limit the number of photos because i have 1600 and that crashes my app. I’ll manage that.

Another thing: for the interractions between panels i learned (from coding in Codea) that it is much easier to wire things together via a register/trigger message system. Do you have something available?
