Containers for photos, with scroll, drag&drop between them
-
@cvp thanks for the 2nd example, it is inspiring.
Actually i dont use grids i prefer to place and zoom and cut each photo manually.
If you put your whole program in github i certainly wont demand support!
I think I’ll post my work step by step in gists and this forum as I progress. Not sure how fast I’ll go though...
Btw, I am french too (Grenoble) so no pb with the langage. I’ll continue anyway to write in english by respect for people in this forum.
Thanks.

@cvp from the doc, it seems the tableView is vertical only. Is there a way to have is horizontal too? Initially i wanted my camera roll container to be vertical, but the photo group containers to be horizontal (and themselves inside a scrollable vertical container too).
So i should pbly use a scrollview instead for my base photo container? -
@cvp mmm PhotosPickerView.py seems a bit over my head, with all this objC functions...

It is not so complex as it seems...

@cvp thanks for juxtapositionDePhotos.py
all the bricks i need are there
=> this is really going to help me.
thanks. -
@jmv38 quick and dirty horizontal scroll view
import photos import ui def main(): assets = photos.get_assets() #assets = photos.pick_asset(assets=assets,multi=True) d = 100 wsv = min(400,d * len(assets)) sv = ui.ScrollView() sv.frame = (0,0,wsv,d) x = 0 for i in range(0,len(assets)): b = ui.Button(name=str(i)) #b = ui.ImageView(name=str(i)) b.border_color = 'blue' b.border_width = 1 ui_image = assets[i].get_ui_image().with_rendering_mode(ui.RENDERING_MODE_ORIGINAL) w,h = ui_image.size w = d * w/h b.frame = (x,0,w,d) b.image = ui_image def b_action(sender): sender.superview.name = 'tapped=' + sender.name b.action = b_action sv.add_subview(b) x = x + w sv.content_size = (x,d) sv.present('sheet') if __name__ == '__main__': main()

@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?

No, never done like that. I always use normal way of ui. Good luck

@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')

@jmv38 Too complex for me 😀
-
@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 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. -
@jmv38 did you try ui.RENDERING_MODE_ORIGINAL
-
@jmv38 this is ok, I think
img = ui.Image('iow:refresh_32')#.with_rendering_mode(ui.RENDERING_MODE_ORIGINAL) b.image = img b.tint_color = 'gray'
-
@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 you know what? it works with ORIGINAL
looks like omz inverted TEMPLATE and ORIGINAL values
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.
