@Matteo If you use the DirAllTheGlobals approach, you can avoid using double underscores, though might still need to set sys.modules['main'].varname from r anythingyou want to save from within startup itself.

There is another option, which is to disable global clearing, using @dgelessus 's pythonista startup

see
https://github.com/dgelessus/pythonista_startup/blob/master/init.py

and uncomment the section indicated. This replaces the pythonista_startup with a fake module that lists all globals, thus preventing clearing.

There are a few posted on Pythonista Tools.
Do you have a repo? I think you might find people willing to contribute.

Google Chrome has started distrusting ssl certificates issued by symantec, rapidssl, and others, before a certain date. These forums are now basically inaccesible on android using the latest Chrome.

Apparently you can get a free "upgrade" to your certs:

you just want to use begin_editing() on your textfield or textview afte you present it. It not in the docs, so don't feel bad you missed it .

To set tab order requires a but more effort-- see:

https://forum.omz-software.com/topic/4562/set-next-field-for-tab/12

For your other question, you can either walk your way up and down the view heirarchy
sender.superview.superview['panel']['label5']
or, when you set up your textfield, or button, or whatever, you could add an attribute with some key piece of info

textfield=ui.Textfield()
mainview.addsubview(textfield)
textfield.target=label
textfield.action=textfieldaction
...
#elsewhere
def textfieldaction(sender):
   sender.target.title='hello'

alternatively, using a custom view class for your main view lets you access the mainview via self.

class myview(ui.View):
   def __init__(self):
      self.label =ui.Label()
      self.add_subview(self.label)
....
   def textfield_action(self, sender):
      seld.label.title='hello'

That way, there is one commin place for everything that any ui element needs to know.

This is an updated version of @omz's original, but converted to using create_objc_class so it works in latest version.

Also, I added a delegate method which returns an annotationView, and uses the annotation title to set the image

I suspect the https solves the immediate problem, though eventually we may need to migrate to pypi.org instead of pypi.python.org

I think the old url still redirects to the new..

This probably worked in python 2.7. The string arguments need to be byte instead. The recent objc_util includes create_objc_class, which simplifies the entire class creation process, and handles strong to byte conversions.

fwiw, i always forget this, but divmod lets you do both in one operation:

y,x = divmod(i, 5)

The andhor point just says what part of the node your are placung with position. But the coordinate system of the parent which you place into is always based in the corner. so, if you are trying to create a grid, using corner coordinates probably makes more sense, or else, you need to reference everything to the center, and use vector addition.

i.e

center=parent.bbox.size/2.0 #(w/2, h/2)
somenode.position = center + Vector2( j*colwidth, i*rowheight)

where i,j are row/col, as measured from the center.
