This is a re-share. I was looking for something today and come across this. It's just some code to get all unique attrs across all ui elements. Just updated with a nice addition from @ccc. It looks long and bulky. But it's just all the comments and trying to show it easily in my opinion. Below that, I do the same share without comments and condensing the functions. Just to show about sharing. Normally when I share, I don't try to condense everything. I go more for the understanding side of things. Not sure what's better.

    get_all_attrs_set - the main function of interest

    iterates over a list of all the ui Elements, and retuns a set of 
    all the unique attrs for all the ui Elements combined.

    i am sure this could be tighten up more. But i think the readabilty
    is ok now. if not for ui.NavigationView, i would have tried to use 
    a list comp rather than the for. I could have tried to special case
    it, but i think personally this is more clear given what it is.

    This was hard coded before. Have commented it out now. i have left 
    it in just to show the lesson i learnt.  only recently also :(
    @ccc provided the list comp in the func get_ui_classes() that 
    totally negates having to create a static list.

_ui_controls = \
    [
        ui.View, ui.Button, ui.ButtonItem, ui.ImageView, ui.Label,
        ui.NavigationView, ui.ScrollView, ui.SegmentedControl,
        ui.Slider, ui.Switch, ui.TableView, ui.TextField, ui.TextView,
        ui.WebView, ui.DatePicker, ui.ActivityIndicator, ui.TableViewCell
    ]

    # sets doing all the hard work with the union operator '|'

            # ui.View as a param
            if ctl is ui.NavigationView:
                s = s | set(get_full_dict(ctl(ui.View())))
            else:

    pp.pprint(attr_set)
    print('Number of unique attrs across all ui elements (not filtered) - {}'.format(len(attr_set)))
    print()
    print('python 3.5x reports 155 items, python 2.7x reports 149 items. the difference lays in the attrs starting with _')

The same result, just condensed and comments removed.
