[Share] A unique set of attrs from the combination of all ui Elements

[Phuket2]

Not ground breaking. But can be nice to see/have a list of every unique attr used across all the ui elements/controls. pprint is used to give a nice print out(sorted). Also, nice to see how easy it is when you get sets to do the heavy work.

Anyway, I wanted this for a lib I am doing, so I thought I would share the portion.

'''
	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 imthink 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.

@Phuket2, Thank you! I have been looking at a few of your examples and I really appreciate your contributions!

This example made me want to be able to get all the attributes of specific ui elements, so I put something together real quick based off of your code..

import ui, pprint

items = [
	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
	]

def show():
	iitems = enumerate(items)
	for x in iitems:
		print(x)

def all():
	for a in items:
		pp.pprint((a,dir(a)))
		
def one(i):
	a = items[i]
	pp.pprint((a,dir(a)))
	
pp = pprint.PrettyPrinter(indent=3, width=46)


ins='show() displays the ui elements,\nall() prints all attrs of all ui elements,\none(i) prints attrs of element i where i is the elem number (as shown by show())'
print()
show()
print()
print(ins)

@dgm , nice short cuts. But normally your functions would return something rather than print. Or pprint. But you could turn this into a very functional class.
