It's my first program for Pythonista

Cheng

It use in widget.
1.get date in a json file
2.get date from datetime
3.If the two dates are the same, read the json file，else update the json file and read it.
4.put the result in widget.

I am a newbie, please advise.

And I want to ask how to display multiple buttons in the widget and can turn pages？

    data = get_page(url)
    write_file(data)
    layout()

def get_page(url):
    return requests.get(url, headers=headers).json()

@Cheng you have to use v instead of text as widget_view

appex.set_widget_view(v)

and add buttons as subviews of v, like you did with textview

Cheng

@cvp Thank u.
Can you give me an example with the following code?
In a widget display both button1 and button2.

v = ui.View()
button1 = ui.Button(title='button1')
button2 = ui.Button(title='button2')
v.add_subview(button)
appex.set_widget_view(v)

brumm


button1.frame = (x, y,width,height)
button2.frame = (x, y,width,height)

v.add_subview(button1)
v.add_subview(button2)

Cheng

@brumm I succeeded
I didn't set the position when I tried it, the second button blocked the first button.
Thank U.

cvp

@Cheng you are right, and you made a little error with add_subview(button) instead (button1) and (button2)

mikael

@Cheng, for paging, how long are your lines?

Cheng

@mikael I plan to do less than 50 lines.
Each button is actually a hyperlink that allows browse the web in the widget.That's my idea.

Cheng

And another problem is Button.action
The function must take a single sender parameter.
I want different buttons to correspond to different links.

ccc

def button_action(sender):
    if sender.title =="Apple":
        url = "https://www.apple.com"
    elif sender.title =="Google":
        url = "https://www.google.com"

Cheng

@ccc there’s many links in a file, Function cannot pass variables.

ccc

The button (sender) has attributes... Here I used sender.title but you could also add a .url attribute to your buttons...

button1.url = "https://www.apple.com"

cvp

@ccc "les grands esprits se rencontrent" 😂, I just wrote

import ui
v = ui.View()
v.frame = (0,0,200,200)
def b_action(sender):
	print(sender.url)
b1 = ui.Button(title='Apple', frame = (10,10,80,32), url='https://www.apple.com', action=b_action)
v.add_subview(b1)
b2 = ui.Button(title='Google', frame = (100,10,80,32), url='https://www.google.com', action=b_action)
v.add_subview(b2)
v.present('sheet')

Cheng

@ccc my button url is a variable.

def button_tapped(sender):
	self.webbrowser.open(href) #？？？
v=ui.View(frame=(0,0,300,400))
with open('./wb.json', 'r') as f:
	wb = f.readlines()
	for i in range(0,20):
		wbi = wb[i]
		title = json.loads(wbi)['title']
		href = json.loads(wbi)['href']  #href is the button url
		button = ui.Button(title=title)
		button.action = button_tapped 
		button.frame = (0,i*25,450,20)
		v.add_subview(button)

I think I need 20 button.tapped functions.

ccc

Do you use GitHub? A repo with more complete code would help a lot. You definitely do not need 20 actions.

cvp

@Cheng I'm sure @ccc will answer in one minute, thus...😀

cvp

@Cheng when you create your buttons, set

button.href = href

and you want to use it, in action, do

.......open(sender.href)

Cheng

I’ll try.
Thank you @ccc and thank @cvp .
Also thanks to Google Translate.😅

cvp

@Cheng Sorry for the French sentence, it was only a joke for @ccc
