If I have a function that is a button action and the button action takes another function that requires parameters. How do I feed the parameters to the function inside of the button action?
def info_page(sender):
page_info(text, image, dwell_time, desc)
So when I do ....
Btn.action = info_page
How do I feed the parameters to the page_info inside of info_page?
@resserone13 if I correctly understand, what happens rarely these last times:
import ui
def page_info(text, image, dwell_time, desc):
print(text, image, dwell_time, desc)
def info_page(sender):
page_info(sender.prm_text, sender.prm_image, sender.prm_dwell_time, sender.prm_desc)
Btn = ui.Button()
Btn.background_color = 'white'
Btn.prm_text = 'xxx'
Btn.prm_image = ui.Image.named('emj:Airplane')
Btn.prm_dwell_time = 23
Btn.prm_desc = 'abcde'
Btn.title = 'tap me'
Btn.action = info_page
Btn.present('sheet')
@resserone13, or using standard library functools.partial, which is a really good thing to have in your toolbox for any Python coding.
from functools import partial
import ui
def page_info(text, image, sender):
print(text, image, sender.title)
btn = ui.Button(
background_color='white',
title="Tap me",
)
btn.action = partial(page_info, 'some text', 'some image')
btn.present('sheet')
@mikael I knew partial but I didn't know we could use it as action. Marvelous language
@mikael and @cvp Thanks for the help as always. I ended up using the @cvp suggestion. I’m redoing the personal protective equipment app using the ui module instead of scene. Coming along well.

@resserone13 first of all, to avoid repetitive code, you could create your own class with, as parameters, varying infos, here l_txt and tv_txt

self.background_color=bg_color
title = ui.Label()

@cvp ok be been trying to do more of that. That why I have the page_info(). I need to make a few more classes to cut down on the code.
How can I make the text on the links page be able to receive touches and take the user to the websites.
@resserone13 I was busy to understand your loop/path in page_info. What is its goal?
@resserone13 said:
take the user to the websites
How do you want to "take the user to a website"?
Open Safari or have a web view in your ui?
Easiest way is to have, instead of a textview, a button and it's action to open the url
@cvp page_info() is like any_scene() class I used when I made the app with scene. I modeled page_info() after any_scene(). Page_info() is a generic function to display the page. Kinda like your myview().
I’ve also created make_btn() and make_title() for making buttons and creating titles.
@resserone13 I would like them to be directed to the website in Safari.
@resserone13 written just before your answer about safari, this code opens a web view in your app.
If you open safari, you will leave your app. Sure of this?

@cvp the imported file ppeasy_text.py is in the same folder as the main.py file.

@resserone13 I understand but it is not in your GitHub, for testing your code 😀
@resserone13 did you try my code to open a web view?

Your rectangle has a width of 0, thus not displayed...
@resserone13 and path can be drawn in the draw method of the ui.View, but, it seems, only if you sub-class it.
class View_with_Path(ui.View):
def draw(self):
for x, y in (screen_size.w/2, screen_size.h * 0.8), (screen_size.w/2, screen_size.h * 0.4), (screen_size.w/2, screen_size.h * 0.1):
path = ui.Path.rounded_rect(x, y, screen_size.w * 0.8, 10, 50)
path.line_width=3
ui.set_color('yellow') # only to see where the path is drawn
path.fill()
def page_info(text, image, dwell_time, desc):
v = View_with_Path()
#v = ui.View()
v.frame = (0,0,screen_size.w,screen_size.h)
v.background_color=bg_color

@resserone13 said:

If you prefer to open really Safari:
if tv_txt.startswith('http'):
tv = ui.Button()
tv.title = tv_txt
def open_url(sender):
import webbrowser
webbrowser.open('safari-'+sender.title)
@resserone13, things are moving so fast here that I am probably hopelessly late, but I can think of two options if you want to have clickable links in the middle of a body of text.
First is to use a webview, which works but has the downside that it wants to open the link in place. You can get around this by using a delegate to capture the attempt and open the link in Safari instead.
Second is to use objc and attributed text with a textview or label. This is not difficult but can be made even easier with an addition to the RichLabel that is part of the ui3 package, let me know if that seems relevant to you.
@mikael I just have my iPhone 11 with Pythonista. I don’t know if I have ui3. I’ve had trouble using stash to import and pip install modules. The web view is working OK for me. I just need to add some navigational buttons at the top. But it does look nice. I will probably have questions on objc In the near future. Once I figure out UI I will dive into objective c.
@cvp. Thanks for all your input and advice. I am reviewing everything and re-writing the script. Hopefully everything will be functions. I am going to try classes as well but I might have mainly functions. I’m going to work on it and I will keep you updated. Thanks for all your help it’s really allowing me to get a lot done and learn a lot. Hopefully when I keep showing you these updates you’ll see that I’m learning from what you’re showing me.

I have a for loop that loops over btn names and creates a button for each name. How do I make it loop over a list of btns and a list of actions so that the each button gets a name and an action?
I’m using enumerate to help space the btns out. I tired switching to zip but then I loose the i variable for the enumerate function?
def add_btn(self, btn_names, actions_list):
for i, name, a in enumerate((btn_names)):
btn= ui.Button()
btn.background_color=btn_clr
btn.title=name
btn.font=(btn_fnt, btn_txt_sz)

self.add_subview(btn)
@resserone13 something like (not tested):
def add_btn(self, btn_names, actions_list):
for i in range(len(btn_names)):
btn = ui.Button()
btn.name = btn_names[i]
btn.action = actions_list[i]
range(len())is almost always a sign to use enumerate()instead.
import ui
def show_sender(sender):
print(sender.title)
class MyView(ui.View):
def __init__(self):
self.add_buttons("abc", (show_sender, show_sender, show_sender))
def add_buttons(self, titles, actions):
width = self.width
height = self.height
for i, (title, action) in enumerate(zip(titles, actions)):
button = ui.Button(
title=title,
action=action,
background_color="pink",
border_color="dark green",
border_width=2,
corner_radius=5,
font=("system", 12),
tint_color="grey",
)
button.frame = (width * 0.1, height * (0.1 + i), width * 0.8, height * 0.8)
self.add_subview(button)
MyView().present()
@resserone13, maybe clearer and less error-prone is to pair the titles and actions when calling the method:
class MyView(ui.View):
def __init__(self):
self.add_buttons(
("A", action_a),
("B", action_b),
)
def add_buttons(self, *args):
width = self.width
height = self.height
for i, (title, action) in enumerate(args):
button = ui.Button(
title=title,
action=action,
...
Thanks @cvp @ccc and @mikael for the help. I was able to get past the hang up and move forward on the app development. I ended up using @ccc suggestion because i was using code very similar to what I already had. I’m finishing up a few more things then I will post on GitHub.
