I can print value from images.kv but I can't find how to print the values of two TextInputs when a button is pressed.
This is the first time I have posted so I have a lot of mistakes. Thanks if I can get any help from everyone.
I'm a physicist, and as everyone knows, we like our cocktails. I am therefore trying to build an automatic bartender. Unfortunately, the only experience I have with programming in python is to do physics simulations, and I am not that savvy with coding anyways.
My problem is now this: there is a python list in the class BartenderApp that I want to use in the kivy file, specifically in the LoadNewIngredients in the kivy file, for the spinners to take their options from. I have looked quite a while for a solution and none have worked so far. I know I should be able to put the spinners and labels in the python file using a for loop, but I would much rather have it a bit more clean and keep them in the kivy file.
So if anyone could help me how to pass the list to the kivy file, it'd be much appreciated!

Try adding a ListProperty (https://kivy.org/doc/stable/api-kivy.properties.html) to you App class. Like this:
class BartenderApp(App):
ingredients = ListProperty()
for drink in range(len(drink_list)):
ings = list(drink_list[drink]['ingredients'].keys())
for ing in range(len(ings)):
elem = ings[ing]
if elem not in self.ingredients:
self.ingredients.append(elem)
A list property is both accessible in the Python and KV file. What's more is that they can be bound to a callback so that you can create your own event!
In the KV file you can now refer to app.ingredients and any object that is defined by the list will be automatically updated when app.ingredients is changed. So for example if you had the following label in your KV file:
Label:
text: app.ingredients[0]
The text would automatically update when you change the list. Be careful though, you may get an index error if there isn't an object in the index you're referencing.
Let me know how you get on with this and whether it solves your problem.
I finally managed to solve it, maybe not the best solution, but it works.
In the class LoadNewIngredients I wrote a function that checked what ingredients are available and returns a list with the ingredients. This function is then referenced in the kivy app using root.function_name().

Hopefully this helps if someone else has the same problem.
But if anyone has any other solutions (or suggestions about the code in general), please let me know!
this is my 1st time posting here and am so amazed how genius people here are.
i have written a python code using kivy and it works perfectly on my computer even on kivy launcher for android, but the problem is that the result on my phone is always ignoring the float numbers and show just the 1s one.
thanks in advance

Let's imagine we have a form where the person wrote some stuff on the inputs but need to clear them all, how would I do that in Kivy?
I tried this but it didn't work:
main.py:
class CreateUra(GridLayout):
def clear_inputs(self, *args):
for item in args:
item = ''
class UraApp(App):
def build(self):
return CreateUra()
if __name__ == "__main__":
UraApp().run()

padding: 10
spacing: 10
row_force_default: True
row_default_height: '32dp'
BoxLayout:
Label:
text: 'Contexto:'
TextInput:
hint_text: "Contexto da ura"
focus: True
multiline: False
cursor_color: (0, 0, 0, 0.8)
id: context_input
BoxLayout:
Label:
text: 'Nome da ura:'
TextInput:
hint_text: "Nome do arquivo da ura"
multiline: False
cursor_color: (0, 0, 0, 0.8)
id: ura_file_name
Button:
text: 'Create Ura'
id: bt_create
on_press: root.uraConfig()
on_release: root.clear_inputs(context_input.text, ura_file_name.text)
*Ignore the uraConfig on the on_press
I tried this way and it worked:
Button:
text: 'Create Ura'
id: bt_create
on_press: root.uraConfig()
on_release: context_input.text = ''
I'm quite new to kivy and Python, so I'm not sure if this was the best way to clear the texts, but what I did wrong? Or if you guys could give some light in the best way to do it.
The problem in your case is passing the text, but not text property but a copy of the text, so even if you set it to empty is not reflected in the textinput. You have to pass the textinput as a list, iterate and set the property with an empty string:
*.kv
Button:
text: 'Create Ura'
id: bt_create
on_press: root.uraConfig()
on_release: root.clear_inputs([context_input, ura_file_name]) # <-- add brackets
*.py
class CreateUra(GridLayout):
def clear_inputs(self, text_inputs):
for text_input in text_inputs:
text_input.text = ""
I tried this and it work for me:
*kv
TextInput:
id: my_text_input
hint_text: "Your name..."
size_hint: None, None
height: "50dp"
width: "100dp"
multiline: False
on_text_validate:root.on_text_validate(self)
Label:
id: txt
text: "Your name is: " + root.text_input_str
Button:
text: "Reset details"
on_press: root.on_button_reset_details()
size_hint: None, None
width: "100dp"
height: "50dp"
*py
class WidgetGalaxy(GridLayout):
text_input_str = StringProperty("")
def on_text_validate(self, widget):
self.text_input_str = widget.text
def on_button_reset_details(self):
self.text_input_str = ""
self.ids.my_text_input.text = ""
if self.ids.my_text_input.text == "":
self.ids.my_text_input.hint_text = self.ids.my_text_input.hint_text
with all that it should work for your code...
If having issue check your code preference and some predefined local or global variable.
I have a basic app in Kivy with a class for each screen. I would like to have the user enter some text in one screen and for this to be displayed in a label on another screen.
I've been through all the similar posts but can't seem to get anything working.
The two classes EnterSentences and Review have ObjectProperties. Is there a way to connect these with bind? Or do I need to just structure things completely differently?
Any help much appreciated. Here's the .py file
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.properties import ObjectProperty
class MainMenu(BoxLayout):
def enter_sentences_button(self):
self.clear_widgets()
self.add_widget(EnterSentences())
def review_button(self):
self.clear_widgets()
self.add_widget(Review())
def settings_button(self):
pass
class EnterSentences(BoxLayout):
search_box = ObjectProperty()
def main_menu(self):
self.clear_widgets()
self.add_widget(MainMenu())
class Review(BoxLayout):
sentence = ObjectProperty()
class NewApp(App):
pass
if __name__ == "__main__":
NewApp().run()
and the .kv file:
MainMenu
<MainMenu>:
orientation: 'vertical'
Label:
text: "Welcome to your Flash Card App!"
size_hint_y: 5
BoxLayout:
size_hint_y: 1
orientation: "horizontal"
Button:
text: "Enter sentences"
on_press: root.enter_sentences_button()
Button:
text: "Review"
on_press: root.review_button()
Button:
text: "Settings"
<EnterSentences>:
search_box: enter_sentence
orientation: "vertical"
Label:
text: "Enter your sentences here:"
size_hint_y: 4
TextInput:
id: enter_sentence
TextInput:
TextInput:
BoxLayout:
orientation: 'horizontal'
Button:
text: 'Main Menu'
on_press: root.main_menu()
Label:
text: ''
<Review>:
orientation: 'vertical'
Label:
size_hint_y: 4
text: root.search_box
TextInput:
size_hint_y: 1
You only have to change the kv file. You could add the text from the 3 TextInputs to 3 variables readable from the whole app:
TextInput:
+ on_text: app.sentence1=self.text
id: enter_sentence
TextInput:
+ on_text: app.sentence2=self.text
TextInput:
+ on_text: app.sentence3=self.text
Then you could access the new variables in the Review:
<Review>:
orientation: 'vertical'
Label:
size_hint_y: 4
text: app.sentence1 + "\n" + app.sentence2 + "\n" + app.sentence3
TextInput:
size_hint_y: 1
