How to add TextInput text to a label in python kivy?

I'm making an app in python kivy, and I have 2 draggable Images in my "TacScreen" and whenever I double tap on either of them It opens up a popup, inside the popup I have a Textinput field where I can input text. Whatever text I put in there I want that to show inside a Label below my Draggable Image. The problem that I'm facing now is when I type anything in the text input field and press the close button (you can see it below in my code) It closes the popup and I don't see any text. How can I fix this? Below is my code!

Kivy Python | Position TextInput

I would like to position my TextInput (i.e. the field) to the left of the but I cannot do this:

I recommend rearranging your gui in kv scrpit.
Replace
Label:
...
TextInput:
...
with
BoxLayout:
orientation:'horizontal'
Label:
...
TextInput:
...

How to clear the text field after performing??? KivyMD

After performing an operation, for example, receiving text and closing the window, when opening the window in the text field text.
It is necessary that after closing the mdDialog window, the text is erased. I manage to save it, but in the string method. It must be erased by pressing the button and closing.

Good day.
I recommend you create text_field_text = StringProperty("My Default String") in your App class and let the widget.text = app.text_field_text.
From there, you could clear your app string property with the callback function.

Kivy - How to access instance of class created by .kv file?

My class OrderManagementScreen is firstly instantiated by Builder.load_file and then by sm.add_widget(OrderManagementScreen(name='order_management')).
I would like to be able to access the instance created by Builder.load_file - how can I do this?
This post is the closest I could find, but when I do MDApp.get_running_app().root it returns None.
app.py: (mixture of attempts in my update_database function)
import atexit
from kivymd.app import MDApp
from kivy.lang import Builder
from kivy.uix.screenmanager import Screen, ScreenManager
from order_management.constants import HELP_TEXT
from order_management.presentation.order_management.order_management_view import OrderManagementScreen
from order_management.presentation.components.dialog import Dialog
from order_management.data.query import Query
class App(MDApp):
def __init__(self, **kwargs):
super().__init__(**kwargs)
self.screen = Builder.load_file(
"order_management/presentation/main.kv")
self._query = Query()
something = MDApp.get_running_app()
self._dialog = Dialog()
def build(self):
self.theme_cls.primary_palette = "Green"
sm = ScreenManager()
# Instantiates OrderManagementScreen.py
sm.add_widget(OrderManagementScreen(name='order_management'))
return self.screen
def handle_menu_click(self):
self._dialog.render_dialog("Usage Guide:", HELP_TEXT, None, None)
def update_database(self):
# order_management_screen = MDApp.get_running_app().screen.children[0].manager.get_screen('order_management')
# order_management_screen = self.screen.get_screen('order_management')
self.order_management_screen.update_database()
if __name__ == "__main__":
App().run()
main_app = App()
atexit.register(main_app.update_database) # Calls update_database on exit.
main.kv:
#:kivy 1.11.0
#:include order_management/presentation/order_management/order_management_ui.kv
# Having to use v1.11.0 because of bug relating to MDDataTable
<Toolbar#AnchorLayout>:
AnchorLayout:
anchor_x: 'center'
anchor_y: 'top'
MDToolbar:
title: 'Order Management App'
specific_text_color: app.theme_cls.accent_color
right_action_items: [['help-circle', lambda x: app.handle_menu_click()]]
elevation: 9
ScreenManager:
OrderManagementScreen:
Toolbar:
order_management_ui.kv:
#:kivy 1.11.0
# Having to use v1.11.0 because of bug relating to MDDataTable
<OrderManagementScreen>:
name: 'order_management'
id: order_management
GridLayout:
cols: 1
pos_hint: {'top': 0.85}
ScrollView:
id: table_container

I guess it goes to show how sometimes you just need to step away from the computer and come back with fresh eyes...
My solution was to simply store the instance of app when run so that when I called my update_database function is was looking at the correct instance - and therefore could access the instance of a screen class the kivy had created with:
self.root.children[0].manager.get_screen('order_management')
I use children[0] here because this is the first screen I added to ScreenManager, and 'order_management' is the name of the screen obviously.
I hope that this by chance does help someone else.
New app.py:
import atexit
from kivymd.app import MDApp

from kivy.uix.screenmanager import Screen, ScreenManager
from order_management.constants import HELP_TEXT

from order_management.presentation.components.dialog import Dialog
from order_management.data.query import Query
class App(MDApp):

def update_database(self):
order_management_screen = self.root.children[0].manager.get_screen('order_management')
order_management_screen.update_database()

kivy python List to button text

Trying to populate the text of three buttons with the content of myList["One", "Two", "Three"]
btn1 = myList[1] etc
myList will be populated fron csv file
from kivy.app import App
from kivy.lang import Builder
kv = """
BoxLayout:
Button:
id: btn1
Button:
id: btn2
Button:
id: btn3
"""
class TestApp(App):
def build(self):
my_box = Builder.load_string(kv)
my_ShowList = ['My Way', 'Wine Drinker', 'Boots']
'''
This is where I get lost
want to use for loop to populate Button text with my_ShowList items
'''
return my_box
if __name__ == '__main__':
TestApp().run()enter code here`

You can do it entirely in python code:
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.button import Button
class TestClass(App):
def build(self):
my_box = BoxLayout()
my_show_list = ["My Way", "Wine Drinker", "Boots"]
my_box.my_buttons = [] # if you want to keep an "easy" reference to your buttons to do something with them later
#kivy doesnt crashes because it creates the property automatically
for message in my_show_list:
button = Button(text=message)
my_box.my_buttons.append(button)
my_box.add_widget(button)
return my_box
if __name__ == "__main__":
TestClass().run()

This should solve this problem:
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.button import Button
class MyLayout(BoxLayout):
def __init__(self, **kwargs):
super(MyLayout, self).__init__(**kwargs)
self.btn_list = ['My Way', 'Wine Drinker', 'Boots']
for btn_text in self.btn_list:
self.add_widget(Button(text=btn_text))
class MyApp(App):
def build(self):
return MyLayout()
if __name__ == '__main__':
MyApp().run()
