I'm pretty new to python and kivy and I'm trying to build my first app for my masterthesis. The problem I'm struggeling with right now is that I have multiple python and kivy files, and my app includes a group of Toggle buttons and Spinners. I want to 'store'/assign theselected values and print them when i hit my submit button. I'm working with multiple python and kivy files. The app also has some sliders and i managed to get those values when pressing submit, but can't figure it out for toggles nor spinners. I hope you can help!:)
Main .py, rather important:
import kivy
from kivy.app import App
from kivy.uix.button import Label
from kivy.uix.widget import Widget
from kivy.uix.textinput import TextInput
from kivy.lang import Builder
from kivy.uix.anchorlayout import AnchorLayout
from kivy.uix.boxlayout import BoxLayout
from kivy.properties import BooleanProperty
from kivy.properties import ObjectProperty
Builder.load_file('Header.kv')
Builder.load_file('Statusbar.kv')
Builder.load_file('Inputparameters.kv')
Builder.load_file('Outputparameters.kv')
#Layout
class Peenomat(AnchorLayout):
def show_selected_value(self, spinner, text):
print(spinner, text)
#pass
#DropDown in Inputparameters
#class InputParameters(BoxLayout):
#state = BooleanProperty(False)
class PeenomatApp(App):
def build(self):
return Peenomat()
if __name__=="__main__":
PeenomatApp().run()
The main kv file:
AnchorLayout:
anchor_x: 'left'
anchor_y: 'bottom'
GridLayout:
cols: 1
canvas.before:
Color:
rgba: 0.75 ,0.75, 0.75, 1
Rectangle:
pos: self.pos
size: self.size
Header:
id: _header
size_hint: 1, 0.1
#height: 100
InputParameters:
id:_input_parameters
size_hint: 1, 0.45
StatusBar:
id:_status_bar
size_hint: 1, 0.1
#height: 50
OutputParameters:
id:_output_parameters
size_hint: 1, 0.35
The .kv file that includes the toogle buttons, spinners, and sliders where i guess most of the implemantation needs to be done

The .kv file that includes the submit button:
#: import statusbar StatusBar
<StatusBar@BoxLayout>
orientation:'horizontal'
padding: 5
fs: 16
Button:
text: 'Clear'
background_color: 0.0, 0.353, 0.663, 1.0

size_hint: 0.4, 1
bold: True
font_size: 20
on_press: root.btn_submit()
and last but not the least the file that includes the methods that are assigned to the buttons, which shuld also be important for my issue:
from kivy.uix.boxlayout import BoxLayout
from kivy.properties import ObjectProperty
from kivy.app import App
from kivy.lang import Builder
class StatusBar(BoxLayout):
group_mode = False
#translation = ListProperty(None)
prozess = ObjectProperty(None)
vorbehandlung = ObjectProperty(None)
material = ObjectProperty(None)
haerte = ObjectProperty(None)
rauheit = ObjectProperty(None)
def btn_submit(self,text):
ip = App.get_running_app().root.ids._input_parameters
print("Haerte:", ip.haerte.value, "Rauheit:", ip.rauheit.value, "Material:", ip.material.text)
def btn_clear(self):
np = App.get_running_app().root.ids._input_parameters
np.prozess1.state = "normal"
np.prozess2.state = "normal"
np.prozess3.state = "normal"
np.material.text = "Auswahl treffen"
np.haerte.value = 55
np.rauheit.value = 5.5
The App is running like this and the clear button is exactly doing what its supposed to do, but I really can't figure out how I manage to print the selected spinner and toggle values when hitting submit...I hope you guys can help, been struggeling with this since a while now. Thanks in advance!
Alright i figured out an easy way to get the spinner value when hititng submit:
def btn_submit(self):
ip = App.get_running_app().root.ids._input_parameters
print("Haerte:", ip.haerte.value, "Rauheit:", ip.rauheit.value, "Material:", ip.material.text, "Vorbehandlung:", ip.vorbehandlung.text)
to get the value of the toggle buttons i did this:
def on_state(self, togglebutton):
tb = togglebutton
if tb.state == 'down':
self.verfahren = tb.text
InputParameters.verfahren = tb.text
print(self.verfahren)
return InputParameters.verfahren
and added in the .kv file for the toggle button:
ToggleButton:
id:_prozess2
text:'E-MOH'
on_state: root.on_state(self)
I'm getting the value/state like that, but it's not triggered with the submit button, can't figure out how to do so
