How do i add a signature/paint method to a screen in my app in either kv lang or normal kivy?

how do i add buttons to my paintScreen class without the on_touch_down/move interfering and making it so that i draw within a BoxLayout canvas and separate the buttons in a different box so that it wont draw over the buttons? This is the current problem i am having. Also if that problem is fixed then would i be able to save that drawing as an img if i use export_to_png

A person is supposed to enter the Password 'gin' than click on a button 'NEXT' to go to the next screen named SecondWindow , then click on a button 'NEXT' to go to the next screen named TherdWindow ,
Then enter a First Value in the Box then click on a button 'NEXT' to go to the next screen named fourWindow ,
than enter the second Value and click on a button 'NEXT' to go to the next screen named funfthWindow .
there should have the 'Result' if he click on a button result. In this screen there is a Label that should print the volume of the sum that the person specified.

When I click of 'Result' I get this Error NameError : first_Value is not defined
please help. I would really appreciate any advice.

Well, there's a lot of ways to do that, for the simplicity I'll do all operations in the MyMainApp class:
from kivy.properties import ObjectProperty
from Kivy.clock import Clock
...
class Therdwindow(Screen):
first_Value = ObjectProperty(None)
def getvalue(self):
return self.first_Value
class Fourwindow(Screen):
second_Value = ObjectProperty(None)
def getvalue(self):
return self.second_Value
class FunfthWindow(Screen):
label_id = ObjectProperty(None)
def getlabel(self):
return self.label_id
class WindowManager(ScreenManager):
pass
class MyMainApp(App):
def build(self):
with open('layout.kv', encoding='utf-8', errors='ignore') as f:
Builder.load_string(f.read())
# creating objects of screens
self.mainwindow = MainWindow()
self.secondwindow = SecondWindow()
self.therdwindow = Therdwindow()
self.fourwindow = Fourwindow()
self.funfthwindow = FunthWindow()
# creating object of screen manager
self.sm = WindowManager()
# getting all object properties
self.first_Value = self.therdwindow.getvalue()
self.second_Value = self.fourwindow.getvalue()
self.label_id = self.funfthwindow.getlabel()
# connecting object properties to widgets from kv file
# sometimes we need to delay that, because the app can't load so quickly, so let's make a method for it
Clock.schedule_once(self.getids)
# adding screens to screen manager
self.sm.add_widget(self.mainwindow)
self.sm.add_widget(self.secondwindow)
self.sm.add_widget(self.therdwindow)
self.sm.add_widget(self.fourwindow)
self.sm.add_widget(self.funfthwindow)
# in case you want screen manager be able to work you should return it
return self.sm
def getids(self):
self.first_Value = self.therdwindow.ids.first_Value
self.second_Value = self.fourwindow.ids.second_Value
self.label_id = self.funfthwindow.ids.label_id
# method that does what you want
def count(self):
self.label_id.text = str(int(self.first_Value.text) + int(self.second_Value.text))
if __name__ == "__main__":
MyMainApp().run()
And you need to edit your kv file, change all that
on_press:
app.root.current = "second"
to that:
on_press:
app.sm.current = "second"
And change this:
CustButton:
text: "Result : "
font_size: "30sp"
on_press:CalcmGridLayout.calculate3(first_Value.text,second_Value.text)
to this:
CustButton:
text: "Result : "
font_size: "30sp"
on_press: app.count
Also you need to add that lines in classes:
<Therdwindow>:
...
first_Value: first_Value.__self__
<Fourwindow>:
...
second_Value: second_Value.__self__
<FunfthWindow>:
...
label_id: label_id.__self__
And delete this:
WindowManager:
MainWindow:
SecondWindow:
Therdwindow:
Fourwindow:
FunfthWindow:
Sixwindow:

You are trying to use ids from one rule inside another rule, but ids are only available for the current rule. So, this line in your kv will not work:
on_press:CalcmGridLayout.calculate3(first_Value.text,second_Value.text)
A way to fix this, is to access the ids by first getting the Screen where that id is defined, and that is more easily done outside of kv. So, I would recommend replacing the above line with:
on_press:root.calculate3()
And then rewrite your calculate3() method slightly to access the other values:
class FunfthWindow(Screen):
def calculate3(self):
bibi = App.get_running_app().root.get_screen('therd').ids.first_Value.text
mimi = App.get_running_app().root.get_screen('four').ids.second_Value.text
kiki = str(float(bibi) + float(mimi))
if kiki:
try :
self.ids.label_id.text = str(eval(kiki))
except Exception:
self.ids.label_id.text = 'Error'

errors in results after launching program

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

How should I set a global variable in kivy Python?

My application is simple, the ScreenTwo is showing a form 'Parametreur' with various options to be entered.
What I'm trying to do is to set a 'save' button at the end of this form that will register into a list called 'resultat' all the options furfilled so far leaving '0' in the empty inputs.
The global variable 'resultat' would look like this ['blabla','15/06/2018','31/12/1999','6'].

Where and How should I set my global variable 'resultat' (which is a list)?
I've solved my problem but I still don't understand how does it work. Setting a variable is Kivy doesn't need to set it in the Python code. But how do Kivy and Python know about its type? Right now, it works as a list without me defining it such as (I intended it to be a list anyway).
How could I set a variable as tuple for example?
