How to make list in second screen with kivy

How to make list in second screen with kivy - python

I tried to show the list in my second screen after I click the button in the main screen. but the list won't show but I have no error. is there anything wrong with my kivy code?
this is my code
def rumus_power_np(radius, air_density, efficiency_factor, kecepatan_angin):
return 3.14/2 * pow(radius, 2) * np.power(kecepatan_angin, 3) * air_density * efficiency_factor
class MainWindow(Screen):
def btn(self):
print("name: ",self.radius.text)
predicted_power = rumus_power_np(int(self.radius.text), float(self.air_density.text), float(self.efficiency_factor.text)/100, predictions)
data = {'time': series.date[-109:].dt.time,'power': predicted_power}
df = pd.DataFrame (data, columns = ['time','power'])
plt.plot(df.time,df.power, color='orange', label = 'predicted power')
plt.xlabel("time")
plt.ylabel("power (watt)")
plt.legend()
print(predicted_power)
self.manager.get_screen('second').ids.rv.data = [{'time': df.time}, {'power': df.power}]
class SecondWindow(Screen):
def btndu(self):
self.ids.destination.add_widget(FigureCanvasKivyAgg(plt.gcf()))
class WindowManager(ScreenManager):
pass
kv = Builder.load_file("my.kv")
class MyMainApp(App):
def build(self):
return kv
if __name__=="__main__":
MyMainApp().run()
the predicted_power data exist from code above it and it must have 109 rows from that data.
and this is my kv code

please help me if there is something wrong? Because this is my first time

The keys in your data must be attributes of your viewclass. If you are using Label as your viewclass, then the keys in your data are likely to be text, since that is the attribute of Label that can display a string. You can create your own viewclass to meet your specific needs. I have taken the liberty to create a viewclass that I call DataDisplay to demonstrate what I mean:
class DataDisplay(BoxLayout):
time = NumericProperty(0.0)
power = NumericProperty(0.0)
And using kv to plan the layout of the DataDisplay:
<DataDisplay>:
orientation: 'horizontal'
Label:
text: 'time: ' + str(root.time)
Label:
text: 'power: ' + str(root.power)
In this arrangement, each data element should contain two keys, a time and a power. Using this, the following code will display two sets of time and power in the RecycleView:
class MainWindow(Screen):
def btn(self):
self.manager.get_screen('second').ids.rv.data = [{'time': 2.3, 'power': 4.5}, {'time': 0.1, 'power':9.356}]

Change screen to MainScreen after a countdown(inactivity) in kivy MDApp

I have an App with 3 screens managed by a ScreenManager: MainScreen, ScanScreen, PinScreen. From MainScreen I have 2 buttons, 1 to go to ScanScreen, 1 to go to PinScreen. In ScanScreen I have a button to go into PinScreen and in PinScreen I have a button to go in ScanScreen. I want to go to MainScreen after some interval of time. I managed to make it works only if I go to secondary screens from MainScreen. If I go from MainScreen to ScanScreen and from ScanScreen to PinScreen then it wont work. I get this error:
line 16, in timeout
self.parent.current = 'mainScreen'
AttributeError: 'NoneType' object has no attribute 'current'
This is what I got so far:

I also tried this:

MDApp.get_running_app().root.manager.current = 'mainScreen'
#self.parent.current = 'mainScreen'
def on_enter(self, *args):
Clock.schedule_once(self.timeout, 2)
but I get this error:
MDApp.get_running_app().root.manager.current = 'mainScreen'
AttributeError: 'ScreenManagement' object has no attribute 'manager'

So to clarify, I managed to do what I wanted by using get_running_app() method and accessing the root, which in my case is the ScreenManager. I made some changes to my code so it would reset the countdown after activity. This is what I have in each of the screen that I want to return to MainScreen after 30s of inactivity:
class ScanScreen(Screen):
def timeout(self, *args):
MDApp.get_running_app().root.current = 'mainScreen'
MDApp.get_running_app().root.transition.direction = 'right'
def reset_timeout(self, *args):

Clock.schedule_once(self.timeout, 30)

Clock.schedule_once(self.timeout, 30)
def on_leave(self, *args):
Clock.unschedule(self.timeout)
def on_touch_down(self, touch):
self.reset_timeout()
return super().on_touch_down(touch)
def on_touch_move(self, touch):

Concurrently running a loop with a kivy window

I am trying to build a simple messaging app, that uses rabbitmq as its message broker and kivy as its UI. So to receive incoming messages I have a receive function that is a loop, But when I try to multi-process the app and run it, kivy seems to be opening multiple windows. Kindly advise how I can tackle this issue.

What you are pretending to do is to run kivy concurrently. The best choice for async events in kivy is to use asyncio (as the oficcial documentation suggest). First at all you have to be sure your app runs from asyncio.run() instead of App.run(). To do this, you have to import asyncio and also you have to add a method to your App class. See the example below:
import asyncio
######## MAIN APP ########
class ExampleApp(App):
def build(self):
#Your app stuff here
async def kivyCoro(self): #This is the method that's gonna launch your kivy app
await self.async_run(async_lib='asyncio')
print('Kivy async app finished...')
# This func will start all the "tasks", in this case the only task is the kivy app
async def base(self):
(done, pending) = await asyncio.wait({self.kivyCoro()},
return_when='FIRST_COMPLETED')
if __name__ == '__main__':
instanceApp = ExampleApp() #You have to instanciate your App class
asyncio.run(instanciaApp.base()) # Run in async mode
With the code above you'll be able to run tour kivy app as a task (concurrently).
So far, we just have run the kivy app in async mode (concurrently). To add other task inside the Kivy running loop:
import asyncio
######## MAIN APP ########
class ExampleApp(App):
def build(self):
#Your app stuff here
async def kivyCoro(self): #This is the method that's gonna launch your kivy app
await self.async_run(async_lib='asyncio')
print('Kivy async app finished...')
async def task2InsideKivyLoop(self): #Here you declare the other task
print('Another task running inside the kivy loop')
await asyncio.sleep(1)
# This func will start all the "tasks", in this case the only task is the kivy app
async def base(self):
(done, pending) = await asyncio.wait({self.kivyCoro(), task2InsideKivyLoop()},
return_when='FIRST_COMPLETED')
if __name__ == '__main__':
instanceApp = ExampleApp() #You have to instanciate your App class
asyncio.run(instanciaApp.base()) # Run in async mode
As you can see, to add another task inside the KivyLoop we just have to declare it as a async method of the App class, then just add it to asyncio.wait()
If you want to run the other task outside the kivyLoop you have to do the fllowing:
import asyncio
######## MAIN APP ########
class ExampleApp(App):
def build(self):
#Your app stuff here
async def kivyCoro(self): #This is the method that's gonna launch your kivy app
await self.async_run(async_lib='asyncio')
print('Kivy async app finished...')
# This func will start all the "tasks", in this case the only task is the kivy app
async def base(self):
(done, pending) = await asyncio.wait({self.kivyCoro()},
return_when='FIRST_COMPLETED')
######### GLOBAL COROUTINE #######
# Here you can import functions from other python files or just declare a global func
async def GlobalTask():
for i in range(10):
print('Other concurrently global task... ',i)
await asyncio.sleep(1)
if __name__ == '__main__':
async def mainThread():
instanceApp = ExampleApp() #Instanciate your App class
a = asyncio.create_task(instanceApp.base()) #Run kivyApp as a task
b = asyncio.create_task(GlobalTask()) #Run Global func as a task
(done, pending) = await asyncio.wait({a}, return_when='FIRST_COMPLETED')
asyncio.run(mainThread())
The examples above would let you do any async task during the kv loop wheter inside the kvLoop or not

The code:
if __name__ == '__main__':
ChatApp().run()
p1 = Process(target=receive)
p1.start()
will run your ChatApp, and then after you close the ChatApp, it will run the receive process. They will not run at the same time because the ChatApp().run() will not return until the ChatApp closes. Try changing the order to:
if __name__ == '__main__':
p1 = Process(target=receive)
p1.start()
ChatApp().run()

on_text_validate of the TextInput with id:height in the string cuboid, I want to get the text from the text input with something like: self.screen.main.height.text, however, to do that I would have to add main:main and height:height to Screen. How would I do this?

I suggest refactoring your code. Rather than re-inventing the capabilities of ScreenManager, just use ScreenManager. In your kv string, replace the FloatLayout with:
ScreenManager:
CubeScreen:
CuboidScreen:
ConeScreen:
and use your additional kv strings (like cube) as the basis for additional rules in your kv string. Something like:
<CubeScreen>:
Label:
text: "The Volume and surface area of a Cube:"
pos_hint: {"x":0.1, "y":0.8}
text_size: self.size
FloatLayout:
Label:
text:"Side:"
pos_hint: {"x":0.1, "y":0.7}
text_size: self.size
.
.
.
And define each Screen class in your py, like:
class CubeScreen(Screen):
def get_cube_area(self):
.
.
.
And in each of the new classes (like CubeScreen) you can define methods for calculating area, volume, etc, and you can access the TextInputs easily using their ids. And your on_text_validate in each Screen can just call the appropriate method from that Screen (like on_text_validate: root.get_cube_area()).

Python Kivymd - AttributeError object has no attribute

Not sure where I'm going wrong, When changing the value of MDSlider it should update a label but I receive the error
the kv is loaded as a string within my py file, if I test out the slider by simply printing the value to the console it works. but when I try to update a label get the following error??

kivyMD: write data into file and evaluate test

I am a beginner and I am trying to make a personality test in kivymd. There are 24 questions where you can choose one of the 4 options (d, i, s, n).
Evaluating the test, I want to write out how many certain letters an user choose. I want to save it to a file. I already write a test name from textfield, but I want it as tuple or list.
I think something like this:
Test1[d=2,i=5,s=8,n=9]
Do you have any idea how can I do that? I tried it with functions d(),.. but it doesn't work
