I can't call ids when I declare it on main.py

[Victor Leal]

I am having problems when working with a TextInput in a function and need to call its value in another function.

I need to use the tInput.text and cInput.text values on add_Widget_popup function but i can't

Error: 

File "main.py", line 246, in add_Widget_popup

     tAux = self.ids.tAux.text

   File "kivy\properties.pyx", line 841, in kivy.properties.ObservableDict.__getattr__

 AttributeError: 'super' object has no attribute '__getattr__'

main.py

class Tarefas(Screen):

tarefas = []

cmds = []

def add_Widget_popup(self, *args):

tAux = self.ids.tAux.text

cAux = self.ids.cAux.text

if(tAux != ''):

pass

else:

tAux = '[color=ff3333]Sem descrição[/color]'

if(cAux != ''):

pass

else:

cAux = '[color=ff3333]##[/color]'

self.ids.box.add_widget(Tarefa(text = tAux, pText=cAux))

self.tarefas.append(tAux)

self.cmds.append(cAux)

self.saveData()

def addWidget(self, *args):

box2 = BoxLayout(orientation='vertical', padding=10, spacing=10)

Inputs = BoxLayout(padding=5, spacing = 10, orientation = 'vertical')

pop2 = Popup(title='Adicionar Comando', content=box2, size_hint=(None, None), size=(100, 30))

tlInput = Label(text = 'Descrição:', size_hint_y = None, height = 20)

tInput = TextInput(id='tAux', multiline = False, size_hint_y = None, height = 30)

clInput = Label(text = 'Comando:', size_hint_y = None, height = 20)

cInput = TextInput(id='cAux', multiline = False, size_hint_y = None, height = 30)

confirm = Botao(text = 'Confirmar', on_press=self.add_Widget_popup, on_release=pop2.dismiss)

Inputs.add_widget(tlInput)

Inputs.add_widget(tInput)

Inputs.add_widget(clInput)

Inputs.add_widget(cInput)

Inputs.add_widget(confirm)

box2.add_widget(Inputs)

anim = Animation(size=(500, 250), duration=0.05, t='out_back')

anim.start(pop2)

pop2.open()

ids are kv only, they don't do anything in Python, in fact the property is pointless and should probably be removed.

You can add things to the ids dict manually if you want, or pass references around some other way.

I tried, but i'm a beginner in python and kivy,  I could not reference otherwise.

I usually use python to edit attributes of widgets from it's ID, it is possible. 

If what you're trying to do is to change the text of a widget, in your kv define it like that:

Label:

    id: whatever

    text: ""                         #you can put any default text here

And then from python, when you want it to change do:

self.ids.whatever.text = "new text"

I think the error in your code is trying to use the add_Widget like that.

Use self.ids.<id>.<attribute> just in attributes that already exist

I wonder if it's just an issue of calling it before it's created?

TAux text doesn't exist yet, right ?
