How to put "ID" on MDDialog without use .kv structure

[berk berk]

Hey guys, I have a problem with MDDialog. Here is sample code:

....
if not self.dialog:
            self.dialog = MDDialog(
                title="Address:",
                type="custom",
                content_cls=MDBoxLayout(
                    MDTextField(
                        hint_text="City",
                    ),
                    orientation="vertical",
                    spacing="12dp",
                    size_hint_y=None,
                    height="120dp",
                ),
                buttons=[
                    MDFlatButton(
                        text="OK",
                        theme_text_color="Custom",
                        text_color=self.theme_cls.primary_color,
                    ),
                ],
            )
        self.dialog.open()
....
I want to put id on MDDialogs that its has TextField. But I couldn't. I now if I use .kv structure to create a content class like <Content> then i put on content_cls=Content() that's it. 
But how to put "id"  on normal Python structure like top sample?

Normally;
i=TextField(text="text")
self.ids['here']=i 
but I confused in this sample(MDDialog).

Thanks,

The short answer is you don’t.

The id is a kv capability.  When the kv file is processed, the ids dict is populated.

You can address specific widgets or walk the widget tree.  I added some exampled below:

 

from kivymd.app import MDApp
from kivymd.uix.boxlayout import MDBoxLayout
from kivymd.uix.button import MDFlatButton
from kivymd.uix.dialog import MDDialog
from kivymd.uix.floatlayout import MDFloatLayout
from kivymd.uix.textfield import MDTextField


class Example(MDApp):
    dialog = None

    def build(self):
        self.theme_cls.theme_style = "Dark"
        self.theme_cls.primary_palette = "Orange"
        return (
            MDFloatLayout(
                MDFlatButton(
                    text="ALERT DIALOG",
                    pos_hint={'center_x': 0.5, 'center_y': 0.5},
                    on_release=self.show_confirmation_dialog,
                )
            )
        )

    def show_confirmation_dialog(self, *args):
        if not self.dialog:
            self.dialog = MDDialog(
                title="Address:",
                type="custom",
                content_cls=MDBoxLayout(
                    MDTextField(
                        hint_text="City",
                    ),
                    MDTextField(
                        hint_text="Street",
                    ),
                    orientation="vertical",
                    spacing="12dp",
                    size_hint_y=None,
                    height="120dp",
                ),
                buttons=[
                    MDFlatButton(
                        text="CANCEL",
                        theme_text_color="Custom",
                        text_color=self.theme_cls.primary_color,
                    ),
                    MDFlatButton(
                        text="OK",
                        theme_text_color="Custom",
                        text_color=self.theme_cls.primary_color,
                    ),
                ],
            )
        self.dialog.open()
        print(f'{self.dialog.content_cls=}')
        print(f'{self.dialog.content_cls.children}')
        self.dialog.content_cls.children[0].text = '200 Main Street'
        self.dialog.content_cls.children[1].text = 'Anytown'
        print('-' * 80)
        for w in self.dialog.walk(restrict=True):  # widgets under dialog
            print(w)
        print('-' * 80)
        for w in self.dialog.walk(restrict=True):
            if isinstance(w, MDTextField):
                print(f'TextFiled: {w}', end=' ')
                if w.hint_text == 'City':
                    print('The City TextInput')
                if w.hint_text == 'Street':
                    print('The Street TextInput')



Example().run()
