Kivy Core Concept - Using an `id` to Reference a Widget 

That trick of use a print statement to know which ids are related to, is simply amazing

literally spent 2hours trying to figure it out, thanks for the video

Until I come across to this video it used to take me a lot of time to reach the widgets in my custom widgets and I have had to write very long lines to reach them, now everything is crystal clear to me, thanks a lot for this helpful video

This tutorial is the best among the rest. The others is not clear, but yours is

I’m new to programming and Kivy and this basic idea I just couldn’t find/comprehend but you really helped man! Thank you!

Erik, thank you for very interesting and useful videos of kivymd. My name is Audrey, I live in Moscow, Russia.

Best kivy and kivymd tutorial...

You're actually a god i've been stuck on this for so long

I really appreciate the way you explain things.

Thanks for the debug-advise! You are amazing man!

Erik your work is very helpfull . thanx for sharing your information with Us ♥

I can't believe this isn't listed anywhere on the docs. Thanks!

I am on 1:20 and i already know this gonna be awesome tutorial!)

Excellent tutorial, many ways to Rome in kivy.

Awesome tutorial. Need help on a previous tutorial(MDToolbar). How can i use the vertical dots to open a dropdownmenu with 4 items(label 1, label2, label3, label4)?

Nice work, keep it up!

Thank you very much for this helpful video.

please help!: i have created a special class and i have not used it in the builder string but used it in a dialog box like this content = Secialclass() in that special class i have a text field how do i reference text in that? if i add the special class in main builder srting the text field comes on the mai page and in dialog box too

Very explicit tutorial Erik. Its very difficult to get clear explanations on ids. One question I have is, when do ids get created? This is the situation: i have a set of labels that need to be populated prior to showing the screen. How would you tackle it? Thanks.

Ok so this works good on the same screen, how would you reference 1 screens text input and update a label on screen 2?

thank u very much, this video helped me a lot. if it was possible on youtube to like one video 1000 times, i will put on this video

Bro you are just like my elder brother which doesn't exit but, you are guiding me through your videos Please also upload a video a video about packaging kivy app for windows 🙏

Superb video! I would like to see you generate a CRUD Kivy / Python video that focuses on adding, deleting, updating, etc. records in a database.

Is there a way to set id in the main file, instead of the kv file?

Can you use the id for layouts

I'm getting "super' object has no attribute '__getattr__'" error, im using kivymd

Erik thanks for this tutorial! Could you make a tutorial how to make number picker (scrollin wheel number picker) by using kivy? If it's possible... Thanks in advance!

When i add TextInput: to my kv file it breaks my window any ideas how to fix this?

Hello can you help me with the code in kivymd!! I want to store data in the form of dictionary which when user inputs certain keyword , the value stored in the dictionary related to the keyword print in the app!!

@6:55 What if I want to add SpecialGridLayout dynamically from python code from another class.

how do i access these ids from another class, inside of the main.py script?

AttributeError: 'PongGame' object has no attribute 'root' I am getting this error when I am trying to refer label like this player1_score = self.root.ids.score1

can you do something like search video.

I have been working on this project where I need to to change the text of a label according to a the text written in a textinput in a different screen..... Is there a way to do that.

I'm having big problems with referencing ids. I wonder if you might help. I've had to initialise the method and the parent class FloatLayout. This is for an ebook reader so I've got an object instance of the book contents which I'm passing about between methods and classes as I parse the info. My problem is that it will only accept "self" in the __init__ method - not from any of my other methods- which is a nightmare. When there's an event in KV, easy-peasy - I can just send it straight to python or to another widget. When there's an event in python (eg, I want to get self.height for an id within a loop) then I'm finding I can't just reference a module in the root class that returns self.root.ids.id_name.height... If I pass "self" it thinks I'm referring to by book loading instance (nothing to do with kivy) and I know of no way to explicitly name the object to fetch the id. It's kinda set up like this (boiled down version): : FloatLayout: id: some_id Label: id: some_other_id --- --- --- class RootClass(FloatLayout): def __init__(self, **kwargs): super(MyLayout, self).__init__(**kwargs) someVariable = self.root.ids.some_other_id.height

Hi Erik - perhaps you could shed some light on this: My root widget is a FloatLayout, divided into two GridLayouts of 0.1 and 0.9 respectively (I want a "top menu" which is persistent throughout the app, as in friendly fitness). Is there anyway I can make the loginscreen override this logic (I don't want the "top menu" to be visible before you log in). Or is there a more elegant way to solve this?

how can I assign a variable to the reference of my widget in my class instead of in a function?

In .Py file why do you write ids instead of id as mentioned in .kv file?

When should one use ':' and when '=' in kv file?

the main windows is loading but not the widgets

I can't set id in kivy v2.0 any more with python like that Button(id="myid") I hate kv scripts

can u drop your facebook account pls ? Ide discuss some point and ideas with u if u have time for that
