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

[@drarn96]

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

[@erik-sandberg]

Oh yeah, absolute game changer :)

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)?

[@erik-sandberg]

For the dropdown menu you'll need to use the MDDropdownMenu widget. I'll have a video coming on that one soon :)

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

[@upcomingvillain]

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

[@r.castro340]

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.

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

[@sci3nttechable611]

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?

[@erik-sandberg]

Try having your root widget be a ScreenManager. Then the first screen of the screenmanager should be your login screen. Once the user logs on, switch screens to your 2nd screen, which is your current FloatLayout. Your 2nd screen code would be all the exact code you have right now, except indented once with a Screen widget before the Floatlayout.
