Kivy with Python tutorial Part 9 - Builder for loading .kv Files Smarter

In this Kivy application development tutorial, we cover the Kivy builder, which can be used to explicitly load in your Kivy files, rather than using the naming conventions for the main application class.

Like any Computer Scientist, I've had to watch quite a few coding tutorials. You're videos, by far, have been some of the most well thought, professional, and helpful I've seen. Awesome job.

Dude, you are doing awesome work. Seriously the way you're explaining is like a smooth learning experience. Keep doing the same.

I just want to say great tutorials. I love learning python and the way you teach material is very concise and easy to understand!

Nice! About naming kv files being messy, I just use self.load_kv("kv_file.kv") in the build. It's way easier

[dmitryponyatov]

about Builder.load_string you can say "your applicaton can work like webbrowser load forms from remote server or database text field via Builder.load_string()"

Hey Sentdex! Thank you for all your tutorials. I would like to know if you could please give me a suggestion/ instruction on how to make a splash screen for a desktop application using kivy? I truly hope you see this comment.

Hey, you said that the way to change the screen in tkinter is loading all of them in the background, but there is ttk.Notebook

Im trying to write dynamic buttons to a separate python file and import them to the main GUI without using kv file, is it possible? This single problem has taken me some time.

Hi! thank you so much for your video? My task is build a desktop app with a 3d enviroment in it in python, is it kivy a good solution to do it? I found kivy3 but i need to import and show an STL file and i coud find anything about it.

hi Dex when I try either one of the two building ways you showed us and run the program i don't see that i've created in my .kv file but i only see a black window.please do u know what the problem is?

[FabioRuning]

Hi  thank you  for video.
I copied same way and it didn't work.
I realized that .load_file didn't appear automatically

 return presentation()
 TypeError: 'NoneType' object is not callable

Do you have one tip?

[milanshah]
