问题 I'm attempting to create a custom TreeViewNode to use with a TreeView. Just want an image with a label next to it, nothing more. Yet attempting to create a custom node... even replicating how it's done in the source doesn't yield the same results.

问题 I am using kivy's file chooser and when there is a file of a folder with an Hebrew name, it prints gibberish... I want to support different languages if possible. Tried to change the font name in the file chooser, didn't work for me. Can you help me find out what am I doing wrong? 回答1: It's not only FileChooser - all instances of Label in Kivy use Roboto font as a default, which doesn't seem to support Unicode characters. Try running this code: from kivy.app import App from kivy.uix.label

问题 Good evening, I'm trying to combine kivy's actionbar with a screenmanager. I've gotten to the point where I can switch through screens, but am not able to get my actionbar to show. I've followed alot of examples, but none that can help me with my problem. I'm fairly new to kivy so I haven't been working with it for very long.
