Panda3D add-on for Kivy integration.

Panda3D-Kivy

A Panda3D add-on for Kivy integration.

The aim is to make the integration of Kivy apps into a Panda3D application almost transparent. Potential uses include creating on-screen GUI, or even RTT 3D UI's.

Usage:

First, import panda3d_kivy.app.App - make sure you do this before importing any Kivy-related stuff:

from panda3d_kivy.app import App

Then, as usual in Kivy, create a subclass of this App, and use build() or the KV autoloading system to populate your widget tree:

from kivy.uix.button import Button

class Example(App):
    def build(self):
        return Button(text='Hello, world!')

You can then instanciate and run this app inside the __init__ of your Panda ShowBase, after running ShowBase.__init__(self). You will need to create a display region for your kivy app, sized according to your needs. You must then pass it as well as your showbase as arguments to the kivy app instanciation, and finally call app.run() as you normally would:

from direct.showbase.ShowBase import ShowBase

class PandaApp(ShowBase):
    def __init__(self):
        ShowBase.__init__(self)

        # Full screen display region, adjust as needed
        display_region = self.win.make_display_region(0, 1, 0, 1)

        self.kivy_app = kivy_app = Example(
            display_region,
            panda_app=self,
        )
        kivy_app.run()

        # The rest of your ShowBase code here

Voilà! You should have a working Kivy UI in your Panda application. Have fun!
