The appRunner.main object
This article describes a deprecated feature as of Panda3D 1.10.0.
For instance, if you write Python code that does this:
base.appRunner.main.base = base
plugin = document.getElementById('myPlugin') plugin.main.base.toggleWireframe()
which calls base.toggleWireframe(), a method that toggles wireframe rendering in the Panda3D window.
