Where is the code for the window and the icon?

Hi, I am new to The Panda3D Source Code,
I want to change the icon, the name, and the name of the window.
Any Assistance please.
P.S: I know C++ But too much, Also I am 9 years old.

Ok so changing the name and icon are all things that are done when deploying the project you are working on. You can read more about that here https://docs.panda3d.org/1.10/python/distribution/index. Changing the name of the window is done in code. Here is an example with python

from panda3d.core import loadPrcFileData
loadPrcFileData("", "window-title Window")

If you have any other questions, feel free to ask!
