[Tkinter-discuss] winfo_id on OS/X

[Jeff Hultquist]

I am trying to use tkinter with the Panda3D  (panda3d.org <http://panda3d.org/>)  graphics library.  I want to position a graphics window into a tkinter frame.  

Attached below is some sample code that uses the frame.winfo_id() as the argument to Panda3D’s setParentWindow method.

This works on Linux and Windows, but seg-faults on OS/X.   It appears the winfo_id is not valid on OS/X.

How can we get a proper handle for the parenting of the 3d view into a tkinter frame?

FWIW, there is a thread is ongoing on the Panda3D forum, but the answer seems to lie deep inside tkinter.

Many thanks.

from direct.showbase.ShowBase import ShowBase
from panda3d.core import WindowProperties
import Tkinter

base = ShowBase(windowType='none')
base.startTk()

frame = base.tkRoot
frame.update()

id = frame.winfo_id()
width = frame.winfo_width()
height = frame.winfo_height()

props = WindowProperties()
props.setParentWindow(id)
props.setOrigin(0, 0)
props.setSize(width, height)

base.makeDefaultPipe()
base.openDefaultWindow(props=props)   # —— on OS/X, we segfault here

scene = base.loader.loadModel("environment")
scene.reparentTo(base.render)

base.run()
