crash when setting a parent window from a wx handle on osx

[Hypnos]

When grabbing a handle from a wxPython window using GetHandle() and passing that in Panda's WindowProperties.setParentWindow method, a crash occurs.

Crash information is available at this forum thread:

I don't see a crash, but I get 2 separate windows (the attempt to set the handle does nothing). Tested on OSX 10.5 and 10.6 with panda 1.7.2. It works properly under windows7.

Here is some simple code that shows the issue:
import direct.directbase.DirectStart
from direct.task import Task
import wx
from panda3d.core import WindowProperties

app = wx.PySimpleApp()
def handleWxEvents(task=None):
    while app.Pending(): app.Dispatch()
    return Task.cont

taskMgr.add(handleWxEvents, 'handleWxEvents')

frame = wx.Frame(None, -1, 'My wx frame')
base.windowType = 'onscreen'
props = WindowProperties.getDefault()
props.setParentWindow(frame.GetHandle())
base.openDefaultWindow(props = props)
frame.Show(True)

run()

I don't think that it's even possible to support window reparenting under OSX through the Carbon interface. We'd probably need to rewrite the whole thing to Cocoa, which is not easy (and brings tons of other difficulties with it).

In the meantime, we have Cocoa support in Panda3D, which resolves this issue. It does require a Cocoa version of wx to work, though. It is theoretically possible to reparent Cocoa views to a Carbon window by creating a HICocoaView embedding Panda's NSView, but I'm not sure that it's worth the effort given that Carbon is being phased out everywhere.

Setting to Won't Fix since Carbon support will be dropped soon.
