Could someone in the know please explain the intention of
PostCreate(). What happens when I call it, that kind of thing.
Or is it meant to be a hook which is called automatically by
Create() or some other mechanism?
What are some potential use-cases?
Thanks

When you use the "Pre" method to create a window instance so you can later call the Create method, there are a few hosekeeping things that are needed to fully link up the real class with the pre-created instance. PostCreate does that for you. For example:
class TestDialog(wx.Dialog):
def __init__(
self, parent, ID=-1, title="",
size=wx.DefaultSize, pos=wx.DefaultPosition,
style=wx.DEFAULT_DIALOG_STYLE
):
pre = wx.PreDialog()
pre.SetExtraStyle(wx.DIALOG_EX_CONTEXTHELP)
pre.Create(parent, ID, title, pos, size, style)
self.PostCreate(pre)
It simply transfers the this and thisown attributes, and calls _setOORInfo and _setCallbackInfo if needed.

Oops, that last line should have been indented.

Oh, okay, so I don't need to do that manually anymore. Thanks!
