win32: child window not found in child's parent's children

I have an Internet explorer page which generated a pop-up. I can get the parent from the pop-up window's handle:

>>> child.handle
15208472
>>> win32gui.GetParent(child.handle)
33230502

But I can't find the child's handle by using EnumChildWindows:

>>> win32gui.EnumChildWindows(win32gui.GetParent(child.handle), lambda hwnd,p: child_handles.append(hwnd), None)
>>> len(child_handles)
39
>>> child.handle in child_handles
False

I've done this recursively as well (getting the children of all the children) and still no child handle to be found. Why might this be the case?

Solution

  • A popup window isn't a child window, so can't be enumerated with EnumChildWindows.

    When you called win32gui.GetParent you actually got the "owner" window of the popup, but "owner" and "parent" are two different things. See the MSDN entry for more infromation.
