Re: How to know that a window is still open

[Martin Senger <M.Senger@dkfz-heidelberg.de>]

Thank you very much for valuable replies to my question, or questions.
After receiving answers from Gordon, John Ray and Richard Bullington,
I finally learned how to recognize that a given window is a top-level
window, or not.

Summary:
   The simple test if (window.name=="") really works (also on UNIX, Gordon).
   My mis-understanding was that I replaced 'name' in the line above,
   with a real window name (e.g. helpwin, setupwin etc.), but it must be
   exactly 'name' (name is a property, isn't it?).

But I did not succeed with the second problem (which seemed simpler):
How to know that a window which was opened by me is still open? I know
that an obvious solution is to remember value returned from open() and
then use it in close() method. But I do not want to remember it because:
1. There are problems how to protect stored value over reload and resize.
2. I am opening some windows from href (with target), so I do not have
   any returned value.
I think that should be a method how to ask about a window whose name is
known. Unfortunately, I do not know how to ask...

Thanks againt for your help.
Best regards,
Martin Senger
