[Kwin] Re: Embedding multible java applets and focus problems

[Leon Bottou]

Incidentally I have another patch for qxembed.
But I do not want to apply it while you are making
the XAddToSaveSet changes.

See <http://bugs.kde.org/show_bug.cgi?id=66938>.
The proposed patch is attached to the bug report.

It reimplements the focus navigation with tab/backtab
using a code that pays more respect to Qt.  The new
code makes extensive use of QWidget::focusNextPrevChild()
to search suitable focus windows.  Once this is done,
it detects whether we have been looping around and sends
the XEMBED messages as mandated by the spec.

Please review.
