QXEmbed grabbing mouse

[Owen Taylor]

I don't really have enough context here, but certainly focus shold be
fully handled in both the the original XEMBED protocol and the revised
version that I posted last spring.

When the client app needs to get the focus, what it does is send a
XEMBED_REQUEST_FOCUS event to the embedder, and the embedder responds
by giving focus to the client.

See:

 http://www.freedesktop.org/standards/xembed/html/messages.html

As I recall, this worked properly in my test app for QXEmbed within
QXEmbed as well as in mixed QXEmbed/GTK+ embedding.

Regards,
                                        Owen
