Yes, you're right it is in Qt4, and it does sound possible to do what
Fredrik wants with the QX11Embed classes.

Those classes aren't included in the generation of the Smoke library
that the current release of Qt4 QtRuby uses. I've now added the header
QtGui/qx11embed_x11.h to the smoke/qt/header_list file so the
QX11EmbedContainer and  QX11EmbedWidget classes, and so they will be in
the next release.
