Problems Sending Input/Focus to Plug Window - Solution

[Benjamin Schnitzler <benjaminschnitzler googlemail com>]

Ok, it's already implemented, though using a huge framework like gtk can
sometimes make it a tough job to find the right trigger. The plug/socket example
could be a bit more detailed, but I guess the gtk Developers are quite busy,
like us ;). Anyways, here is the solution:

socket->child_focus(Gtk::DIR_TAB_FORWARD);

For your convenience, the link to Gtk::DirectionType:

One little question remains: Is there any way to put the focus to an embedded
xterm? It somehow seems, that xterm does not follow the xembed protocoll
correctly.

Be wild and genius,
