This adds the specified Gtk widget
to the hierarchy defining a graphical
interface by giving it a parent
and a place in the parent's container.
This is then followed by a call to
gtkShow
to make the
widget visible.
gtkAdd(parent, ...)
TRUE
,
indicating success.
This will be changed to be a widget.
Perhaps we will add an option to allow a scrolled
container or a pane to be added in which case the
result will be that newly created container widget.
